Description
Schlenk tube, 25 ml, socket NS 14,5/23, lateral glass stopcock 2,5 mm and olive 9 mm is a laboratory glassware piece belonging to the Schlenk apparatus family. The tube features a nominal volume of 25 ml, a socket joint sized NS 14,5/23, and a lateral glass stopcock complete with solid glass plug of NS 14,5/2,5 mm bore together with a 9 mm olive. Made from borosilicate glass 3.3, it combines chemical inertness with thermal stability suitable for inert-atmosphere and reduced-pressure operations. Supplied as one piece with a net weight of 0,085 kg, the item originates from Germany and carries the registered trademark Rettberg ®. Reference to the manufacturer Rettberg appears once in the middle of the description. The standardised joint, stopcock bore and olive permit direct coupling to conventional Schlenk-line glassware, enabling controlled handling of air-sensitive compounds. This intermediate volume supports a range of synthetic and analytical procedures that demand reliable sealing and ease of manipulation within research laboratories.

Questions about Nitrogen tube, 25 ml, socket size 14,5/23, side stopcock 2,5 mm bore,
What is this article?
Nitrogen tube, 25 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.
