Description
Schlenk tube, 100 ml, socket NS 29/32 is a graduated laboratory vessel for safe handling of air- and moisture-sensitive compounds under inert atmosphere or vacuum. Constructed from borosilicate glass 3.3, it is fitted with a lateral high-vacuum PTFE valve featuring a fine thread that permits precise control of the valve passage between 0 and 8 mm, plus an olive of Ø 8 mm for secure connection of vacuum or inert-gas tubing. The larger NS 29/32 ground-joint socket ensures compatible sealing with corresponding Schlenk-line components and ground-joint glassware. Graduation markings allow convenient volume estimation during transfers and reactions. This Schlenk apparatus from manufacturer Rettberg is intended for synthetic organic and inorganic chemistry, organometallic work and vacuum-line applications where robust chemical resistance and vacuum integrity are required. Borosilicate glass 3.3 supplies the necessary thermal stability for everyday laboratory use, while the side-arm PTFE valve geometry supports efficient inert-gas operations, solvent handling and sample storage under protective atmosphere. Supplied as a single piece for small-scale inert-atmosphere work.

Questions about Nitrogen tube, 100 ml, graduated, socket size 29/32,
What is this article?
Nitrogen tube, 100 ml, graduated, socket size 29/32, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labware.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
