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.
