Description
Round-bottom flask 1000 ml with three necks is a multi-neck reaction vessel for laboratory synthesis, distillation and multi-port experimental setups. The centre neck carries a standard ground joint NS 24/29, while two side necks angled at 20° feature NS 19/26 joints, allowing simultaneous connection of condensers, dropping funnels, thermometers or gas inlets. Manufactured from clear borosilicate glass 3.3, the flask offers high chemical resistance and thermal stability suited to heating and cooling cycles common in organic and inorganic chemistry. With a nominal volume of 1 l, this three-neck design from manufacturer Witeg supports reflux, distillation and reaction-monitoring applications. The round-bottom geometry promotes even heat distribution when used with heating mantles or oil baths. Supplied as a single piece, the flask is intended for research, teaching and quality-control laboratories that require versatile multi-neck glassware with standardised European ground joints for flexible apparatus assembly and reliable performance under routine laboratory conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 1000 ml three necks CN ST 24/29
What is this article?
Round bottom flask 1000 ml three necks CN ST 24/29 is the article on this page. Luminix Health distributes Witeg 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.
