Stainless Steel Degassing Chamber

What is the Stainless Steel Degassing Chamber?

A stainless steel degassing chamber removes dissolved gases from liquids, resins and slurries under moderate vacuum. It is used in electronics, adhesives and analytical sample preparation where bubbles cause defects or errors.

Overview

The degassing chamber is a stainless steel vessel with a hinged or clamped lid, a vacuum port, a vent valve and often a gauge. Volumes range from 10 to 200 liters to suit beakers, cartridges, molds and small tanks. Working vacuum is typically 50 to 1 mbar, reached quickly with a two-stage pump. Gentle heating, through a jacket or a heated base, lowers viscosity and speeds gas release, while a slow vent prevents re-dissolution and foaming. Some chambers include a rotating or vibrating platform to help bubbles escape from viscous media, and a transparent lid for observation. Wetted surfaces are usually 304 or 316 stainless steel for compatibility with water-based, solvent and resin systems. Applications include preparing epoxy and silicone, degassing potting compounds and removing dissolved oxygen from analytical reagents.

How does it work?

A vacuum chamber provides the sealed volume from which a pump removes gas. Its walls and seals must resist the pressure difference, which at full vacuum is about one bar acting inward on every square centimeter. Chamber materials, usually stainless steel, aluminum, acrylic or glass, determine strength, chemical resistance and outgassing behavior. Seals in O-ring grooves, gaskets or flat flanges keep air out, and the sealing method sets the achievable vacuum and the ease of opening. Ports allow connection to a pump, gauge, vent valve and feedthroughs for electrical, fluid or optical access. Internal features such as shelves, heating platens, electrodes or sample holders adapt the chamber to its task. The pump-down rate depends on chamber volume, pump speed and the conductance of the connecting line, so the chamber and pump must be matched.

What are the key features?

• Stainless steel vessel with hinged or clamped lid
• Volumes of 10–200 L for beakers and molds
• Working vacuum of about 50–1 mbar
• Optional jacket or heated base for viscosity reduction
• Rotating or vibrating platform options
• Transparent lid option for process observation

What are the technical specifications?

A typical stainless steel degassing chamber configuration offers volume of 10–200 L, working vacuum of 50–1 mbar, material of Stainless steel 304 or 316, lid of Hinged or clamped, clear option, heating of Ambient to 80 °C optional and platform of Static, rotating or vibrating. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Stainless Steel Degassing Chamber is used in epoxy and silicone preparation, potting compound degassing, reagent dissolved gas removal, particle suspension degassing and adhesive and coating preparation. Across the wider Vacuum Chambers class, laboratories also deploy it for sample drying and desiccation, degassing of liquids and resins and vacuum coating and evaporation.

Which standards and certifications apply?

Relevant standards and methods include IEC 61010-1, ISO 21360, ISO 27893, ISO 9001 and GB 4793.1. Certification candidates for this model are CE, ISO 9001 manufacturing and PED compliance; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Never use a chamber above its rated pressure difference, and fit a relief valve or rupture disc where a pump could over-pressurize it or where a process generates gas. Keep sealing surfaces clean and free of scratches, and replace O-rings that are cut, swollen or hardened. Apply vacuum grease sparingly, because excess grease traps particles and can contaminate samples. Support heavy doors safely and check hinges and clamps regularly, especially on large chambers. Verify thermal uniformity if the chamber is heated, and use compatible feedthroughs for electrical or fluid lines. Follow IEC 61010-1 for associated electrical equipment and local pressure vessel rules where applicable. Record base pressure and leak-up rate during commissioning so changes can be detected later.

How do I select the right Stainless Steel Degassing Chamber?

Choose a stainless degassing chamber when bubbles must be removed from viscous or reactive media and cleaning matters. For gentle sample drying, a desiccator or oven is more suitable. In the RFQ, state volume, vacuum, heating, platform motion and material compatibility.

How does it compare with other Vacuum Chambers variants?

Start with the volume needed for your samples or components, and the pressure you must reach. A desiccator-style chamber works for storage and gentle drying at rough vacuum, while ovens and coating chambers need deeper vacuum and often heating or electrode feedthroughs. Choose the material for the process: stainless steel for strength, chemical resistance and cleanability; acrylic or glass for visibility and non-magnetic work; aluminum for light weight. Confirm the pressure rating with a safety factor and check whether a relief device is needed. Select the sealing method, typically an O-ring or gasket, for the vacuum level and opening frequency, and list the ports you need for pump, gauge, vent and feedthroughs. Consider internal fixtures, door or lid access, window size and how the chamber will be cleaned and mounted.
