Superfix joint clip NS 34/35-34/45 is a complete ground-joint securing assembly for laboratory glassware in the NS 34/35 to NS 34/45 size range. The system comprises a white protective cap, a threaded core inner part and a clamping O-ring, delivering reliable fixation of conical ground joints during routine experimental work. Designed for standard laboratory conical joints, the clip maintains secure coupling of glass apparatus without additional fastening hardware. Supplied by manufacturer Witeg as a ready-to-use set, the lightweight assembly (net weight 0,026 kg) is practical for multi-setup chemistry and analytical laboratories. Each pack contains 5 pieces, supporting efficient stocking and replacement. The combination of cap, internal threaded element and elastic O-ring clamp helps preserve joint integrity under typical laboratory conditions while remaining simple to apply and remove. Suitable for everyday glassware connections in teaching, research and quality-control environments where dependable NS joint retention is required.

Questions about SUPERFIX- Safety devices ST 34
What is this article?
SUPERFIX- Safety devices ST 34 is the article on this page. Luminix Health distributes Witeg 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.
