Description
Schlenk tube, 25 ml, socket NS 14,5/23 with lateral high-vacuum PTFE valve is a graduated laboratory vessel engineered for handling air-sensitive reagents. Constructed from borosilicate glass 3.3, the tube delivers the chemical durability and thermal performance expected in modern synthetic laboratories. A side-mounted HV PTFE valve with fine thread allows controlled adjustment of the valve passage from 0 - 8 mm, supporting reliable vacuum or inert-gas operations. The olive of Ø 8 mm provides a secure tubing interface for connection to Schlenk lines. Clear graduations assist volume assessment during transfers and reaction work-up. The NS 14,5/23 ground socket ensures compatibility with standard jointed glassware assemblies. Supplied as a Schlenk apparatus from manufacturer Rettberg, this 25 ml tube is well suited to intermediate-scale organometallic and inorganic procedures under inert atmosphere. Net weight is 0,049 kg, offering a convenient size for bench-top manipulation while maintaining robust vacuum-tight performance throughout repeated use cycles.

Questions about Nitrogen tube, 25 ml, graduated, socket size 14,5/23,
What is this article?
Nitrogen tube, 25 ml, graduated, socket size 14,5/23, 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.
Which category should I open next?
