Description
Receiving flask according to Schlenk, cylindrical 500 ml with NS 29/32 ground joint is laboratory glassware intended for the collection of distillates and reaction products under inert or vacuum conditions. It features a round-bottom cylindrical body equipped with a lateral stopcock that carries a hollow plug and glass handle. The stopcock bore measures 2,5 mm and the side arm terminates in an NS 14,5 joint fitted with an 8 mm olive for flexible tubing. Overall dimensions are 250 x 70 mm. Delivered as one piece, the flask is well suited to Schlenk techniques commonly employed in air- and moisture-sensitive synthetic chemistry. The design permits secure isolation of collected fractions while allowing controlled gas exchange or evacuation. Offered by manufacturer Witeg, the vessel connects directly to standard ground-joint distillation and vacuum-transfer setups. Ideal for organic synthesis, organometallic work and preparative distillation, this 500 ml receiving flask supplies a robust solution for laboratories needing reliable inert-atmosphere liquid handling at intermediate scale.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 500 ml ST 29
What is this article?
Collecting flask cylindrical 500 ml ST 29 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.
