Description
DURAN® Reducing adapter with socket NS 29/32 and cone NS 34/35 is a precision ground-glass joint component for linking laboratory apparatus that have different standard joint (NS) sizes. Fabricated from borosilicate glass 3.3, this reducing piece enables connection between a socket and a larger cone so that mismatched Schliff components can be assembled into a single functional setup. Adapters of this kind are essential in modular glassware systems where joint sizes must be bridged without loss of seal integrity or chemical resistance. Produced by manufacturer Duran/DWK Life Sciences under the DURAN® trademark, the item is supplied as one piece with a net weight of 0,033 kg. It is intended for routine laboratory applications including synthesis, distillation, extraction and general analytical work that require reliable joining of two parts with unequal Normschliff dimensions. The borosilicate glass 3.3 construction delivers the thermal and chemical stability expected of professional laboratory glassware, supporting flexible reuse of existing apparatus across different NS series.

Questions about DURAN® Reduction Adapter , socket/cone
What is this article?
DURAN® Reduction Adapter , socket/cone is the article on this page. Luminix Health distributes DWK Life Sciences 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.
