Labconco XPert 3950200 2' Filtered Balance System – Used and Refurbished
The Labconco XPert 3950200 Filtered Balance System is a compact 2-foot powder containment enclosure designed to provide personnel protection during weighing, transfer, and manipulation of powders and other potentially hazardous particulates. Featuring an integral blower and 99.99% efficient HEPA exhaust filtration, the XPert creates inward airflow through the front opening to help contain airborne particles generated during laboratory procedures.
Unlike a conventional externally ducted balance enclosure, the XPert 3950200 incorporates its motorized impeller and HEPA filtration system directly into the enclosure. Contaminated air is drawn away from the operator, passed through the HEPA filter, and discharged as filtered air from the top of the system. This allows HEPA-filtered exhaust to be returned to the laboratory for appropriate particulate applications, eliminating the need for a separate exhaust system.
The 2-foot configuration is particularly useful when laboratory space is limited or when procedures involve microbalances, analytical balances, precision balances, or small-scale powder handling. A deep work area accommodates many laboratory balances while the enclosure's aerodynamic Clean-Sweep airfoil, upper containment sash foil, and zone-perforated rear baffle help promote effective containment.
Catalog number 3950200 is the 2-foot, 115 V version of the XPert Filtered Balance System without the optional Guardian airflow monitor. It operates at approximately 60 fpm face velocity with an exhaust volume of approximately 85 CFM.
This Labconco XPert 3950200 is used and refurbished by American Instrument Exchange. AIE technicians inspect and test the enclosure before shipment to verify blower operation, lighting, controls, sash condition, airflow, and other installed functions. The enclosure is thoroughly cleaned and includes a 90-day warranty.

Overview
The Labconco XPert Filtered Balance System was developed specifically for laboratory procedures where weighing or manipulating powders can generate airborne particulates.
Conventional laboratory balances generally require an open weighing area. When hazardous, potent, irritating, or otherwise undesirable powders are transferred onto the weighing pan, small particles can become airborne and enter the operator's breathing zone.
The XPert addresses this problem by surrounding the balance with an aerodynamically designed containment enclosure.
An integral blower creates inward airflow through the front opening. Airborne particulates generated inside the enclosure are carried away from the operator and toward the rear baffle before passing through the HEPA filtration system.
Filtered air can then be returned to the laboratory for appropriate applications.
Common Applications
The Labconco XPert 3950200 is well suited to pharmaceutical powder weighing, active pharmaceutical ingredient handling, chemical weighing, toxic powder containment, research-compound preparation, dry chemical transfer, analytical sample preparation, environmental sample weighing, quality-control procedures, nanoparticle research involving appropriately filterable particulates, and other small-scale laboratory procedures where airborne powder containment is required.
It can also provide a useful controlled environment for weighing standards, powdered reagents, pigments, fine chemicals, and other materials that may become airborne during transfer.
The XPert is designed primarily for particulate containment. Applications involving hazardous gases or chemical vapors require a containment system and filtration or exhaust configuration appropriate for those contaminants.
Ideal Laboratory Types
The XPert 3950200 is well suited to pharmaceutical research laboratories, biotechnology companies, analytical laboratories, chemical laboratories, environmental testing facilities, industrial quality-control laboratories, formulation laboratories, academic research institutions, contract research organizations, forensic laboratories, and other facilities that routinely weigh or transfer powders.
Its compact 2-foot footprint is especially useful in laboratories where bench space is limited.

Powder and Particulate Containment
The primary purpose of the XPert 3950200 is to reduce operator exposure to airborne powders and particulates during laboratory procedures.
Room air enters through the front opening and moves across the work area toward the enclosure's rear baffle.
This inward airflow helps keep particles generated inside the enclosure from escaping into the operator's breathing zone.
Contaminated air then passes through the exhaust HEPA filter before leaving the enclosure.
For appropriate particulate applications, HEPA-filtered exhaust can be returned directly to the laboratory.
Built-In HEPA Filtration
The XPert Filtered Balance System uses a single exhaust HEPA filter rated at least 99.99% efficient for particles 0.3 micron in diameter.
HEPA filtration is particularly effective for containment of airborne particulate matter.
This makes the XPert useful for powders, dry chemicals, pharmaceutical compounds, and other particulate-generating procedures when the contaminants involved are appropriate for HEPA filtration.
HEPA filtration should not be confused with chemical-vapor filtration. Gases and vapors require an appropriate chemical filtration or external exhaust strategy.
Integral Blower System
One advantage of the XPert Filtered Balance System is that the blower is integrated directly into the enclosure.
A separate remote exhaust blower is therefore unnecessary for normal recirculating HEPA-filtered operation.
The motorized impeller draws room air through the sash opening and moves contaminated air through the HEPA filter.
Integrating the blower and filter into the enclosure simplifies installation and reduces the amount of additional mechanical equipment required.
Isolation Supports and Balance Stability
Containment airflow and blower vibration are important considerations when placing a sensitive analytical balance inside an enclosure.
Labconco designed the XPert Filtered Balance System with isolation supports intended to minimize transmission of blower vibration into the work area.
