Description
Rotilabo® sealing sleeve is a PTFE seal for standard ground joint 34/35 laboratory glass connections. Fabricated from polytetrafluoroethylene, it offers a chemically resistant sealing layer between larger taper joints commonly found on flasks, condensers, and intermediate adapters in distillation and extraction trains. The sleeve supports reliable joint seating while remaining compatible with many organic solvents and laboratory chemicals for which PTFE is specified. Packaged as one piece and weighing 0,010 kg, it is practical for dedicated positions on NS 34/35 apparatus and for spare-part stocking beside multi-joint setups. This Rotilabo® item from manufacturer ROTH SELECTION belongs to the ground-joint seals and ridged-sleeve labware group and is aimed at laboratories working with larger standard taper sizes. Apply it where a PTFE sleeve is preferred to assist sealing and to protect ground surfaces during frequent assembly and cleaning cycles. The single-unit pack keeps ordering simple for replacement or expansion of existing glassware configurations.
This article is part of Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Rotilabo®-sealing sleeve, PTFE, for ground joint 34/35, 1 unit(s)
What is this article?
Rotilabo®-sealing sleeve, PTFE, for ground joint 34/35, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
