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.

Vacuum Mixing Options

Mixing can greatly improve the degassing operation of almost all materials; it is a must for thicker materials like pastes and gels.

Prevent the integration of air into your product by using a vacuum mixer.

Electric Mixer 5 gallon design and Vacuum Casting mixer

These Chambers are constructed of heavy alloy. Our customers find this to be a practical size for use in vacuum degassing and vacuum processing of all sorts of items including, but not limited to: foods, herbs, papers, liquids, jells, powders, plastics resins, epoxies and many other parts and materials. This chamber is also used in many industries where vacuum work is required

In vacuum heaters can be ordered with your chamber (round top loading chambers only).

All chambers are vacuum tested to 29.92 inches of Hg or better (10-6 torr ) and should maintain this for its life dependent on seal condition and customer use.

About Mixers

Use the following guidelines to select the right mixer for your needs:

  • Power Source— Mixers are powered either by air or electricity.
    Air-powered mixers have infinitely variable speed control, can't be overloaded, and, with proper lubrication, won't burn out.
    Electric mixers use energy more efficiently and thus are more economical than air-powered mixers.
  • Drive— Select the drive style that's right for your application.
    Direct-drive mixers turn the propeller at the same speed as the motor, offering high rotational speeds for quick mixing of low-viscosity materials.
    Gear-drive mixers typically turn the propeller at lower speeds than the motor, making them ideal for higher-viscosity materials.
  • Viscosity (centipoise) — The thickness, or resistance to flow, of a material. Viscosity is typically measured in centipoise, with water being equal to 1 and molasses to 15,000. Therefore, the greater the number, the higher the viscosity. Horsepower— Refer to the table below to find the approximate horsepower of the mixer you'll need. When in doubt, choose a motor with a higher horsepower to avoid overloading.
