Description
Erlenmeyer flasks, DURAN®, 250 ml are conical laboratory vessels fitted with a ground joint 29/32 and manufactured to DIN 12387. With a diameter of 85 mm and a height of 139 mm, they offer a convenient working volume for mixing, heating, buffer preparation and intermediate sample handling. The DURAN® glass construction delivers the optical clarity and mechanical stability needed for daily chemical and biological laboratory use. Each pack comprises 10 pc(s) and weighs 1,310 kg, making the format practical for restocking shared instrument rooms and teaching facilities. Produced by manufacturer Lenz, the flasks accept standard NS 29/32 stoppers and adapters and therefore slot easily into established ground-joint setups. The broad base and narrow neck support efficient swirling while reducing splash risk during titration, crystallization or culture procedures. Compliance with DIN 12387 dimensions aids interchangeability across multi-user benches. From routine reagent work to analytical sample preparation, the 250 ml DURAN® Erlenmeyer flask remains a versatile choice for laboratories that depend on consistent conical glassware.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, DURAN®, 250 ml, joint 29/32, DIN 12387, Ø 85 mm, H 139mm
What is this article?
Erlenmeyer flasks, DURAN®, 250 ml, joint 29/32, DIN 12387, Ø 85 mm, H 139mm is the article on this page. Luminix Health distributes Lenz 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.
