Description
Schlenk flask, 100 ml, with socket NS 29/32 is a laboratory vessel for handling substances under vacuum or inert gas. Constructed from borosilicate glass 3.3, it offers a single neck with NS 29/32 ground joint together with a lateral glass stopcock that incorporates a solid glass plug. The stopcock delivers a 2,5 mm bore and terminates in a 9 mm olive for tubing attachment. The 100 ml nominal volume provides a practical working capacity for medium-scale synthesis, intermediate storage and solvent transfer under controlled atmosphere. This Schlenk apparatus from manufacturer Rettberg fits standard Schlenk manifolds and vacuum systems via the NS 29/32 socket. Borosilicate glass 3.3 ensures good resistance to thermal shock and common laboratory chemicals. Net weight is 0,105 kg, balancing robustness with convenient handling. The side-arm stopcock arrangement allows stepwise evacuation and inert-gas refill, making the flask suitable for organometallic work, air-sensitive preparations and instructional laboratories that rely on reliable Schlenk technique.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 100 ml, socket size 29/32, side stopcock 2,5 mm bore,
What is this article?
Nitrogen flask, 100 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.
