Description
Filter flask 250 ml 155 x 85 mm is an Erlenmeyer-form filtration flask fitted with a lateral olive for vacuum tubing connection. Manufactured from DURAN tubing and supplied uncoated, it is produced in borosilicate glass 3.3, delivering the chemical resistance and thermal stability required for laboratory vacuum filtration. The nominal volume is 0,25 l with overall dimensions of 155 x 85 mm and a net weight of 0,13 kg. This filter flask from manufacturer Witeg is intended for routine vacuum filtration of solutions and suspensions in analytical chemistry, sample preparation and general laboratory workflows. The side olive provides a secure attachment point for vacuum lines when used with Büchner funnels or similar assemblies. Offered in packs of 10 pieces, the uncoated construction preserves optical clarity and surface inertness. Suitable for research, quality-control and educational laboratories, the flask supports reliable filtration performance under typical laboratory vacuum conditions while remaining easy to clean and handle.

Questions about Filter flasks 250 ml
What is this article?
Filter flasks 250 ml is the article on this page. Luminix Health distributes Witeg 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.
