Labconco XPert 3950402 4' Filtered Balance System with Guardian 1000 Digital Airflow Monitor – Used and Refurbished

The Labconco XPert 3950402 Filtered Balance System is a 4-foot powder containment enclosure designed to protect laboratory personnel during weighing, transfer, and manipulation of powders and particulates. Combining a spacious balance-compatible work area with an integral blower, 99.99% efficient exhaust HEPA filter, and Guardian 1000 Digital Airflow Monitor, the XPert provides a self-contained solution for pharmaceutical powder weighing, analytical sample preparation, dry chemical handling, and other particulate-generating laboratory procedures.

Unlike an XPert Balance Enclosure that requires connection to a separate exhaust system, the Labconco 3950402 incorporates its blower and HEPA filtration system directly into the upper plenum. Contaminated air is drawn away from the operator, passed through the HEPA filter, and returned to the laboratory as filtered exhaust for appropriate particulate applications. This eliminates the need for external ductwork or a separate filtered exhauster during normal recirculating operation.

The 3950402 also incorporates Labconco's Guardian 1000 Digital Airflow Monitor. The monitor continuously measures airflow and displays actual face velocity while providing audible and visual warnings if airflow moves outside the established operating range. This gives laboratory personnel immediate feedback on one of the most important operating parameters of a powder containment enclosure.

With an overall width of 48 inches and an interior approximately 45.6 inches wide × 23.4 inches deep × 22.7 inches high, the XPert 3950402 provides enough room for many analytical balances, microbalances, precision balances, and supporting sample-preparation equipment. Labconco's aerodynamic Clean-Sweep airfoil, upper containment sash foil, upper dilution air supply, side-entry airfoils, and zone-perforated rear baffle help provide effective containment while limiting airflow disturbances around sensitive weighing instruments.

This Labconco XPert 3950402 is used and refurbished by American Instrument Exchange. AIE technicians inspect and test the system before shipment, including blower operation, airflow, Guardian 1000 monitor, lighting, controls, sash operation, and other installed functions. The enclosure is thoroughly cleaned and includes a 90-day warranty.

Overview

The Labconco XPert Filtered Balance System was developed around a problem commonly encountered in pharmaceutical, biotechnology, chemical, and analytical laboratories: safely containing powders while maintaining an environment suitable for accurate weighing.

Powders can become airborne when containers are opened, material is scooped or transferred, samples are weighed, or residue is cleaned from laboratory surfaces. When the material is potent, toxic, irritating, or otherwise hazardous, even relatively small weighing procedures can create an occupational exposure concern.

A conventional chemical fume hood can provide containment, but its higher airflow and larger sash opening may create conditions that interfere with sensitive balance measurements.

The XPert takes a different approach.

The enclosure combines controlled inward airflow with a relatively small sash opening and aerodynamic airflow-management features specifically designed around laboratory weighing.

The 3950402 adds a built-in blower, exhaust HEPA filtration, and digital airflow monitoring, creating a complete powder-containment workstation without requiring a separate filtered exhauster.

Common Applications

The Labconco XPert 3950402 is well suited to pharmaceutical powder weighing, active pharmaceutical ingredient handling, dry chemical transfer, toxic-powder containment, analytical sample preparation, formulation research, quality-control testing, environmental sample weighing, gravimetric procedures, fine-chemical handling, research-compound preparation, mold and asbestos sample weighing, and other laboratory procedures involving appropriately filterable particulates.

Its 4-foot width also provides sufficient working space for procedures that require a balance plus sample containers, weighing vessels, transfer tools, or other small laboratory equipment.

The XPert is primarily a particulate containment system. Applications generating hazardous gases or significant chemical vapors require additional application assessment and an appropriate containment or exhaust strategy.

Ideal Laboratory Types

The XPert 3950402 is particularly well suited to pharmaceutical research and development laboratories, biotechnology companies, analytical laboratories, chemical laboratories, environmental testing facilities, industrial quality-control laboratories, formulation laboratories, contract research organizations, forensic laboratories, academic research facilities, and other laboratories routinely working with powdered materials.

Its combination of containment, digital airflow monitoring, and a large 4-foot work area also makes it attractive for laboratories establishing dedicated powder-weighing stations.

Guardian 1000 Digital Airflow Monitor

The Guardian 1000 Digital Airflow Monitor is one of the most important features distinguishing catalog number 3950402 from other XPert configurations.

Rather than providing only a simple status indicator, the Guardian 1000 continuously monitors airflow and provides a digital readout of actual face velocity.

