Description
Schlenk flask, 50 ml, with socket NS 29/32 is a compact laboratory vessel designed for inert-atmosphere and vacuum techniques. Fabricated from borosilicate glass 3.3, it features one neck with an NS 29/32 ground joint and a lateral glass stopcock equipped with a solid glass plug. The stopcock has a 2,5 mm bore and a 9 mm olive for secure connection to tubing. The 50 ml nominal volume is well suited to small-scale reactions, sample storage and transfer of air-sensitive compounds. This Schlenk apparatus from manufacturer Rettberg connects directly to standard Schlenk lines and vacuum manifolds through the NS 29/32 socket. Borosilicate glass 3.3 supplies the chemical and thermal durability required in everyday synthetic work. Net weight is 0,089 kg, keeping the flask easy to manipulate on the bench. The side-arm stopcock permits controlled evacuation and inert-gas back-fill, supporting organometallic chemistry, moisture-sensitive procedures and teaching experiments that demand reliable exclusion of air and moisture.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 50 ml, socket size 29/32, side stopcock 2,5 mm bore,
What is this article?
Nitrogen flask, 50 ml, socket size 29/32, side stopcock 2,5 mm bore, is the article on this page. Luminix Health distributes Rettberg 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.
