BOLA Vario Couplings
SCREW JOINTS FOR HPLC
Material: Temperature resistance Chemical resistance: Pressure: autoclave:
PVDF from -30°C to +150°C ++ very good 3 bar 121°C
Product description:
Two-part coupling made of PVDF for connecting elastic tubing (e.g. Viton®, Tygon®, silicone) to hard-walled tubing made of PTFE, glass or other plastics. Easy and ingenious functioning: the elastic tubing is pushed on a cone and fixed on the coupling by means of a connecting nut. On the other side, the hard-walled tubing is connected as follows:
Flanged PTFE tubing with miniature connectors (e.g. Cat. No. F 740 page 299) is connected to a female thread UNF 1⁄4” 28 G.
Hard-walled tubing up to a maximum O.D. of 10 mm is connected to a GL thread by means of laboratory screw joints (see page 90). Restricted chemical resistance, working temperatures up to max. +150°C.
