Description
DURAN® three-neck round-bottom flask with standard ground joints (NS) and vertical side necks is a multi-neck laboratory flask offering a nominal volume of 2000 ml (2 l). It is fitted with a centre neck NS 29/32 and parallel side necks also NS 29/32. Multi-neck flasks of this type are mainly used for distillation, fractionation and reaction work, allowing attachments, columns, thermometers, dropping funnels, boiling capillaries and similar components to be mounted as needed. The standard ground joints deliver a tight seal, and the vertical side-neck arrangement combined with the flask geometry enables very uniform heating. Made from borosilicate glass 3.3 by Duran/DWK Life Sciences, the flask bears a fired-on white print that remains permanently durable. Typical uses include distillation, extraction, connection to further glass apparatus, heating, and employment in heating baths and heating mantles. The 2000 ml size with NS 29/32 is not manufactured according to DIN ISO. Supplied as a single piece, this three-neck round-bottom flask supports flexible multi-port configurations for laboratory procedures that require concurrent connection of several accessories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about DURAN® Triple-Neck Round Bottom Flask,standard ground joint, parallel side necks
What is this article?
DURAN® Triple-Neck Round Bottom Flask,standard ground joint, parallel side necks is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
