Vacuum Containers

Also known as vacuum degassing chambers, these remove trapped air from mixtures such as paint and mold resins. The fittings on the hose contain a gasket that allows you to connect the hose to flared fittings.

Aluminum containers are lightweight, corrosion resistant, and good for general use.

18-8 stainless steel containers have excellent corrosion resistance and are commonly used in laboratories.

Soda-lime glass containers are clear, so the material inside is visible from all angles.

PVC containers are lightweight and resist corrosion from harsh solvents. Because they’re taller than other containers, they’re often used for applications that require wood stabilization.

Containers with a side-mount gauge allow you to see the material inside of them when looking from the top.

Glass lids resist corrosion. They’re primarily used to eliminate air bubbles in woodworking projects that use harsh chemicals, which would deteriorate plastic lids. Glass lids are less durable than acrylic lids.

Acrylic lids are more durable than glass lids. They’re commonly used to eliminate air bubbles in hard setting materials, such as silicone and polyurethane.

Replacement lids do not include hardware or seal.

Replacement manifold assemblies include a manifold, vacuum gauge, washer, O-ring, and hex nut.

Vacuum-Sealable Glass Jars

Also known as mason jars, these have a tin-plated lid that forms a vacuum seal when heated.

Amber jars are good for light-sensitive contents.

Sanitary Pressurized Liquid Dispensing Tanks

Store and dispense liquids in food, pharmaceutical, and beverage plants—these tanks attach to a compressed air source for use in sanitary environments. A dip tube draws liquid from the bottom of these tanks for dispensing and spraying. They’re made of 316L stainless steel for excellent corrosion resistance, and have an electropolished finish that prevents product buildup and bacterial growth. Connect them to valves, hose, and caps with quick-clamp sanitary tube fittings, which are easier to sanitize than threaded fittings. Tanks comply with ASME BPVC.VIII safety standards for pressure vessels.

Safety regulations restrict sales to the listed jurisdictions/areas.

Desiccators

Protect material from moisture by storing them in these desiccators. Create a vacuum using the tube connection.

You need both the desiccator and the cartridge, each sold separately. The cartridge has indicating desiccant that turns from blue to pink when maximum absorption is reached.

High-Vacuum Chambers

Analyze gases, test for leaks, and check the effects of high altitudes on electronic components with these chambers. They remove air and gases to create a space void of molecules.

Acrylic chambers are clear, so the material inside is visible from all angles. Acrylic releases air at a faster rate than steel, so these chambers cannot reach vacuum levels as high as those of stainless steel chambers.

Stainless steel chambers reach and maintain significantly higher vacuum levels than acrylic vacuum chambers, and they work at higher temperatures. They are more chemical resistant than acrylic chambers, making them appropriate for use with lab substances such as acetone and isopropyl alcohol.

Quick- and claw-clamp connections allow you to connect and disconnect components easily. The clamps join two flanged ends and a rubber O-ring. Quick-clamp connections are also known as ISO-KF; you'll need a ring and quick clamp to complete the connection. Claw-clamp connections are also known as ISO-K; they require a ring and multiple claw clamps to secure.

Flanged connections create a seal that is tighter than clamp connections. Also known as CF connections, the flanges have sharp edges that press into a copper gasket as you tighten the bolts. The tighter seal means chambers with flanged connections can reach a higher vacuum level than chambers with clamp connections. Choose flanged connections for applications that require ultra-high vacuum, such as surface analysis experiments.

Maximum vacuum is measured in torr. The lower the torr value, the higher the level of vacuum.
