Description
Straight valve stopcock for burettes 2-10 ml with PTFE spindle and clear glass is a precision accessory for volumetric titration setups. Made from borosilicate glass 3.3 and featuring DURAN® glass, the straight valve design supports reliable flow control on smaller burettes in the 2-10 ml range. The PTFE spindle provides smooth operation and chemical resistance at the sealing interface, which is important for routine analytical work. Supplied as 1 pc with a net weight of 0,047 kg, this stopcock is intended as replacement or original equipment for matching clear-glass burettes. From manufacturer Hirschmann, the component suits laboratory titration lines where a straight valve geometry and PTFE spindle are specified. Clear glass construction aids visual monitoring of liquid paths during filling and dispensing. Use it to maintain consistent stopcock performance on 2-10 ml burettes in teaching, quality control and general analytical laboratories that rely on DURAN® borosilicate glassware.

Questions about STR. VALVE STOPCOCK 2-10 ML, PTFE SPINDLE, CLEAR GLASS
What is this article?
STR. VALVE STOPCOCK 2-10 ML, PTFE SPINDLE, CLEAR GLASS is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Laboratory glass bottles, inside Bottles & containers, in Labware.
A laboratory glass bottle is borosilicate or soda-lime, with a stated capacity and a neck for a screw cap or a ground stopper. Glass is the choice when the liquid attacks a plastic, or when the bottle will be heated or autoclaved.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
