Description
Filter flask 250 ml 155 x 85 mm is an Erlenmeyer-form filtration flask equipped with a lateral olive, designed for vacuum filtration and related laboratory procedures. Manufactured from borosilicate glass 3.3 and protected by a WITOSINT safety coating, it provides high chemical durability together with improved resistance to mechanical stress. The flask measures 155 x 85 mm and holds a nominal volume of 250 ml (0,25 l), making it suitable for medium-scale sample filtration, clarification and vacuum-assisted transfers in organic synthesis, analytical chemistry and quality-control workflows. The side olive allows convenient and secure attachment of vacuum tubing. This filter flask from manufacturer Witeg unites the proven performance of borosilicate glass with an additional safety layer for everyday laboratory use. Its Erlenmeyer geometry offers a stable base on the workbench, while the coating reduces the impact of accidental contact. The unit is well suited to research, educational and industrial environments requiring dependable vacuum flasks of intermediate capacity.

Questions about Filter flasks Erlenmeyer shape
What is this article?
Filter flasks Erlenmeyer shape 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.
