Description
DURAN® three-neck round-bottom flask with standard ground joints (NS) offers a centre neck NS 24/29 and two parallel vertical side necks NS 19/26 at a nominal volume of 500 ml. Made from borosilicate glass 3.3, this multi-neck flask serves distillation, fractionation and reaction applications in which condensers, columns, thermometers, dropping funnels or boiling capillaries can be installed as needed. Vertical side necks combined with the flask geometry allow very uniform heating in heating baths or heating mantles. Precision standard ground joints provide a tight seal, and the white printed marking is fired into the glass for permanent durability. The flask from manufacturer Duran/DWK Life Sciences is also appropriate for extraction, connection to other glassware and general heating operations. It is supplied as one piece. Multi-neck round-bottom flasks of this type are standard equipment in preparative and synthetic laboratories requiring flexible accessory attachment. The 500 ml size with the NS 24/29 centre-joint arrangement is not manufactured according to DIN ISO. Net weight is 0,202 kg.
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.
