Description
Three-neck round-bottom flask with parallel necks and standard ground joints is a multi-neck laboratory flask fabricated from borosilicate glass LBG 3.3. It is intended for reaction, distillation and collection applications that need simultaneous access through several ports. The centre neck carries an NS 29/32 standard ground joint, with two additional necks arranged parallel to the centre neck. Nominal volume is 0,5 l.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
Made from borosilicate glass 3.3 (Labbox) as part of the LBG product type, the flask integrates with common ground-joint laboratory assemblies. Parallel necks simplify connection of condensers, addition funnels, mechanical stirrers or probes in a tidy footprint. Net weight is 0,185 kg. Delivered as 1 piece, it serves organic chemistry, preparative work and instructional labs that use round-bottom flasks, ground-joint flasks, distillation flasks and receiver flasks. Joint size and material choice match routine multi-neck glassware requirements.

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.
