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.

WELCH - DuoSeal VACUUM PUMPS
Bypass feature produces higher vacuum at lower RPM. Carries off the last portion of gas and confines excess oil and volatiles to the exhaust side of each stage, leaving less contamination on the other side. Low speed operation reduces the rate of friction and wear on parts so pumps require less maintenance. Gas ballast valves for condensation prevention and removal of contaminates. Large oil capacity absorbs greater amounts of contamination. Single-stage pump 1399B-01 is recommended for continuous duty. All are mounted on a rugged steel frame and include V-belts, pulleys, belt guard, oil supply and instructions. Wired for 115V/230V, 60 Hz, Single Phase. Cord with North American plug and in-line switch provided with motors of 1 H.P. and below. Motors over 1 H.P. require conduit wiring.

WELCH - Dry pumps
Standard Lab Duty - Oil-Free High Throughput - Oil-Free

Non-Corrosive Duty
• Degassing
• Cell harvesting
• Centrifuge
• Filtration
• Aspiration
• Drying

Welch Dry Pumps provide a steady vacuum, unaffected by opening another faucet (water aspirators) or stopcock (house vacuum). There is no contaminated waste water to contend with and no oil maintainence required. Pumps meet or exceed the performance of water aspirators and house vacuum. Applications include vacuum filtration, rotary evaporation, aspiration, degassing and desiccating.

STANDARD DUTY PUMPS, constructed of aluminum and powered by an economical WOB-L® piston with Teflon® seal, should only be used to draw air or water vapor. Supplied with vacuum/pressure regulators and guages, water trap and muffler.

Pricing is valid only for USA and Canada. All prices are in U.S. dollars..

Powered By An Economical WOB-L Piston
Simplicity is the key to the economical aluminum design. As piston wobbles, air resistance on upward stroke expands Teflon seal on piston to increase its efficiency while compensating for the wobble action.

Theoretical Hena Pumpdown Curves
 
NOTE: These curves are for perfectly dry, empty, clean chambers at sea level as outlined in the Performance Specifications Side Bar. In reality, these curves will be adversely affected by, if nothing else, outgassing of customer’s product (and inadequate cleaning and preconditioning). As a consequence, Abbess 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.
