Description
Schlenk flask, 100 ml, socket NS 29/32 is a specialized single-neck laboratory flask engineered for air- and moisture-sensitive chemistry. Constructed from durable borosilicate glass 3.3, it incorporates a lateral PTFE valve adjustable from 0 to 3 mm together with an 8 mm olive for connection to vacuum or inert gas lines. The NS 29/32 ground joint socket provides secure mating with standard glassware. With a nominal volume of 100 ml, this Schlenk apparatus suits medium-scale reactions, solvent transfers and storage of reactive intermediates under controlled atmosphere. The side valve enables precise regulation of gas flow or vacuum without disconnecting the main joint. As a single piece weighing 0,105 kg, the flask from manufacturer Rettberg belongs to established Schlenk line equipment. It finds application in organic synthesis, organometallic research and distillation setups requiring reliable air exclusion. Chemical resistance and thermal stability of borosilicate glass 3.3 support long service under typical laboratory solvent and heating conditions.

Questions about Nitrogen flask, 100 ml, socket size 29/32, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 100 ml, socket size 29/32, side PTFE-valve 0 - 3 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
