Description
Suction flask, 5 l, stopper and tube is a vacuum-resistant borosilicate glass bottle designed for collecting larger volumes of filtrate under reduced pressure. The 5 l nominal capacity, combined with the supplied stopper and tube, supports efficient connection to filtration assemblies and vacuum lines commonly used in laboratory workflows. Made from borosilicate glass 3.3, the flask offers the chemical resistance and mechanical stability required for repeated vacuum filtration duties. With a net weight of 3,186 kg and delivered as one complete unit, it is well suited to preparative or higher-throughput filtration tasks in chemistry, microbiology and process laboratories. This suction flask from Sartorius provides a clear, durable collection vessel that allows visual inspection of the filtrate while maintaining vacuum integrity. The included stopper and tubing components simplify setup, helping laboratories establish reliable filtrate recovery for analytical, research and quality-control applications that demand a larger working volume.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Suction flask, 5 l, stopper and tube
What is this article?
Suction flask, 5 l, stopper and tube is the article on this page. Luminix Health distributes Sartorius 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.
