Description
Ground three-neck round-bottom flask with inclined necks, LBG 3.3, centre NS 19/26, long is a small multi-neck round-bottom flask intended for laboratory synthesis, distillation and collection tasks. Fabricated from borosilicate glass LBG 3.3, it provides three ground necks on a round-bottom body so several accessories can be connected at once. The centre neck is finished to NS 19/26, and the side necks are inclined to improve clearance when condensers, addition funnels or sensors are fitted alongside the main port. Nominal volume is 0,1 l, making the vessel practical for limited-scale work where a compact three-neck layout is preferred. The long neck form helps with secure holding and keeps joints accessible during heating or reflux operations. Net weight is 0,070 kg. Supplied as 1 pc from manufacturer Labbox within the LBG range, the flask corresponds to typical laboratory use as a round-bottom flask, ground-joint flask, distillation flask or receiving flask. The NS 19/26 centre joint is compatible with matching standard ground-joint glassware in multi-neck setups.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, round bottom with three necks (side angle), LBG 3.3, cent. 19/26, lat. 14
What is this article?
Flask, round bottom with three necks (side angle), LBG 3.3, cent. 19/26, lat. 14 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.
