Beschrijving
Schlenk flask, 500 ml, with socket NS 29/32 is a robust laboratory vessel engineered for handling air- and moisture-sensitive reagents under inert atmosphere or vacuum. Made from borosilicate glass 3.3, it features a lateral high-vacuum PTFE valve with fine thread for precise control of gas exchange. The valve provides a passage range of 0–8 mm together with an olive of Ø 9 mm, allowing reliable connection to vacuum or inert-gas systems. Ideal for standard Schlenk operations such as degassing, cannula transfer and reaction isolation, the design maintains an oxygen-free environment throughout multi-step procedures. Available from manufacturer Rettberg, the flask offers a nominal volume of 500 ml and a net weight of 0,218 kg, suiting intermediate-scale synthetic chemistry, organometallic work and catalyst studies. The NS 29/32 ground joint guarantees compatibility with common laboratory glassware including condensers and addition funnels. Delivered as 1 pc, this Schlenk apparatus forms a dependable element of vacuum manifolds and inert-gas lines in research and development laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 500 ml, socket size 29/32, PTFE high vacuum-valve
What is this article?
Nitrogen flask, 500 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 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.
