Description
Claisen distillation bridge 400 mm is a laboratory glassware component configured for distillation according to the Claisen design. It combines a Liebig condenser (west type) with a 400 mm jacket length, two NS 14/23 sockets, and NS 29/32 joints for the flask and receiver, enabling efficient vapour transfer and condensation in standard ground-joint assemblies. The bridge supports fractional and vacuum distillation workflows commonly used in organic synthesis, purification and analytical laboratories. Supplied as a single piece from manufacturer Witeg, it integrates readily into existing distillation trains that rely on NS joint systems. The Claisen-style side arm allows convenient connection of secondary apparatus or addition funnels while the Liebig cooling section provides reliable heat exchange along the 400 mm mantle. With a net weight of 0,4 kg, the unit is practical for routine bench and fume-hood setups. Ideal for research and teaching environments requiring defined joint sizes and a clearly specified condenser jacket length for reproducible distillation performance.

Questions about Distilling links, Claisen, Liebig cond.
What is this article?
Distilling links, Claisen, Liebig cond. is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
