Description
4-Neck flask 500 ml with straight side necks is a compact multi-neck round-bottom laboratory flask for synthesis, distillation and multi-port reaction set-ups at medium scale. It features a centre neck and straight side necks, all finished with NS 29/32 ground joints, enabling reliable connection of condensers, stirrers, dropping funnels and monitoring probes. The nominal volume of 0,5 l is practical for routine preparative work while the four-neck configuration supports simultaneous addition, reflux and observation without frequent apparatus changes. From manufacturer Witeg, this flask is appropriate for organic synthesis, fractional distillation and multi-component reactions in research and teaching laboratories. Straight side-neck geometry helps avoid angular clashes when several glassware items are assembled together, improving stability on the bench or in a heating mantle. With a net weight of 0,276 kg the vessel is easy to handle yet suitable for repeated thermal use. Typical roles include reaction flask, distillation receiver and general multi-neck vessel wherever standardised NS 29/32 joints and versatile access ports are required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, 4 necks, necks parallel, 500 m
What is this article?
Flasks, 4 necks, necks parallel, 500 m is the article on this page. Luminix Health distributes Witeg 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.
