Description
Flexible PTFE ground joint sleeve 29/32 is a laboratory sealing sleeve for standard ground glass joints of the 29/32 size. Fabricated from polytetrafluoroethylene, it delivers a self-lubricating seal so joint grease is unnecessary, reducing residue and simplifying cleaning. The flexible design seats reliably on NS 29/32 connections and is suitable for low and medium vacuum applications. Resistance up to 280 °C allows use in heated apparatus as well as room-temperature setups. Each pack holds 10 pieces, with a stated net weight of 0,006 kg. Offered by manufacturer Labbox, these sleeves support clean joint sealing in organic synthesis, distillation, reflux and vacuum filtration glassware, helping protect ground surfaces and speed assembly or disassembly. PTFE chemical resistance and the collar-style manschette format make them a practical alternative to greased joints when moderate vacuum, thermal load and contamination control matter. Choose this 29/32 variant wherever a reusable, grease-free PTFE interface is required on larger standard taper joints.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Flexible PTFE sleeves for 29/32 glass joints, 10 pcs
What is this article?
Flexible PTFE sleeves for 29/32 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.
