Description
Check valve in borosilicate glass with plastic protection is a laboratory spare part intended for LABMAX liquid-handling systems. The valve body is made of borosilicate glass and fitted with a plastic protective element to reduce the risk of mechanical damage during handling and routine instrument operation. Supplied as one piece, it serves as a directional flow component within the LABMAX accessory range, supporting controlled liquid paths in dispensing or related laboratory workflows. Net weight is 0,01 kg, keeping the part compact for installation and storage among other instrument spares. Borosilicate construction offers the thermal and chemical stability expected of laboratory glassware, while the plastic protection adds a practical safeguard for everyday use. This check valve from manufacturer Witeg is listed among accessories and replacement parts for laboratory devices and is specified for LABMAX instruments. It is suited to laboratories that maintain original-equipment spare inventories and need a matching borosilicate check valve with protective covering for continued reliable operation of their dispensing setup.

Questions about Check valve
What is this article?
Check valve is the article on this page. Luminix Health distributes Witeg 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.