If airflow moves outside the established set-point range, the system alerts the operator with audible and visual alarms.

This gives laboratory personnel immediate information about containment conditions before and during a weighing procedure.

For facilities with documentation or monitoring requirements, the Guardian 1000 also provides an RS-232 communications capability for connection to a user-supplied computer.

Powder and Particulate Containment

The primary purpose of the XPert 3950402 is personnel protection during procedures that can release airborne powders or particulates.

The built-in blower draws room air inward through the sash opening.

This inward airflow helps create a barrier between material inside the enclosure and the operator's breathing zone.

Particles released during weighing or transfer are carried toward the rear baffle and through the exhaust HEPA filtration system.

For appropriate particulate applications, the HEPA-filtered air can then be returned directly to the laboratory.

Built-In 99.99% HEPA Filtration

The XPert 3950402 incorporates an exhaust HEPA filter rated 99.99% efficient for particles 0.3 micron in size.

HEPA filtration makes the system particularly useful for dry powders and other particulate contaminants.

Because the filtration system is incorporated into the enclosure, laboratories do not need to purchase and install a separate HEPA exhauster for normal operation.

HEPA filtration captures particles rather than chemical gases and vapors. Procedures involving volatile chemicals require a containment system appropriate for those contaminants.

Built-In Blower

A motorized impeller is incorporated into the XPert's upper plenum.

This allows the enclosure to generate its own containment airflow without connection to a separate remote blower.

Integrating the blower directly into the system simplifies installation and makes the XPert a relatively self-contained laboratory workstation.

The blower is dynamically balanced and mounted on vibration-isolation supports to minimize disturbance to sensitive balances positioned within the enclosure.

Vibration Isolation for Sensitive Weighing

Balance performance can be affected by vibration as well as airflow.

This is especially important for analytical and microbalances capable of resolving very small changes in mass.

Labconco mounts the XPert's motorized impeller on isolation supports to reduce transmission of blower vibration into the work area.

This design helps make the system better suited to sensitive weighing procedures than a generic enclosure with a conventional blower mounted directly to its structure.

Deep 23.4-Inch Interior

The XPert 3950402 provides an interior depth of approximately 23.4 inches.

This gives laboratories enough space to accommodate many large analytical, precision, and microbalances while maintaining room for weighing vessels, sample containers, spatulas, weigh boats, and related accessories.

The 4-foot model also provides approximately 45.6 inches of interior width, making it substantially more spacious than the 2-foot XPert configurations.

Four-Foot Working Width

The 4-foot configuration is particularly useful when the laboratory needs more than a compact single-balance station.

Its larger work area can accommodate a substantial analytical balance along with sample containers and preparation accessories.

The additional width can also improve workflow when repeated weighing procedures require several containers, reference materials, or supporting tools to remain inside the enclosure.

Equipment should still be arranged so the front airfoil and rear baffle remain unobstructed.

9.4-Inch Sash Opening

The XPert 3950402 uses an approximately 9.4-inch-high working sash opening.

Keeping the opening relatively small reduces the amount of air that must be moved to establish the required inward airflow.

Lower airflow demand is particularly beneficial for weighing applications because excessive air movement can interfere with balance stability.

The hinged sash can also be raised when additional access is required for equipment loading.

Clean-Sweep Airfoil

Labconco's Clean-Sweep airfoil helps guide room air smoothly into the enclosure and across the work surface.

Smooth airflow at the front opening reduces turbulence while helping maintain containment.

This is particularly important around a sensitive balance, where unnecessary air disturbances can increase settling time or produce unstable measurements.

The front airfoil should remain free of containers, paperwork, equipment, and other obstructions during use.

Upper Containment Sash Foil

The upper containment sash foil helps direct airflow into the enclosure near the upper portion of the front opening.

This helps move contaminants away from the operator's breathing zone and toward the enclosure's filtration system.

Together with the front airfoil and rear baffle, the sash foil forms part of the XPert's integrated aerodynamic containment design.

Upper Dilution Air Supply

The upper dilution air supply introduces room air near the top of the sash.

This helps dilute contaminants in the upper region of the enclosure while bathing the rear surface of the sash with clean air.

The result is improved airflow management across an area that can otherwise become susceptible to stagnant zones.

Zone-Perforated Rear Baffle

A perforated rear baffle helps distribute airflow across the work area.

Instead of concentrating exhaust airflow at one small point, the baffle encourages relatively uniform movement toward the rear of the enclosure.

