capillary tubes and bars BORAN® Mennes GmbH

temperature-change resistant ~ pressure resistant

Tubes, capillary tubes and bars made of Borosilicate glass BORAN® made by MENNES GmbH are known for their stability and their resistance against quick temperature changes. They are used in industrial plant construction, in the laboratory industry or the lighting industry.

We can offer drillings, millings, cut-outs and special processing on high-performance machines. Tube tapering and tube flaring is also possible on request. Sealing of two or more tube sections is realizable.
The maximum length, that has ever been produced by us, amounts to 8600 mm.