This is particularly important when using analytical or precision balances capable of detecting very small changes in mass.
The suitability of a particular balance should still be evaluated under actual operating conditions, especially when very high readability is required.
Deep Balance Work Area
The XPert 3950200 provides approximately 23.4 inches of interior depth.
This relatively deep work area was designed to accommodate many micro, analytical, and precision laboratory balances while maintaining sufficient room for sample containers and weighing accessories.
The approximately 21.6-inch interior width provides a compact but functional weighing area within the enclosure's 24-inch overall width.
60 FPM Face Velocity
American Instrument Exchange lists the XPert 3950200 for operation at approximately 60 feet per minute face velocity.
This relatively low airflow is particularly important in a balance enclosure.
Excessive air velocity can create turbulence around a balance pan and negatively affect weighing stability.
The XPert's containment geometry is designed to achieve effective particulate capture without requiring the substantially higher airflow rates associated with many conventional laboratory fume hoods.
85 CFM Exhaust Volume
The 2-foot XPert 3950200 operates at an exhaust volume of approximately 85 cubic feet per minute.
The relatively low exhaust volume contributes to the enclosure's suitability for precision weighing and also reduces the amount of room air that must be moved through the system.
Because the HEPA-filtered exhaust can be returned to the laboratory for appropriate applications, the system does not necessarily require the building to replace 85 CFM of exhausted conditioned air continuously.
Clean-Sweep Airfoil
Labconco's Clean-Sweep airfoil is designed to promote smooth airflow into the enclosure.
A conventional sharp front edge can generate turbulence as room air enters the work area.
The aerodynamic airfoil helps guide air smoothly through the front opening and reduces disruptive eddies near the operator.
The airfoil should remain unobstructed during use so that the enclosure can maintain its intended airflow pattern.
Upper Containment Sash Foil
The upper containment sash foil helps direct airflow inward near the upper edge of the work opening.
Air movement around a laboratory enclosure can be influenced by operator motion, room ventilation, nearby doors, and other environmental conditions.
The sash foil is part of the XPert's overall aerodynamic design intended to maintain containment across the front opening.
Zone-Perforated Rear Baffle
The zone-perforated rear baffle helps distribute airflow across the width and height of the enclosure.
Rather than drawing contaminated air toward one small exhaust point, the baffle encourages particles to move toward the rear of the work area across a broader surface.
This helps reduce stagnant areas and promotes effective contaminant capture.
Equipment and containers should be positioned so they do not unnecessarily obstruct the rear baffle.
Bag-In/Bag-Out HEPA Filter Disposal
The XPert incorporates a bag-in/bag-out system for HEPA filter removal.
This feature is particularly useful when the filter may contain hazardous or potent particulate material.
Rather than requiring technicians to handle a contaminated filter openly, the disposal system is designed to allow the filter to be contained during removal.
Laboratories should establish filter-change procedures appropriate for the materials that have been handled inside the enclosure.
Pharmaceutical Powder Weighing
Pharmaceutical research and manufacturing laboratories frequently need to weigh potent or biologically active powdered compounds.
Even small transfers can release fine particles into the air.
A filtered balance enclosure provides localized containment at the point where the powder is handled.
The compact XPert 3950200 can therefore be useful for small-scale formulation, pharmaceutical research, quality-control testing, and analytical sample preparation involving appropriate particulate materials.
Active Pharmaceutical Ingredient Handling
Active pharmaceutical ingredients may require enhanced containment because very small quantities can have significant biological activity.
The XPert provides inward airflow and HEPA filtration to help contain appropriately filterable API powders during weighing and transfer.
The suitability of the enclosure for a particular compound should be determined through the laboratory's risk assessment, including consideration of potency, occupational exposure limits, quantity handled, physical form, and the complete containment strategy.
Analytical Balance Applications
The XPert 3950200 was specifically designed to accommodate sensitive laboratory balances.
Its deep interior allows many analytical balances to fit inside the enclosure while leaving working room for containers and samples.
Low airflow, aerodynamic containment features, and blower isolation help reduce conditions that could interfere with weighing.
Laboratories performing very high-resolution measurements should verify balance stability under actual operating conditions before adopting a routine method.
Precision Balance Applications
Precision balances can also be used inside the XPert for appropriate powder-handling procedures.
These instruments generally tolerate airflow more readily than high-resolution analytical or microbalances while still benefiting from the operator protection provided by a containment enclosure.
The 2-foot configuration can provide a particularly efficient workstation when only a balance and small amount of supporting labware are required.
Chemical Powder Handling
The XPert can also support weighing and transfer of compatible dry chemicals.
Fine powdered reagents can become airborne when containers are opened, scoops are used, or material is transferred onto weighing paper or vessels.
Performing these procedures inside a filtered balance enclosure helps capture airborne particles near their source.
If the chemical also produces hazardous vapors, HEPA filtration alone may not provide appropriate protection.
Environmental and Analytical Laboratories
Environmental laboratories frequently weigh dried soil, dust, filters, powders, reference materials, and other particulate samples.
