With our unique patent pending gasket design (Utility Patent #14/533,548) this shatter chamber is sure to last 10,000 uses with proper care and maintenance. The gasket itself is reversible (doubling the life of our system) allowing customers to instantly take it off and flip it over. No adhesives are used! Our simple gasket design even allows you to place the lid on the chamber somewhat off center and still pull a full vacuum. This is a feature that most other vacuum chambers do not offer. The maximum allowed temperature of this chamber is 160f. The components of this chamber are rated at higher temperatures however as a vacuum vessel we limit maximum operational temperature to 160f. Every chamber is tested prior to shipping to lose no more than 2.5Hg/24hrs.
