Description
Flexible PTFE ground joint sleeve 24/29 is a laboratory sealing sleeve for standard ground glass joints. Made from polytetrafluoroethylene, it forms a grease-free interface between male and female joints and is self-lubricating, so no joint grease is required. The flexible construction fits the 24/29 joint size and is intended for low and medium vacuum work. Thermal resistance reaches 280 °C, supporting heated assemblies as well as ambient setups. A pack contains 10 pieces; net weight is given as 0,005 kg. These sleeves from manufacturer Labbox help protect ground surfaces, limit grease-related contamination and ease assembly or dismantling of glassware trains used in synthesis, distillation and vacuum filtration. PTFE’s chemical inertness suits many common laboratory media, while the collar-style sleeve format aligns with typical manschette and ground-joint sealing practice. Use them wherever a clean, reusable PTFE seal on NS 24/29 joints is preferred over traditional greases, especially when moderate vacuum and elevated temperature must be combined without compromising joint integrity.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Flexible PTFE sleeves for 24/29 glass joints, 10 pcs
What is this article?
Flexible PTFE sleeves for 24/29 glass joints, 10 pcs is the article on this page. Luminix Health distributes Labbox 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.
