All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:
The Vacuum Chamber is empty.
The Vacuum Chamber and other system components are clean and dry.
The System is being operated at Sea Level
The ambient temperature is 18°C +/- 2°C
All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
The specifications are not impacted by the properties of your product.
If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.
It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.

Mixing can greatly improve the degassing operation of almost all materials; it is a must for thicker materials like pastes and gels. With Abbess Instruments can help you to prevent the integration of air into your product by using a vacuum mixer. Vacuum mixing chambers can be used for a wide variety of material including, but not limited to: foods, herbs, papers, liquids, jells, powders, plastics resins, epoxies and many other parts and materials. In-vacuum capability allows a large quantity of material to be mixed and degassed for enhanced performance.
Whether you are mixing in a 5 gallon drum or a 55 gallon drum, we have mixers in a range of sizes. The power options range from manual hand rotary mixers to fully automated horsepower level mixers. We will work with you to assess what mixing system your material requires.
bench top sized vacuum chamber is designed to be a rugged production or
testing unit. Some of our customers find this to be a practical size
(11inch dia by 6, 12 or 20inch deep) for use in vacuum degassing small
batches of resins, epoxies,other liquids, or filling molds and other
containers under vacuum.
For research, testing or production. Some of our customers find this to be a practical size for use in vacuum degassing of liquids, plastics resins, and blood products. This chamber is also used for vacuum drying samples and other material processing where temperature and time are critical.
