BACOENG 2 Gallon Acrylic Vacuum Chamber - Clear Degassing Chamber

In this review of the BACOENG 2 Gallon Acrylic Vacuum Chamber the bottom line is simple: it is a compact, visible degassing solution for hobbyists and small labs who need a clear, reusable chamber for resin, silicone and epoxies. The acrylic lid offers 92% light transmittance so users can monitor bubbles and adjust timing, while the included liquid filled gauge and a professional 5 ft reinforced vacuum hose make hookup and monitoring straightforward. This review focuses on real use, strength of construction and the limits of an acrylic lid for solvent work.

Key Features

• 2 gallon capacity: A small footprint chamber sized at 9.6 in x 3 in x 8.5 in that fits benchtop setups and supports batches of casting resin, silicone and epoxy.
• Acrylic lid with high transparency: 92% light transmittance and a large clear window allow continuous visual monitoring of material defoaming.
• Durable silicone gasket: Provides a reusable seal designed for thousands of cycles so users can expect repeated use without replacement under normal conditions.
• Liquid filled vacuum gauge: Measures 0-30 inHg so you can track vacuum level precisely during degassing and avoid over- or under-pumping.
• 5 ft reinforced vacuum hose: Professional grade hose with swivel ends that resists deformation up to -29.92 inHg and connects directly to a 1/4 in SAE vacuum pump fitting.

Who It's For

This chamber is best for resin crafters, mold makers and small-scale labs who need a visible, compact degassing solution and who work with compatible materials such as most epoxies, silicones and casting resins. The clear acrylic lid makes it easy to watch the degassing process and fine tune vacuum times for small batches.

It is not for users who routinely work with stabilization resins, alcohols, acetone or acrylic monomers and polymers, because those solvents can chemically attack the acrylic lid and cause cracking. Also, anyone requiring high-temperature processing or heavy industrial throughput should consider a different chamber with a tempered glass lid or larger capacity.

Pros & Cons

Pros

• Clear acrylic lid offers excellent visibility to control degassing in real time.
• Included liquid filled gauge and reinforced 5 ft hose give a professional, reliable hookup to a vacuum pump.
• Silicone gasket and durable acrylic body are designed for many reuse cycles under proper conditions.

Cons

• Acrylic lid is vulnerable to certain solvents and customers reported cracking if incompatible chemicals are used.
• Some users reported mixed sealing performance, so expect to verify the gasket and fittings before critical batches.

Specifications

Our Verdict

The BACOENG 2 Gallon Acrylic Vacuum Chamber is a practical, visible degassing chamber for hobbyists and small labs who need a reliable way to remove bubbles from resin, silicone and epoxy. It delivers strong build quality, a professional hose and an accurate gauge, making it good value when used with compatible materials. Users working with aggressive solvents or needing heavy-duty thermal or chemical resistance should choose a different lid material.

Frequently Asked Questions

Can I use solvents like acetone or alcohol in this chamber?
No. The acrylic lid is not compatible with alcohol, acetone, stabilization resins or acrylic monomers because they can chemically react and crack the lid.

Will the included hose fit my vacuum pump?
Yes, the 5 ft reinforced hose connects directly to a 1/4 in SAE pump fitting and has swivel ends for easy installation.

How hot can materials be inside the chamber?
Keep the temperature of the medium inside the chamber below 212F to avoid damage to the acrylic components.
