Description
Erlenmeyer flasks DURAN®, 50 ml, are conical laboratory flasks in DURAN® borosilicate glass fitted with a standard ground joint NS 19/26. Manufactured to DIN 12387, they measure 51 mm in diameter and 85 mm in height, providing a balanced size for intermediate-scale mixing, heating and short-term storage of solutions. The wide base improves stability on the bench and under magnetic stirring, while the tapered neck limits evaporation and splash during swirling. The ground joint supports secure connection to condensers, drying tubes or stoppers in jointed glass assemblies. Supplied as a pack of 10 pieces, these flasks from manufacturer Lenz are well suited to synthetic chemistry, analytical sample work-up, culture media handling and educational laboratories. DURAN® glass offers the thermal shock resistance and chemical inertness required for routine laboratory operations. Clearly specified dimensions aid selection of compatible heating blocks, clamps and storage racks. The 50 ml nominal volume bridges small and medium working scales without excess headspace or reagent consumption.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Erlenmeyer flasks, DURAN®, 50 ml, joint 19/26, DIN 12387, Ø 51 mm, H 85 mm
What is this article?
Erlenmeyer flasks, DURAN®, 50 ml, joint 19/26, DIN 12387, Ø 51 mm, H 85 mm 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.
