Description
PTFE vacuum seal is a compact sealing element intended for stirrer heads used in laboratory vacuum work. Fabricated entirely from PTFE, the component forms a chemically resistant barrier that helps maintain reduced-pressure conditions when fitted to compatible stirring assemblies. Its low mass of 0,001 kg ensures negligible influence on the balance or dynamics of the apparatus. Supplied as a single piece, the seal functions as a practical spare or replacement part for routine maintenance of vacuum stirring setups. The PTFE construction offers broad compatibility with common organic solvents and reagents encountered in synthesis, extraction and process-development laboratories. Mid-description reference notes that the item originates from manufacturer Witeg and belongs to the stirrer-closure category. Laboratories performing overhead or rotary stirring under vacuum will find this seal useful for restoring or preserving joint integrity on glassware systems. The simple geometry allows straightforward installation without specialised tools, supporting efficient workflow continuity in research and analytical environments where reliable vacuum sealing is essential.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about PTFE-vacuum seal for stirrer guides
What is this article?
PTFE-vacuum seal for stirrer guides is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
