Erlenmeyer flask, FEP, grad., 250 ml with ETFE-screw closure dia. 38mm

The excellent chemical resistance of PTFE FEP is combined here with a practical screw cap. Unbreakable, almost transparent, non-contaminating and resistant to almost all chemicals. The flasks are temperature resistant from -270°C to + 205°C and the closures from - 100°C to +150°C. Can be repeatedly sterilised in autoclaves and with all chemical methods. Before autoclaving, unscrew the cap and place it loosely on the neck of the flask. Suitable for all organic solvents and strong oxidising agents. Can be boiled in conc. nitric acid for trace element analyses. Autoclavable
