Labconco XPert 3930230 2' Vented Balance Enclosure

The Labconco XPert 3930230 is a compact 2-foot vented balance enclosure designed to protect laboratory personnel during weighing, transfer, and handling of powders, particulates, and other potentially hazardous materials. Available used and refurbished from American Instrument Exchange, this specialized laboratory enclosure provides a controlled workspace for analytical balances, microbalances, and precision weighing applications where airborne contamination and operator exposure are important concerns.

Unlike a conventional chemical fume hood, the XPert Balance Enclosure is engineered specifically for laboratory weighing procedures. Its specialized airflow design helps direct airborne particles away from the operator while providing a relatively spacious interior for analytical instruments and sample preparation equipment.

The XPert 3930230 measures approximately 24" W × 29" D × 32" H, making it particularly suitable for laboratories with limited bench space. The enclosure can be connected to an external exhaust system or paired with a compatible Labconco FilterMate Portable Exhauster, allowing laboratories to select an exhaust configuration appropriate for their facility and application.

Designed for Precision Weighing and Powder Containment

Precision weighing presents unique challenges when laboratory personnel are handling fine powders, dry chemicals, pharmaceutical ingredients, or other materials that can become airborne during sample preparation.

Opening containers, transferring powders, using spatulas, and placing samples onto weighing vessels can release particles into the surrounding laboratory environment. These particles may present an inhalation hazard or contaminate nearby equipment and work surfaces.

The Labconco XPert 3930230 provides a dedicated containment area for these procedures. Controlled inward airflow helps capture airborne contaminants and direct them toward the enclosure's exhaust connection rather than allowing them to escape into the operator's breathing zone.

Its specialized design makes it particularly valuable for pharmaceutical formulation, analytical chemistry, environmental testing, and research laboratories where precision weighing and personnel protection must be addressed together.

Clean-Sweep Airflow and Containment Design

The XPert Balance Enclosure incorporates several airflow-management features intended to improve containment during weighing operations.

Labconco's Clean-Sweep front air foil allows incoming air to move across the work surface, helping carry airborne particles toward the rear of the enclosure. A zone-perforated rear baffle distributes airflow through the work area and promotes controlled horizontal movement toward the exhaust system.

Additional features include side-entry air foils, an upper containment sash foil, and an upper dilution air supply. These components work together to reduce stagnant airflow regions and help direct airborne contaminants away from the operator.

Because analytical balances can be sensitive to drafts and vibration, the XPert's purpose-designed airflow arrangement offers advantages over attempting precision powder weighing in a conventional laboratory fume hood.

Actual containment performance depends on the installed exhaust system, operating airflow, and laboratory procedures.

Compact Design for Analytical and Microbalances

With a nominal width of just 24 inches, the XPert 3930230 provides a compact alternative to larger laboratory containment enclosures.

Its approximately 29-inch exterior depth allows the enclosure to accommodate many analytical and microbalances while providing space for weighing vessels, sample containers, spatulas, and other accessories used during sample preparation.

The relatively low-profile design also makes the XPert attractive for laboratories with limited vertical clearance or existing benchtop equipment layouts.

For optimal weighing performance, the enclosure should be installed on a rigid, level, vibration-resistant supporting surface. Laboratories should also verify that the dimensions of their intended balance and accessories are compatible with the available interior workspace.

Flexible Exhaust Options

One of the advantages of the Labconco XPert Balance Enclosure is its flexibility in exhaust configuration.

The enclosure can be connected to an appropriately designed external exhaust system, allowing contaminated air to be removed from the laboratory through ductwork.

Alternatively, compatible XPert configurations can be paired with a Labconco FilterMate Portable Exhauster. Depending on the selected filtration media, the FilterMate system may provide HEPA filtration for particulates, activated carbon filtration for compatible chemical vapors, or a combination of both.

This flexibility can help laboratories select an installation appropriate for the materials being handled and the existing building ventilation infrastructure.

The XPert 3930230 does not include an integrated blower or built-in HEPA filtration. A remote blower or compatible FilterMate Portable Exhauster is required, and the appropriate equipment must be selected separately.

Powder Weighing and Pharmaceutical Applications

The XPert 3930230 is particularly well suited for pharmaceutical and analytical laboratory procedures involving small quantities of powders or other airborne particulates.

Potential applications include pharmaceutical ingredient weighing, powdered reagent preparation, analytical sample preparation, dry chemical handling, environmental sample processing, formulation research, and laboratory quality control testing.

Its compact footprint makes it practical for facilities establishing individual weighing stations or adding localized containment to an existing analytical laboratory.

The suitability of the enclosure for any particular compound should be determined through an appropriate risk assessment, including consideration of the material's toxicity, physical properties, quantities handled, and selected exhaust or filtration system.

Ideal Laboratory Environments

The Labconco XPert 3930230 is well suited for pharmaceutical research and development laboratories, analytical chemistry laboratories, biotechnology facilities, environmental testing laboratories, industrial quality control departments, university research facilities, and other laboratories requiring contained powder weighing.

It may be particularly attractive for facilities that need a dedicated weighing enclosure but lack the space for a larger chemical fume hood or full-size containment workstation.

Choosing a Vented Balance Enclosure vs. a Filtered Balance System

Labconco offers several types of XPert balance containment equipment, and understanding the differences is important when selecting the appropriate workstation.

The XPert 3930230 is a vented balance enclosure. It provides the physical containment workspace and specialized airflow design but requires an external exhaust source.

By comparison, certain XPert Filtered Balance Systems incorporate a blower and HEPA filtration directly into the enclosure, allowing filtered air to be returned to the laboratory for appropriate particulate applications.

The vented XPert configuration offers greater flexibility in exhaust design and may be particularly attractive for laboratories that already have suitable exhaust infrastructure or prefer to select a separate filtration system.

Installation and Exhaust Requirements

Proper installation is essential for effective containment and reliable balance operation.

The XPert 3930230 requires connection to a compatible remote blower or FilterMate Portable Exhauster. The selected system must provide the airflow necessary for the enclosure while accounting for duct resistance, filter loading, and other installation-specific factors.

Laboratories should also consider the supporting work surface, available bench space, and vibration isolation. Analytical balances may require a specialized balance table or vibration-resistant platform to maintain measurement stability.

After installation, the complete enclosure and exhaust system should be evaluated to verify appropriate airflow and containment performance before hazardous materials are handled.

Refurbishment and Testing

This Labconco XPert 3930230 is inspected and refurbished by American Instrument Exchange before shipment.

Our technicians inspect the enclosure's structural condition, sash, baffles, airflow components, and other applicable features to identify damage or missing components. The unit is cleaned and prepared for shipment following the appropriate inspection and refurbishment procedures.

Because the enclosure requires a separate exhaust source, final airflow performance must be established after installation with the selected blower or filtered exhauster.
