The standard Atlas Jacketed Vessel lid fits all Atlas Jacketed Vessels and locates within the Jacketed Vessel Clamp (2101012) to make a repeatable seal quick and easy. The lid has a B24 Centre port (for the Stirrer Seal and Guide - 2101011) , 2xB19 straight, 2xB29 angled ports for connection of other glassware (temperature probes, condensers, addition funnels etc).

The Jacketed Vessel Lid seals against the top of the Jacketed Vessel using a Reaction Vessel Seal in FEP (2101016) or FFKM (2101543). US lids have longer cones.
