guarantee a good mechanical and chemical resistance with a long service life.

The compatibility of the tube material with unknown gases has to be
checked before using.
A possible change of hoses is simplified by using specially designed hose sets. The tube connectors
DN4/6 allow as well the application of PTFE tube. The peristaltic pump SR25.1... is supplied with
electric mains for 230V/50Hz and 115V/60Hz.
