Description
Discharge valve (AL2O3) is a precision laboratory valve component with a valve seat and ball made of high-purity ceramic (Al2O3 99,7%) and a spring of Hastelloy. It is intended as a discharge (outlet) valve for bottle-top dispensers and related liquid-handling systems, supporting accurate, chemically robust fluid release in routine titration, media dispensing and analytical preparation. The ceramic seat and ball combination is chosen for hardness and chemical durability, while the Hastelloy spring contributes corrosion resistance in demanding reagent environments. Compatibility covers opus®, cermaus®, ceramus® classic from 25 ml, solarus® and ceramus® HF instruments, making the part suitable as a service or replacement element within those platforms. Offered as a single piece with a net weight of 0,006 kg, this discharge valve from manufacturer Hirschmann helps maintain dispenser performance where high-purity ceramic contact surfaces are required. Compact packaging dimensions support easy storage of spare parts beside the corresponding dispenser systems in research and quality-control laboratories.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about DISCHARGE VALVE (AL2O3)
What is this article?
DISCHARGE VALVE (AL2O3) is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
Which category should I open next?
