Description
PTFE stirrer plug for standard ground joints NS 24/29 is a laboratory accessory that seals and guides a stirrer shaft in glass apparatus. Made entirely of chemically resistant PTFE, it matches glass joints 24/29, accepts shafts of Ø 10 mm and measures 70 mm in length. The inert polymer surface supports smooth rotation while limiting chemical interaction during synthesis, extraction or sample work-up. Supplied as one piece with a weight of 0,067 kg, the plug fits standard ground-joint glassware used with overhead stirrers and related laboratory appliances. From manufacturer Bohlender, this fitting is intended for accessories-for-agitators applications where a closed yet freely rotating connection is required. PTFE construction provides broad media compatibility and low friction for continuous or intermittent stirring in research, development and quality-control environments. The compact design integrates cleanly into existing labware setups without altering joint geometry, helping maintain system integrity around the stirring axis throughout routine laboratory operations.

Questions about PTFE stirrer plug for standard ground-, glass joints 24/29, for Ø 10 mm, L 70 mm
What is this article?
PTFE stirrer plug for standard ground-, glass joints 24/29, for Ø 10 mm, L 70 mm is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
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.
