Receiving flask according to Schlenk 500 ml cylindrical NS 29/32 is a laboratory glass vessel engineered for distillate collection in Schlenk and vacuum distillation setups. Its cylindrical form with round bottom incorporates a ground joint sleeve NS 29/32 that mates directly with standard apparatus. The lateral stopcock features a hollow plug, glass handle and 2,5 mm bore for precise flow control, complemented by a side arm with NS 14,5 joint and 8 mm olive for flexible tubing connection. Dimensions measure 250 × 70 mm. Delivered as one piece with a net weight of 0,32 kg, the flask provides ample capacity for preparative work while remaining compatible with common ground-joint systems. Produced by manufacturer Witeg, this receiving flask is well suited to organic synthesis, solvent recovery and the handling of air- or moisture-sensitive compounds. The configuration allows secure integration into distillation trains and inert-atmosphere manifolds used throughout research and analytical laboratories, ensuring reliable containment and transfer of collected fractions.

Questions about Collecting flask cylindrical 500 ml ST29
What is this article?
Collecting flask cylindrical 500 ml ST29 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labmateriaal.
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.
