Description
Vacuum manifold with 5 valves is a laboratory vacuum distribution comb for controlled high-vacuum work. It is fitted with five PTFE high-vacuum valves offering an adjustable passage from 0 to 6 mm, so individual lines can be opened, throttled or closed with precision. Hose connections use 8 mm olives for secure attachment of flexible tubing. The body is made of borosilicate glass 3.3, giving the chemical resistance and thermal stability expected of quality laboratory glassware. This vacuum manifold from manufacturer Witeg supports multi-port vacuum distribution in distillation, filtration, Schlenk-line and inert-atmosphere setups. PTFE valve components provide reliable sealing across the full adjustment range, while the glass construction withstands common laboratory solvents and temperature changes. Supplied as one piece with a net weight of 0,43 kg, the compact unit integrates easily into existing bench or fume-hood vacuum systems. The five-valve layout simplifies parallel experiments and reduces the need for separate stopcocks, making it a practical accessory for research and analytical laboratories that require flexible, fine-controlled vacuum distribution.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Vacuum Manifolds, vacuum distribution tu
What is this article?
Vacuum Manifolds, vacuum distribution tu 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.
Which category should I open next?
