Vacuum filter funnel, PTFE, Diaphragm diameter 47 mm, 125 ml, completely made of fluoroplastic (PTFE/PFA) - without sealing materials. The filter funnel, which is designed for normal or low pressure, is resistant to almost all chemicals and does not itself release trace elements to the medium to be filtered. The filter membrane can be changed easily by simply screwing on the Pro correcting device. The vacuum connection is a multi-stage olive with screw plug, adapted to the most common vacuum hoses. The NS 29/32 ground joint allows an absolutely tight connection to the round bottom flask made of PTFE or PFA, or to glass vessels with a NS 29/32 cut (please note vacuum suitability). The attached PTFE cover prevents contamination of the sample. Due to the anti-adhesive surface, fluoroplastic (PTFE/PFA) filter units are easy to clean and therefore have a long service life. (Delivered without filter membrane) for diaphragm diameter 47 mm, filter surface 13.8 cm², for hose diameters 6 and 8 mm, pretrigger volume 125 ml, outside diameter 62 mm, total height 188 mm
