Description
DURAN® flat-bottom flask with NS 29/32 is a 50 ml laboratory vessel made of borosilicate glass 3.3. Flat-bottom flasks are a form variant of round-bottom flasks and feature a flattened base on which they can stand freely. The standard ground joint provides a precise, tight connection to further ground-glass components such as columns, thermometers, dropping funnels and ground stoppers. Because of their geometry, flat-bottom flasks are intended only for work without pressure. Special advantages include a dense seal via the standard joint, a permanently fired-on white print for durable marking, and the ability to set the flask down without a support ring thanks to the flat base. Typical laboratory uses include dilution of solutions and heating. This DURAN® flask from manufacturer Duran/DWK Life Sciences is supplied in packs of 10 pieces. Certain larger volume and joint combinations in the series are not manufactured according to DIN ISO, while this compact 50 ml NS 29/32 format serves routine bench work where a free-standing vessel with a reliable ground joint is required.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about DURAN® Flat Bottom Flask, with standard ground joint
What is this article?
DURAN® Flat Bottom Flask, with standard ground joint 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.
