Description
GUKO rubber seal set 21-86 mm comprises seven conical rubber gaskets covering the nominal size range 21-86 mm measured as outer diameter at the top. These conical seals are designed for sealing Büchner funnels, filter nutsches and related laboratory filtration equipment, ensuring a reliable fit between glassware components during vacuum or gravity filtration. The complete set is supplied as one unit with a net weight of 0,164 kg, providing a practical assortment for laboratories that handle multiple funnel diameters. Manufactured by Witeg, the GUKO seals support leak-free connections in sample preparation, solid-liquid separation and general wet-chemistry workflows. Their conical geometry accommodates common laboratory glassware interfaces and helps maintain vacuum integrity. Originating from South Korea, the set is a convenient consumable for research, quality-control and teaching environments that require interchangeable rubber seals across a broad size spectrum. Ideal for nutsche filtration and related applications, the assortment reduces the need to source individual gaskets separately while covering everyday laboratory sealing needs.

Questions about Guko-Set rubber gaskets 21-86 mm
What is this article?
Guko-Set rubber gaskets 21-86 mm is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Cutting & sealing tools, inside Tools & accessories, in Matériel de laboratoire.
Cutting and sealing tools score glass tubing, trim a stopper, or close a bag and a film. A glass cut that is only scored, not pulled, shatters instead of breaking clean.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
