Description
Ground joint adapter in silicone, A45 to NS 29/32, provides a flexible connection interface for akku-drive® laboratory dispensers. The silicone construction supports a secure ground-joint fit from A45 to the standard NS 29/32 taper, helping laboratories couple bottles or vessels to the instrument during liquid handling. Offered as one piece with a net weight of 0,040 kg and a gross weight of 0,042 kg, the adapter is compact and easy to store or exchange. Packaging measures approximately 0,15 m depth, 0,08 m width and 0,06 m height. Manufactured in Germany and available from manufacturer Hirschmann, it is intended for use with akku-drive® systems in analytical, preparative and routine laboratory settings. The ground-joint geometry follows common European glassware standards, facilitating integration with existing NS 29/32 glassware. Ideal for labs that need a dedicated silicone adapter for dispenser-to-vessel connections without modifying the instrument itself.

Questions about GROUND ADAPTER, SILICONE, A45 COMPLIANT WITH NS 29/32
What is this article?
GROUND ADAPTER, SILICONE, A45 COMPLIANT WITH NS 29/32 is the article on this page. Luminix Health distributes Hirschmann 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.
