Description
Filter flask borosilicate glass 3.3, 500 ml is a laboratory filtration and vacuum flask with a nominal volume of 0,5 l. Fabricated from borosilicate glass 3.3, it is intended for filtration duties, vacuum bottle use and laboratory workflows that need a robust receiver under reduced pressure. The 500 ml capacity supports larger single filtrations or higher sample volumes in research, production support and routine analytical laboratories. This filter flask from manufacturer Hecht belongs to the established glassware group of filtration bottles, Woulff-type bottles and vacuum flasks. It is supplied as 1 pc for simple stocking of benches, fume hoods and dedicated filtration stations. Product data specify borosilicate glass 3.3 as the material and 0,5 l as the nominal volume, giving a clear match to standard vacuum filtration assemblies. Select the 500 ml format when a larger borosilicate filter flask is required for everyday laboratory vacuum filtration and related reduced-pressure collection tasks.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Filtering flasks of borosilicate glass 3.3 500 ml
What is this article?
Filtering flasks of borosilicate glass 3.3 500 ml is the article on this page. Luminix Health distributes Hecht 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.
