Description
neoChoice thread adapter borosilicate 3.3, GL 25, sleeve NS 29 is a precision glass connector that links threaded laboratory bottles to ground-joint apparatus. Manufactured from chemically resistant borosilicate glass 3.3, it provides a stable, inert interface for routine organic and analytical work. The GL 25 thread mates with matching screw couplings, while the NS 29 sleeve engages standard conical joints on rotary evaporators, distillation trains and related glassware. Size-dependent screw couplings from the E-2920 series are required for a secure seal. This configuration from manufacturer neolab - Labor supports quick bottle changes without compromising joint integrity or introducing metallic contact surfaces. The single-piece glass body withstands typical laboratory solvents and thermal stress associated with evaporation and reflux setups. Supplied as one piece, the adapter is intended for laboratories that need a reliable, reusable bridge between screw-cap vessels and classical ground-joint systems. Clear dimensional coding (GL 25 / NS 29) simplifies selection and inventory control across multi-user labs.

Questions about neoChoice Gewindeadapter Borosilikat 3.3, GL 25, Hülse NS 29
What is this article?
neoChoice Gewindeadapter Borosilikat 3.3, GL 25, Hülse NS 29 is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Raccords pour tuyaux, adaptateurs & raccords, inside Tubes, tuyaux et raccords, in Matériel de laboratoire.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
