Laboratory glassware: DURAN® flat flange round bottomed flask flange with groove, for vacuum use

Pressure and vacuum resistant due to the wall thickness and geometry. Groove for O-ring seal. Typical applications: reactions under pressure and/or high temperature. Note: At the maximum usage temperature of 250 °C and the maximum operating pressure, the temperature difference in the glass wall of the flat flange reaction vessels must not exceed 30 °C.
