Description
Three-neck round-bottom flask with parallel necks and standard ground joints is a multi-neck laboratory flask made from borosilicate glass 3.3 (LBG 3.3). It offers a nominal volume of 0,25 l with centre joint NS 29/32, enabling condensers, dropping funnels, stirrer guides or temperature probes to be connected at three parallel ports. The round-bottom form suits heating and stirring in smaller-scale synthesis, distillation and collection setups, while parallel necks keep fittings aligned for compact glassware trains. This flask from manufacturer Labbox is manufactured in borosilicate glass LBG 3.3 and belongs to the LBG product type for round-bottom, ground-joint, distillation and receiver use. Net weight is 0,128 kg. Supplied as 1 pc, it matches standard clamps and heating accessories for 0,25 l round-bottom flasks. Three NS 29/32 necks provide simultaneous access to the vessel for multi-component assemblies in teaching and research laboratories that need parallel centre and side connections on a quarter-litre scale.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, round bottom with three necks (parallel), LBG 3.3, cent. 29/32, side 14/2
What is this article?
Flask, round bottom with three necks (parallel), LBG 3.3, cent. 29/32, side 14/2 is the article on this page. Luminix Health distributes Labbox 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.
