Degassers

Range of sample preparation degassers


Consistent and reliable surface area results depend upon proper sample preparation procedures. In terms of BET 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.

XeriPrep Degasser

The gold-standard in sample preparation for physisorption analyzers. It provides PC control of all heating zones with individual heating ramps and times. The Built-in cold trap enable efficient removal of condensables at low degassing temperatures and for a clean vacuum. Turbo-pumped version available for rapid high-vacuum degassing.

MasterPrep Degasser

Vacuum/Flow preparation unit for Quadrasorb-SI and Autosorb-6B. Individually heated stations with programmable temperature ramp. Individual cooling stations. Connects to PC for easy setup and data logging. Vacuum pump and sample cells not included

FloVac Degasser/Flow Degasser

Recommended for all surface area analyzers. Six sample ports, single temperature zone: ideal for quality control and fixed protocol applications. Choose from flow/vacuum or flow-only models. Vacuum pump and sample cells not included.

Thermoflow Degasser

Flow-through preparation unit for Monosorb surface area analyzer. Each of three stations has independent temperature controls. Comes complete with heating mantles and sample cell assemblies.
