24" Wide Vented Balance Enclosure Overview
The 24" Wide Vented Balance Enclosure (model VBE204) from Yamato Scientific is a self-contained PCR-grade balance enclosure built for weighing fine powders, chemicals, and biological products. Available through LabSupplies.com, authorized dealer, this unit measures 24" wide and provides a 24" × 23" × 21.5" interior work chamber. Top-mounted HEPA/blower filtration recirculates chamber air through an H14 filter back to the lab.
Optically clear 3/8" jeweled acrylic plastic forms the chamber, delivering superior chemical resistance and clear visibility. A phenolic base stabilizes analytical balances, dampens vibration, and carries a black finish that makes spilled powder easy to detect. Curved ABS airfoils route gentle, unobstructed flow through rear and side baffles toward the top-mounted HEPA filter.
Power options cover 115V (VBE204) and 220V (VBE214), letting facilities match available site circuits. Exterior dimensions of 26" × 26.75" × 41" and a 250 lb shipping weight define the footprint for bench and floor planning. Manufactured in the USA, this enclosure carries CE certification with a Declaration of Conformity.
Key Features
- Top-mounted HEPA/blower filtration: aluminum-frame H14 HEPA with 100 mm pleat, rated 99.9997% at 0.3 microns, sealed by upstream/downstream polyurethane gaskets.
- Face-velocity airflow alarm: 40–2000 fpm range with under 1-second response, LED and audible Piezo, plus green (healthy), yellow (turbulence), and red (system failure) indicators.
- Optically clear construction: 3/8" jeweled acrylic chamber pairs with a phenolic base for superior chemical resistance and low-vibration balance stabilization.
- Front viewing sash: multiple air foils improve containment and deflect drafts during weighing.
- Adjustable draft protection: front draft control protects fine-powder and sensitive sample readings.
- Configurable ports: electrical cord outlet port plus a side blank plate ready for an optional Bag-In/Bag-Out port.
How to Choose the Right Vented Balance Enclosure
Selecting a balance enclosure starts with the work you place inside it and the power and space your lab can supply. Match the following axes to your weighing protocol before ordering.
- Interior work area: confirm the chamber accommodates your balance, samples, and tools — this unit offers a 24" × 23" × 21.5" interior.
- Filtration class: H14 HEPA filtration captures fine particulates at 99.9997% efficiency, important for powders and biological products handled at the bench.
- Voltage: select 115V (VBE204) or 220V (VBE214) to match your facility's circuits and avoid step-up transformers.
- Footprint: verify the 26" × 26.75" × 41" exterior fits the intended bench or floor location.
- Containment and monitoring: a face-velocity alarm with LED and audible alerts confirms protective airflow during operation.
- Base material: a phenolic base resists chemicals and stabilizes analytical balances against vibration.

Frequently Asked Questions
What are the interior dimensions of the VBE204 balance enclosure?
The interior work chamber measures 24" × 23" × 21.5" (609 × 584 × 546 mm). Exterior dimensions are 26" × 26.75" × 41" (660 × 679 × 1041 mm), and the unit ships at 250 lbs.
What voltage options are available?
Two voltage versions are offered: the VBE204 runs on 115–120V, and the VBE214 runs on 220–240V. Both share identical construction, dimensions, and filtration — choose the model that matches your site power.
What type of filtration does this enclosure use?
It uses a top-mounted HEPA/blower system with an aluminum-frame H14 HEPA filter, 100 mm pleat, rated 99.9997% at 0.3 microns. Sealed polyurethane gaskets sit upstream and downstream, and filtered air recirculates back into the lab.
What materials are used in construction?
The chamber is optically clear 3/8" jeweled acrylic plastic with superior chemical resistance and clear visibility. A phenolic base provides chemical resistance, analytical-balance stabilization, low vibration, and a black finish that makes spilled powder easy to detect.
Does the enclosure monitor airflow during use?
Yes. A face-velocity alarm covers a 40–2000 fpm range with under 1-second response and combines LED and audible Piezo alerts. Green signals healthy airflow, yellow indicates turbulence, and red flags a system failure.
What is the difference between the VBE204 and VBE214?
Voltage is the only difference. The VBE204 is the 115V model and the VBE214 is the 220V model. Both offer the same 24" width, interior chamber, H14 HEPA filtration, acrylic construction, and phenolic base.
