Reaction Vessel Lid with 3 Ground Glass Joints – Borosilicate Glass 3.3

Reaction vessel lids made of high-quality borosilicate glass 3.3 with three precisely manufactured ground glass joints for professional laboratory use. The lids feature a central middle neck and two laterally positioned ground glass joints arranged at an angle of approx. 15° to the center neck. This construction allows simultaneous connection of multiple laboratory components such as stirring shafts, thermometers, dropping funnels, inlet and outlet lines, or sampling devices with optimal accessibility.

The lids are available in various nominal diameters (DN 60 to DN 200) and with different standard ground joint combinations, suitable for a wide range of reaction vessels and laboratory setups. The use of borosilicate glass 3.3 ensures chemical resistance, thermal stability, and suitability for demanding synthesis work, distillations, and reaction control.
