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.

Wobble Stick (Increased Automation/Manual Movements In Vacuum)
A wobble stick allows movement within a vacuum chamber. Most movements that would typically be done by hand can be done through a wobble stick. For example, in a vacuum under pressure, a wobble stick can move to press a button or rotate an object.
While linear actuators only allow movement along one of the three planes, a wobble stick can also introduce movement along all of the planes within an approximately 270-degree cone volume with a ball mechanism.
A wobble stick is purely mechanical, however it can be partnered with other accessories to gain maximum control over in vacuum processes. For example, a liquid feed-thru hose can be made more rigid when a rod is attached. This can also allow for more movement manipulation of the hose, rather than have it simply fall to the ground of the chamber.

Wobble sticks are available in a wide range of lengths, movement options, and specifications.
