The 2-channel degasser module provides outstanding performance through its use of a newly developed micro vacuum pump while taking up only a minimum of space. The gas diffusion rate has been improved by a factor of 200 – 300 times, thanks to a new amorphous fluoropolymer rather than a regular Teflon membrane. Excellent chemical and physical stability parameters, as well as the reduction of the internal chamber volume to less than 8 ml are convincing features. The semi-preparative KNAUER online degasser module can be used for flow rates of up to 50 ml/min.
