Description
Schlenk flask, 2000 ml, with socket NS 29/32 is a large-capacity laboratory vessel intended for air- and moisture-sensitive chemistry performed under inert atmosphere or vacuum. Constructed from borosilicate glass 3.3, it is equipped with a lateral high-vacuum PTFE valve featuring a fine thread for accurate regulation of gas flow. The valve delivers a passage of 0–10 mm and an olive of Ø 9 mm, ensuring secure attachment to vacuum lines or inert-gas manifolds. This design supports extended Schlenk techniques including bulk degassing, solvent manipulation and larger-scale reaction work-up while excluding oxygen and water. Offered by manufacturer Rettberg, the flask provides a nominal volume of 2000 ml and a net weight of 0,495 kg, making it appropriate for preparative synthetic chemistry, organometallic synthesis and materials research. The standardized NS 29/32 ground joint maintains full compatibility with condensers, dropping funnels and other jointed apparatus. Supplied as 1 pc, the unit integrates smoothly into existing Schlenk lines and vacuum systems used in academic and industrial laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 2000 ml, socket size 29/32, PTFE high vacuum-valve
What is this article?
Nitrogen flask, 2000 ml, socket size 29/32, PTFE high vacuum-valve 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.
