Description
Four-neck round-bottom flask with angled necks and standard ground joints in borosilicate glass 3.3 is built for larger multi-port reaction, distillation and process work. With a nominal volume of 1 l and a principal joint size of NS 29/32, the vessel accommodates condensers, stirrer guides, dropping funnels, thermometers and gas inlets in a single compact assembly. Constructed from borosilicate glass 3.3 from manufacturer Labbox, it offers the thermal-shock resistance and chemical durability expected of LBG laboratory glassware, while the round bottom promotes uniform heating in mantles or baths. Approximate net weight is 0,466 kg. The four-neck layout with angled side arms improves instrument clearance and reduces congestion above the centre neck, which is especially useful in 1000 ml-scale synthesis, fractionation and receiver setups. Suitable for use as a round-bottom flask, ground-joint flask, distillation flask or collecting flask. Supplied as one piece for straightforward integration into existing NS ground-joint systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, Round Bottom, 4 Necks Angular, 1000 ml, 29/32 and 19/26
What is this article?
Flask, Round Bottom, 4 Necks Angular, 1000 ml, 29/32 and 19/26 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.
