Description
PTFE stirrer plug for standard ground joints NS 29/32 is a laboratory fitting that guides and seals a stirrer shaft in ground-joint glassware. Fabricated from chemically resistant PTFE, it is sized for glass joints 29/32, accepts shafts of Ø 8 mm and has a length of 74 mm. The inert contact surface enables low-friction rotation while protecting the joint interface during chemical synthesis, blending or process development work. Delivered as a single piece weighing 0,095 kg, the plug pairs with overhead stirrers and standard laboratory appliances that use NS 29/32 connections. From manufacturer Bohlender, this component belongs to the accessories-for-agitators range and supports closed-system stirring without binding the shaft. PTFE offers wide chemical compatibility for research, analytical and quality-control laboratories that rely on durable polymer labware. Its defined dimensions allow straightforward installation into existing glass assemblies, helping maintain alignment and sealing performance around the stirring axis during everyday laboratory use.

Questions about PTFE stirrer plug for standard ground-, glass joints 29/32, for Ø 8 mm, L 74 mm
What is this article?
PTFE stirrer plug for standard ground-, glass joints 29/32, for Ø 8 mm, L 74 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.
