Page 6: Features
Intended Use Operating range Gases that have dissolved into the solvent can cause bubbles in pumps and detectors. Good chromatographic separation therefore requires degassing the solvent.

Page 7: Eluents
Intended Use ® Thanks to the molecular structure of the Teflon AF membrane, only a very small surface is required for degassing the solvent. Thus the risk of carryover during a solvent change is reduced. The special pump design makes it possible to flush the pump head with a small blast of air, to remove solvent fumes, which could escape from the vacuum chamber. -
