Consistent and reliable surface area results depend upon proper sample preparation procedures. In terms of B.E.T. analysis, the limiting
step in rate of throughput is often sample preparation. The complete degassing of samples can often require several hours, while surface
area measurements may require as little as 15 minutes.
Quantachrome manufactures several models of
degassers to fulfill your sample preparation needs. These
degassers provide a virtually
continuous supply of properly prepared samples for the QUADRASORB SI Surface Area and Pore Size Analyzer.

MasterPrep Autosorb Degasser Features Flow Degasser FloVac Degasser
The FloVac™ Degasser
The FloVac provides cost effective vacuum
degassing. Complete with single-zone
heater (to 400°C), digital temperature
controller and built-in digital vacuum
gauge. Each sample station has its own
adjustable evacuation/backfill rate control.
Flow degassing is also possible and can be
advantageous in removing large quantities
of moisture prior to vacuum degassing.
Individual cooling stations. Vacuum pump
not included.
Flow Degasser
The popular Flow Degasser has the
same heating and cooling features as
the FloVac but without vacuum
capability. Ideal for quality control
applications, teaching and start-up
labs. Each sample station has its own
adjustable flow rate control.
