Description
Guko EPDM conical rubber seals for suction flasks enable a secure, gas-tight connection between a filter and a suction flask during vacuum filtration. Made from EPDM rubber in a conical shape, the seal protects both glass components from breakage while maintaining the airtight joint required for effective vacuum work. This version features a lower diameter of 43 mm and an upper diameter of 63 mm, matching common laboratory filtration assemblies. A permanently baked-in white print ensures lasting identification. Supplied as a single piece, the Guko seal from manufacturer Duran/DWK Life Sciences is intended for sealing and filtration applications in research and analytical laboratories. The flexible conical geometry allows straightforward fitting and removal yet holds vacuum integrity throughout the process. EPDM construction provides the resilience needed for repeated laboratory use. Net weight is 0,03 kg. These conical rubber gaskets support reliable vacuum filtration workflows wherever a durable, gas-tight interface between filter funnel and suction bottle is essential.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Rubber Conical Gasket Guko, made from EPDM, for filtering flasks
What is this article?
Rubber Conical Gasket Guko, made from EPDM, for filtering flasks is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
