Beschrijving
Guko conical rubber seal made of EPDM, featuring a lower diameter of 16 mm and an upper diameter of 29 mm, connects a filter funnel to a suction flask for vacuum filtration. The tapered rubber sleeve protects the glassware from breakage while establishing the gas-tight seal essential for maintaining vacuum throughout the filtration process. Produced from durable EPDM, the seal provides a secure, reusable fit under reduced pressure and supports efficient solid–liquid separations in everyday laboratory practice. Its conical geometry matches common suction-flask and filter combinations of this size range, serving as a convenient single-size component or replacement. Available as an individual piece from manufacturer Duran/DWK Life Sciences, the seal is intended for sealing and filtration applications where a reliable airtight joint between glass parts is required. Well suited to analytical, preparative and teaching laboratories that perform routine vacuum filtration.
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 Labmateriaal.
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.
