The standard semi-prep. degassing chamber was designed to be easy to prime, and is configured with a Teflon® AF degassing membrane (tubing) to provide maximum degassing capacity with the absolute minimum internal volume (<3% of PTFE designs with comparable degassing capacity) and a chemically inert, metal free flow path. Degassed mobile phase is available in three minutes or less!

B. The standard prep scale chambers are not recommended for GPC applications or for use with HFIP (hexafluoroisopropanol).
C. The flow rates given are for a gradient mixture of 60/40 MeOH/H2O, with a typical low pressure gradient mixing valve.
Higher flow rates are possible with high pressure mixing.
D. Estimated tubing pressure per unit change in flow assuming laminar flow with a viscosity of 1,0 cP
