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 provides a nominal volume of 1 l with centre joint NS 29/32, so condensers, dropping funnels, stirrer guides or temperature probes can be fitted at three parallel ports. The round-bottom geometry supports heating and stirring during synthesis, distillation and collection work, while the parallel neck layout keeps ground-joint accessories aligned on one plane for compact apparatus trains. Produced in borosilicate glass LBG 3.3 by manufacturer Labbox, the flask is part of the LBG product type used for round-bottom, ground-joint, distillation and receiver applications. Net weight is 0,353 kg. Supplied as 1 pc, it integrates with standard laboratory clamps and heating equipment sized for one-litre round-bottom flasks. Three NS 29/32 necks give simultaneous access to the vessel interior for multi-component glassware assemblies in teaching and research laboratories that require parallel side and centre connections.
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 19/2
What is this article?
Flask, round bottom with three necks (parallel), LBG 3.3, cent. 29/32, side 19/2 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.
