Description
Vacuum manifold with 4 valves enables multi-port vacuum distribution for laboratory glassware and process setups. It is equipped with four PTFE high-vacuum valves offering an adjustable passage from 0 to 6 mm, so each line can be isolated or opened with precise control. Connections are made via 8 mm hose olives, and the overall length of the manifold is 340 mm. Fabricated from borosilicate glass 3.3, the unit combines mechanical robustness with excellent chemical resistance under reduced pressure. This vacuum distribution comb from manufacturer Witeg is intended for Schlenk lines, freeze-drying accessories and multi-station vacuum workstations where dependable sealing is required. The PTFE valve components support high-vacuum performance while remaining straightforward to operate day to day. Net weight is 0,332 kg. Supplied as a single piece, the manifold streamlines vacuum routing in organic synthesis, materials processing and analytical sample handling, helping laboratories maintain clean, organised reduced-pressure networks across several concurrent experiments.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Vacuum manifold with 4 valves
What is this article?
Vacuum manifold with 4 valves is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labware.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
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.
