Description
Four-neck round-bottom flask with angled necks and standard ground joints is a multi-port laboratory vessel for reaction, distillation and synthesis work. Made from borosilicate glass 3.3, it combines chemical resistance with good thermal stability for everyday laboratory use. The flask has a nominal volume of 500 ml (0,5 l) and four necks fitted with standard ground joints in sizes NS 29/32 and NS 14/23, so condensers, dropping funnels, stirrers, thermometers or gas inlets can be connected at the same time. The angled neck layout improves access around the vessel and supports practical reflux, addition and sampling arrangements. Net weight is 0,173 kg. This robust ground-joint flask from manufacturer Labbox fits common laboratory glassware systems used in organic chemistry, preparative work, teaching laboratories and pilot-scale setups. It is supplied as one piece and is suitable wherever round-bottom, ground-joint, distillation or receiver flasks are required for multi-component reactions and controlled heating or cooling under standard laboratory conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, Round Bottom, 4 Necks Angular, 500 ml, 29/32 and 14/23
What is this article?
Flask, Round Bottom, 4 Necks Angular, 500 ml, 29/32 and 14/23 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.
