Description
Mohr pinchcock 50 mm is a compact tubing clamp used to control or interrupt liquid flow in flexible laboratory tubing. The clamp is manufactured from brass with a nickel-plated finish, giving a durable metal construction suited to repeated open-and-close operation on the bench. With a 50 mm size, it fits common laboratory hose diameters for gravity-feed lines, simple dosing setups, and temporary shut-off during sampling or rinsing. Net weight is only 0,009 kg, so the pinchcock adds minimal bulk to tubing assemblies. Supplied as a single piece, it is easy to stock as a spare or to equip multiple workstations. This Mohr-type pinchcock from manufacturer Usbeck is a practical accessory for chemistry, biology, and general laboratory environments where reliable mechanical flow control is preferred over valves for short tubing runs. It supports clean, tool-free adjustment during routine experimental work and teaching demonstrations that rely on flexible hose connections.

Questions about Pinchcock Mohr 50 mm
What is this article?
Pinchcock Mohr 50 mm is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Graduated pipettes, inside Pipettes & pipette tips, in Consommables.
A graduated pipette delivers a chosen volume along a scale, to contain or to deliver as marked. Class A and class B differ in tolerance. A serological pipette is a different, usually plastic, article. Reading the meniscus and delivering correctly, blow-out or not, is printed on the pipette.
A pipette moves a measured volume. A volumetric pipette delivers one line. A graduated pipette delivers along a scale. A Pasteur pipette is an uncalibrated transfer. A piston pipette uses a tip, and the tip has to seal on that pipette. A filter tip adds a barrier so aerosol from the sample does not reach the piston. Serological pipettes are the long graduated tubes used with a controller. The volume and the fit are the specification. Piston pipettes are treated under ISO laboratory apparatus. In-vitro work also meets ISO in vitro diagnostic systems.
