Reaction Vessel Lid with 5 Ground Joints – DN 100–200 – Borosilicate glass 3.3

High-quality reaction vessel lids with ground flange for professional laboratory syntheses and chemical reactions. The lids are manufactured from borosilicate glass 3.3 and offer maximum chemical and thermal resistance for demanding laboratory applications.

Product Features:

The reaction vessel lids feature a central center neck with ground joint NS 29/32 or NS 45/40 as well as three side necks NS 29/32 arranged at an angle of approx. 15° to the center neck. Additionally, one straight side neck NS 14.5/23 is integrated. This configuration enables the simultaneous connection of multiple components such as stirrers, thermometers, dropping funnels, or reflux condensers.

The flange DN (nominal diameter) is available in various sizes from 100 mm to 200 mm and enables secure mounting on corresponding reaction vessels. The ground seating surface ensures a tight connection to the vessel body.

Applications:

• Chemical syntheses under controlled conditions
• Reaction control with multiple additives
• Distillations and reflux reactions
• Inert gas work and protective gas applications
• Pharmaceutical and organic synthesis processes
