Description
Schlenk tube, 100 ml with socket NS 14,5/23 is a specialised laboratory vessel designed for the safe manipulation of air- and moisture-sensitive substances under inert gas or vacuum. Made from borosilicate glass 3.3, the tube features a lateral glass stopcock equipped with a solid glass plug of NS 14,5/2,5 mm bore and a 9 mm olive for hose attachment. The 100 ml nominal capacity is well suited to preparative-scale work, including solvent drying, reagent storage, vacuum transfers and reaction monitoring within a Schlenk-line setup. Compatibility with conventional ground-joint apparatus is assured by the NS 14,5/23 socket. Net weight is 0,128 kg. Produced by manufacturer Rettberg, this Schlenk apparatus combines robust construction with the excellent chemical resistance and thermal-shock performance of borosilicate glass 3.3. The side stopcock enables convenient isolation of contents while allowing connection to vacuum or inert-gas manifolds. Suitable for organometallic synthesis, catalysis studies and other air-free laboratory techniques, the tube supports reliable and reproducible handling of reactive intermediates in research and teaching environments.

Questions about Nitrogen tube, 100 ml, socket size 14,5/23, side stopcock 2,5 mm bore,
What is this article?
Nitrogen tube, 100 ml, socket size 14,5/23, side stopcock 2,5 mm bore, 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.