Some of these materials can generate nuisance or potentially hazardous airborne particles during transfer.
The XPert can provide a dedicated containment area for these procedures while retaining the precision needed for gravimetric analysis.
Forensic Laboratory Applications
Forensic laboratories may also perform weighing and transfer procedures involving powders or unknown particulate evidence.
A filtered balance enclosure can provide localized containment during appropriate analytical procedures.
The enclosure selected for forensic work should be consistent with the laboratory's evidence-handling requirements, contamination-control procedures, and hazard assessment.
XPert Filtered Balance System vs. Standard Balance Enclosure
Labconco manufactured both filtered XPert systems and enclosures intended for connection to separate exhaust equipment.
The XPert 3950200 is a complete Filtered Balance System with its own motorized impeller and HEPA exhaust filtration.
This means a separate FilterMate or building exhaust connection is not required for normal recirculating HEPA operation.
That distinction can simplify installation substantially.
XPert Filtered Balance System vs. Chemical Fume Hood
A conventional chemical fume hood is primarily designed to capture gases, vapors, and other chemical contaminants and typically exhausts air outside the building.
The XPert 3950200 is optimized for low-airflow particulate containment during weighing and powder manipulation.
Its integral HEPA filter captures particles rather than chemical vapors.
A conventional chemical fume hood or another appropriately filtered system should be selected when gaseous contaminants are the primary hazard.
XPert Filtered Balance System vs. Biosafety Cabinet
The XPert should not be treated as a substitute for a biological safety cabinet.
Class II biosafety cabinets are specifically designed and tested for biological containment and incorporate airflow patterns appropriate for work with microbiological materials.
The XPert is a powder and particulate containment system designed around weighing and similar procedures.
The appropriate enclosure should always be selected according to the actual hazard.
XPert Filtered Balance System vs. Ductless Chemical Hood
A ductless chemical fume hood typically uses activated carbon or another chemical sorbent to capture gases and vapors.
The XPert 3950200 uses HEPA filtration for particulate containment.
This makes the two systems appropriate for different contaminant types.
When selecting between them, laboratories should determine whether the primary hazard is particulate matter, chemical vapor, or a combination requiring a different containment strategy.
Recirculating HEPA-Filtered Exhaust
For suitable applications, the XPert's HEPA-filtered exhaust can be returned directly to the laboratory.
This eliminates the need for permanent exhaust ductwork and allows the enclosure to operate as a relatively self-contained workstation.
Recirculation can also reduce the amount of conditioned laboratory air discharged outdoors compared with a hard-ducted containment device.
The materials being handled must be appropriate for HEPA filtration before recirculating operation is selected.
Optional External Exhaust
Although the XPert is designed for recirculating HEPA-filtered operation, filtered exhaust can also be directed outside when an appropriate canopy exhaust connection and remote blower configuration are used.
This gives laboratories additional flexibility when facility requirements call for externally discharged exhaust.
External exhaust components are not included with the standard American Instrument Exchange listing unless specifically stated.
No Built-In Airflow Monitor on Catalog No. 3950200
Catalog number is important when comparing XPert systems because different versions were supplied with different airflow-monitoring configurations.
The Labconco 3950200 does not include a built-in airflow monitor as part of its standard factory configuration.
The closely related 3950201 was supplied with a Guardian airflow monitor, while catalog number 3950202 used the Guardian 1000 Digital monitor.
This distinction helps buyers identify the exact XPert configuration they are purchasing.
Work Surface Requirements
The American Instrument Exchange listing specifies that the work surface is not included.
The enclosure therefore requires an appropriate supporting work surface or installation arrangement before use.
For balance applications, stability is particularly important.
A rigid, level, low-vibration surface helps maintain balance performance and provides a secure foundation for the enclosure.
Customers should confirm the physical configuration and included components of the individual AIE unit when planning installation.
HEPA Filter Replacement
HEPA filters accumulate particulate material over time and eventually require replacement.
Replacement frequency depends on the quantity and type of powders handled, operating hours, loading rate, and laboratory requirements.
Filters that have been exposed to hazardous materials should be treated as contaminated components.
The XPert's bag-in/bag-out design helps facilitate contained filter removal.
Proper Enclosure Setup
Good containment depends on more than simply turning on the blower.
Balances and other equipment should be positioned so they do not block the rear baffle or front airfoil.
Powder-handling procedures should generally be performed sufficiently inside the enclosure rather than directly at the front opening.
Strong room drafts, supply-air diffusers, open doors, and heavy traffic near the enclosure can also affect containment performance.
Refurbishment and Testing by American Instrument Exchange
American Instrument Exchange inspects and tests used filtered balance enclosures before shipment.
For the Labconco XPert 3950200, AIE technicians evaluate blower operation, airflow, lighting, controls, sash condition, HEPA filter housing, and other installed components. The enclosure is inspected for physical condition and accessible interior and exterior surfaces are thoroughly cleaned.
Because HEPA filter condition can depend on previous use and the intended application, customers should confirm the filtration configuration supplied with the individual unit and determine whether new filtration is required for their laboratory's procedures.
