Versatile Vacuum Chamber Systems
Precision Engineered for Laboratory, Research and High-Technology Applications
Essex Bay Engineering vacuum chambers are engineered for research laboratories and surface science applications, offering a robust, modular system for high vacuum and ultra-high vacuum environments. These systems include stainless steel bell jars, feedthrough collars, baseplates, and base wells — each designed for seamless integration and optimal performance.
Stainless Steel Bell Jars
These jars are designed for compatibility with Essex Bay Engineering baseplates, feedthrough collars, and base wells. A dovetail groove holds a FKM elastomer gasket to form a reliable vacuum seal. Each bell jar includes a 4 in (101.6 mm) view Pyrex® viewport and internal vacuum welds to ensure UHV compatibility. For ease of use, a welded hoist ring is included. Electropolished finishes are optional.
Feedthrough Collars
Used to expand system functionality, feedthrough collars offer radially oriented access ports in 4, 8, or 18 port configurations. Ports accept 2-3/4 in (69.9 mm) Essex Bay Engineering Conflat™ CF or ISO KF NW40 (40 mm) Kwik-Flange™ connections, supporting standard Essex Bay Engineering electrical, fluid, or motion feedthroughs. A compatible Essex Bay Engineering baseplate is required.
Baseplates
These provide the foundation for vacuum systems. Available for 12 in (304.8 mm), 18 in (457.2 mm), and 24 in (609.6 mm) diameter chambers. Interface options include ANSI ASA elastomer, Essex Bay Engineering Conflat™ CF, and Large-Flange™ ISO LF types. Baseplates mount directly to a vacuum pump or gate valve.
Base Wells
Combining the features of a baseplate and a feedthrough collar into a single unit, base wells reduce sealing surfaces by integrating a vacuum weld joint. Available with 4, 8, or 18 access ports, they offer the same flange options as the collars and baseplates. Gasket seals must be purchased separately.