This promotes particulate capture while helping reduce areas of excessive air velocity around the balance.

The baffle pivots for easier cleaning.

Side-Entry Airfoils

Side-entry airfoils allow room air to sweep across the interior glass surfaces.

This helps improve containment around the sides of the enclosure and reduces stagnant regions adjacent to the glass.

The side-entry design works with the other aerodynamic features to maintain containment without relying solely on high exhaust velocity.

Tempered Safety Glass

The XPert uses 1/4-inch-thick tempered safety glass for the front sash and side panels.

Tempered glass provides good scratch, fire, and chemical resistance while maintaining excellent visibility into the work area.

Glass also dissipates static charge more effectively than many plastic enclosure materials.

Static control can be especially relevant when manipulating fine powders that may otherwise adhere to surfaces or interfere with weighing procedures.

Ergonomic Angled Sash

The XPert incorporates an approximately 10-degree angled front sash.

This improves the operator's view of the balance and sample while allowing a more comfortable working posture.

The sash is hinged and can pivot upward and lock for loading equipment into the enclosure.

A wiping seal helps maintain containment around the sash.

Intrinsically Safe Negative-Pressure Design

The XPert's blower and filtration arrangement is designed so that the positive-pressure impeller is surrounded by a negative-pressure plenum.

If leakage were to occur around the positive-pressure portion of the system, unfiltered air would be captured by the surrounding negative-pressure area and directed back through filtration.

This design provides an additional level of containment within the enclosure's exhaust system.

Bag-In/Bag-Out HEPA Filter Disposal

The XPert incorporates a true bag-in/bag-out system for HEPA filter removal.

This feature is particularly valuable when the filter has accumulated potent or hazardous powders.

The filter can be contained during removal rather than openly handled after it has collected contaminants.

Filter replacement involving hazardous materials should be performed using appropriate procedures and by personnel qualified for the application.

Pharmaceutical Powder Weighing

Pharmaceutical laboratories are one of the principal environments for XPert Filtered Balance Systems.

Opening containers, scooping powders, transferring active compounds, and weighing samples can all release fine airborne particles.

The XPert creates localized containment around these procedures while maintaining conditions intended to remain compatible with precision weighing.

Its 4-foot width can be especially useful in formulation, analytical development, and quality-control laboratories that require additional working space around the balance.

Active Pharmaceutical Ingredient Handling

Potent active pharmaceutical ingredients may require strict control of occupational exposure.

The XPert 3950402 can form part of a containment strategy for appropriate API weighing and transfer procedures.

Suitability should be determined through a compound-specific risk assessment that considers potency, occupational exposure limits, quantity handled, particle characteristics, frequency of use, and the facility's required containment level.

The Guardian 1000 provides an additional operational safeguard by continuously displaying face velocity and warning personnel if airflow falls outside the intended range.

Analytical Balance Applications

The XPert is specifically designed to accommodate analytical balances.

Its deep interior provides sufficient space for many balance platforms while leaving room for sample transfer and preparation.

Controlled airflow, aerodynamic containment features, and vibration isolation help reduce conditions that could negatively affect balance readings.

The laboratory should still verify measurement stability under actual operating conditions, particularly for high-resolution analytical work.

Microbalance Applications

The interior can also accommodate many microbalances.

Microbalances are especially sensitive to vibration, air movement, static electricity, temperature gradients, and operator technique.

Labconco's low-disturbance airflow design and vibration-isolated blower help address several of these concerns.

For extremely high-resolution weighing, laboratories should validate balance performance within the enclosure before establishing routine analytical procedures.

Precision Balance Applications

Precision balances are another natural fit for the XPert 3950402.

These instruments generally tolerate airflow more readily than microbalances while still benefiting from localized powder containment.

The large 4-foot interior allows the laboratory to establish a complete weighing station with room for samples, containers, and transfer tools.

Dry Chemical Handling

Chemical and industrial laboratories can use the XPert for compatible dry chemical weighing and transfer.

Powdered reagents, pigments, catalysts, standards, and fine chemicals may become airborne during normal handling.

Capturing these particles at the point of use helps reduce contamination of surrounding laboratory surfaces and personnel exposure.

Materials that release hazardous vapors require additional evaluation because HEPA filtration alone does not remove gases.

Mold and Asbestos Weighing

Labconco identifies mold and asbestos weighing among the particulate applications appropriate for XPert Filtered Balance Systems.

These materials can generate fine airborne particles that should be contained during sample preparation and weighing.

