Description
Adapter BS 29 to HNS 19/26 is a laboratory glass transition piece that connects a ball joint to a standard ground socket for flexible apparatus assembly. It converts from a spherical ball joint ball S 29/15 to an NS socket 19/26, enabling secure coupling between ball-joint and conical ground-joint components in distillation, reaction or vacuum setups. The compact adapter supports leak-resistant joins when properly greased and clamped, helping laboratories combine apparatus sections that use different joint systems. With a net weight of 0,032 kg, it is a lightweight, single-piece fitting suited to routine glassware configurations. This transition piece from manufacturer Witeg is intended for general laboratory use wherever a ball-to-NS changeover is required. Clear joint sizing (ball S 29/15 to sleeve NS 19/26) simplifies selection and matching to existing glassware. Supplied as one piece, it is a practical interconnect for modular setups in research, teaching and quality-control laboratories that rely on standardized ground and ball joints.

Questions about Spherical-conical adapter ball S 29/15
What is this article?
Spherical-conical adapter ball S 29/15 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
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.
