Description
Hoffmann tubing pinchcock CLF-HKRGZ is a compact LabJaws clamp designed for controlled pinching and securing of laboratory tubing. Constructed from nickel-plated steel, it delivers high tensile strength and reliable durability at a practical price point for routine lab work. Key dimensions include a width of 37 mm, a height of 62 mm and a maximum clamping span of 17 mm, with a net weight of 0,5 kg. These proportions make the pinchcock suitable for precise flow control and temporary closure of flexible tubing lines. Drawn from the LabJaws range of manufacturer Ohaus, it forms part of a broad selection of more than 85 clamp variants offering different grip widths, profiles and types. LabJaws clamps help hold glassware and irregular objects securely, supporting safer laboratory setups and reducing the chance of accidental spills or disconnections. Supplied as a single piece, the CLF-HKRGZ integrates easily into existing stands, frames and tubing arrangements used in analytical and preparative workflows.

Questions about Clamp, Flow Control, Hosecock, CLF-HKRGZ
What is this article?
Clamp, Flow Control, Hosecock, CLF-HKRGZ is the article on this page. Luminix Health distributes Ohaus 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.
