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.

Optimize your impregnating, encapsulating and dosing production processes with Abbess Instruments vacuum degassing and filling chambers. Abbess Instruments reduces your production failures and processing time by eliminating moisture issues, air bubbles, and air cavities, and by automation (through controlling your process variables). We can take your product, in-situ, all the way from evacuation through to its cured state.
Abbess has solutions for your filling needs that ranging from simple, manual operations to more automated operations. A basic solution, a two-chamber system, will allow you to convey degassed material from the secondary chamber to the item being dosed in the main chamber as the process cycle dictates. This manual system can be upgraded to a semi-automated system by adding a Vacuum Cycle Controller (VCC), which automates vacuum/hold/vent control functions via panel-mounted buttons and indicators.
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.
