Description
Guko set of conical EPDM rubber seals for suction flasks is an eight-piece assortment covering sizes 22 to 84, designed to create a reliable gas-tight connection between a filter funnel and a suction flask. The conical rubber sleeves protect the glassware from breakage while ensuring the airtight seal required for vacuum filtration. Made from durable EPDM rubber, the seals accommodate common laboratory filter and flask combinations used in routine solid–liquid separations. Their tapered geometry allows quick seating and a secure fit under reduced pressure, supporting clean, efficient filtration workflows in analytical, preparative and teaching laboratories. Supplied as a complete set from manufacturer Duran/DWK Life Sciences, the assortment provides the most frequently needed diameters in one package, reducing the need to stock individual sizes. Ideal for sealing and filtration applications where a dependable vacuum-tight joint between glass components is essential, these conical Guko seals offer a practical, reusable solution for everyday vacuum filtration setups.

Questions about Rubber Conical Gasket Guko Set, 8 pieces, made from EPDM, for filtering flasks
What is this article?
Rubber Conical Gasket Guko Set, 8 pieces, 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.
