Description
Flat-bottom flasks DURAN® with narrow neck and 250 ml capacity provide stable laboratory glass vessels for everyday chemical and preparative work on the bench. The flat base stands securely without a cork ring or clamp, supporting solution preparation, temporary storage of liquids, and handling steps where a free-standing flask is more convenient than a round-bottom design. This pack of 10 pieces from manufacturer DWK Life Sciences has a total weight of 1,300 kg and is practical for laboratories that need a ready supply of mid-volume glassware. Narrow-neck construction aids controlled pouring and helps limit evaporation and splash during use, while remaining suitable for common laboratory closures. Positioned within the standard category of round flasks and laboratory glass vessels, these 250 ml flasks fit teaching, research, and quality-control workflows involving media, reagents, and sample aliquots. The multipack format supports efficient restocking of frequently used flat-bottom flasks so that DURAN® vessels in this capacity remain available for routine experimental and preparatory tasks across the laboratory.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Flat-bottom flasks, DURAN®, narrow neck, 250 ml, 10 unit(s)
What is this article?
Flat-bottom flasks, DURAN®, narrow neck, 250 ml, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
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.
