Cold Finger

Getter Cold Finger Overview Abbess Instruments’ Cold Fingers are designed to augment HV and UHV vacuum chamber environments. Cold Fingers work to improve the overall Pumpdowns in vacuum chambers in both speed of Pumpdown as well as the ultimate vacuum level for the systems they are placed in. These elements are used to act as the cold element within the vacuum chamber and attract condensable volatiles within the environment. By attracting these condensable vapors to the cold finger, the overall … Read More

Thermal Shrouds in Vacuum Systems

The Abbess High Vacuum Thermal System allows items placed inside to be exposed to high vacuum pressure as well as extreme temperatures via the electrically heated and refrigerant cooled Thermal Shroud. This thermal vacuum chamber system is controlled by a Vacuum Cycle Controller (VCC), used to integrate temperature and vacuum level monitoring and automate many of the process control functions via panel-mounted indicators and activating buttons and switches, as well as a touch screen PC with a user-specific customized programming … Read More

High Vacuum System with Thermal Shroud

This 48 inch cube system allows items placed inside to be exposed to vacuum down to 10^-7 Torr. A Vacuum Cycle Controller (VCC) is used to automate control functions. The VCC enables system monitoring and control of the thermal vacuum chamber via touch screen buttons and graphic indications of sensor data registered and controlled by a PC with a user-specific Graphical User Interface (GUI). The system can be further customized to realize robust data logging capabilities. Unique Features: Heated/Cooled Thermal … Read More

Performance Specifications

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.
