Description
Round-bottom flask 1000 ml three necks with centre neck NS 29/32 and two angled side necks NS 19/26 is a clear laboratory vessel designed for larger-scale multi-port reactions, distillations and synthesis. Produced from borosilicate glass 3.3, it offers reliable chemical resistance and thermal stability under typical laboratory heating and cooling cycles. The vertical centre neck features a standard ground joint NS 29/32, while the two side necks are set at 20° with NS 19/26 joints, providing convenient ports for condensers, dropping funnels, stirrers or temperature sensors. Nominal volume is 1000 ml (1 l). This flask from manufacturer Witeg suits preparative organic chemistry, reflux, fractionation and receiving duties where simultaneous multi-neck access is essential. The round-bottom geometry ensures even heat transfer and efficient mixing when used with heating mantles or oil baths. Clear glass walls allow unobstructed visual monitoring of the reaction. Supplied as a single piece, it supports research, scale-up and teaching laboratories that require robust multi-neck glassware for distillation and synthetic workflows.
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 29/32
What is this article?
Round bottom flask 1000 ml three necks CN ST 29/32 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.
