The Atlas Vessel Lids fit all Atlas Jacketed Vessels and locate within the Jacketed Vessel Clamp (2101012). They seal against the top of the Jacketed Vessels using a Reaction Vessel Seal in FEP (2101016) or FFKM (2101543). They have 7 ports in total:

• 1 x vertical A24 centre port for the Stirrer Seal and Guide
• 3 x A19 ports designed for probes, sensors and condensers and are set at an angle of 15° with a compound angle of 5° to avoid clashing with items in other ports or the stirrer
• 1 x A29 port for larger probes, condensers or manual additions
• 2 x vertical GL18 ports designed to accept Atlas Jacketed Reactor Baffles or other devices with suitable adaptors

The US version has longer cones to fit longer US ground glass joints.