The enclosure's HEPA filtration and inward airflow provide a localized containment strategy for suitable laboratory procedures.

Facility-specific safety protocols should still govern handling, decontamination, and waste disposal.

Environmental Laboratory Applications

Environmental laboratories frequently weigh filters, soils, sediments, dust, dried residues, and other particulate samples.

Handling these materials can release dust into the surrounding laboratory.

The XPert provides a dedicated area for gravimetric and sample-preparation procedures while helping protect personnel and limit contamination of the laboratory environment.

Quality-Control Applications

Quality-control laboratories may perform hundreds of repetitive weighing procedures using powdered raw materials, intermediates, or finished products.

A dedicated filtered balance system provides a consistent containment environment for these operations.

The Guardian 1000 Digital Airflow Monitor also allows operators to verify face velocity before or during each procedure.

XPert 3950402 vs. XPert 3950400

Catalog numbers within the XPert family identify important configuration differences.

The 3950402 is the 4-foot, 115 V Filtered Balance System equipped with the Guardian 1000 Digital Airflow Monitor.

Versions without a built-in airflow monitor or with a different Guardian monitor should not be assumed to have the same monitoring capabilities.

Including the exact catalog number when purchasing used XPert equipment helps ensure the laboratory receives the intended configuration.

XPert Filtered Balance System vs. XPert Balance Enclosure

The difference between these two Labconco product families is important.

The XPert 3950402 Filtered Balance System includes its own blower and exhaust HEPA filter.

An XPert Balance Enclosure, such as models in the 3930 series, requires an external exhaust source such as building exhaust, a remote blower, or a compatible FilterMate.

The 3950402 is therefore a more self-contained solution for particulate weighing applications.

XPert vs. Conventional Chemical Fume Hood

A conventional chemical fume hood is primarily designed to contain chemical gases and vapors and usually exhausts air outside the building.

The XPert 3950402 is optimized for powder and particulate containment.

Its lower-disturbance airflow, smaller sash opening, deep balance-compatible interior, and vibration-isolated blower make it particularly well suited to weighing procedures.

When hazardous gases or substantial chemical vapors are generated, an appropriate chemical fume hood or other containment system may be required.

XPert vs. Biosafety Cabinet

The XPert 3950402 is not a Class II biological safety cabinet.

A biosafety cabinet uses specifically engineered HEPA-filtered airflow patterns for biological containment and, in Class II systems, also provides product protection.

The XPert is primarily designed to protect personnel during weighing and handling of powders and particulates.

Laboratories should select containment equipment according to the actual biological, chemical, or particulate hazard involved.

Recirculating HEPA-Filtered Operation

For appropriate particulate applications, the XPert returns HEPA-filtered exhaust air to the laboratory.

This eliminates the need to install external ductwork and avoids continuously exhausting conditioned laboratory air outdoors.

Installation can therefore be significantly simpler than adding a hard-ducted containment hood.

Recirculation should only be used when HEPA filtration is appropriate for all contaminants generated by the procedure.

Optional Outside Exhaust

XPert Filtered Balance Systems can also be configured for outside exhaust using appropriate accessories.

This may be useful when facility policies require external discharge or when the application benefits from exhausting filtered air outside rather than returning it to the room.

Any external exhaust configuration should be designed and balanced according to Labconco recommendations and facility requirements.

Work Surface and Supporting Base

The XPert 3950402 requires an appropriate work surface and supporting base.

Labconco offers compatible dished epoxy and other work-surface configurations along with supporting cabinets and stands.

A stable, level surface is particularly important when an analytical or microbalance is installed.

Because used equipment configurations vary, customers should confirm exactly which work surface, stand, cabinet, and accessories are included with this American Instrument Exchange unit.

HEPA Filter Maintenance

HEPA filter life depends on the type and quantity of particulate material handled, operating hours, loading rate, and laboratory procedures.

As filters load, airflow resistance increases.

The blower speed control and airflow-monitoring system help laboratories maintain appropriate operating conditions, but HEPA filters eventually require replacement.

Filters exposed to hazardous materials should be treated as contaminated components and replaced using appropriate containment procedures.

Proper Equipment Placement

Balances should be positioned sufficiently inside the enclosure while maintaining clearance from the rear baffle.

Containers and instruments should not block the Clean-Sweep airfoil at the front of the enclosure.

Avoiding unnecessary clutter helps preserve the designed airflow pattern and makes routine cleaning easier.

The 4-foot model provides substantial working room, but the additional space should not be treated as storage during hazardous procedures.
