The PL22 measuring probe enables measurement of the surface tension using the Wilhelmy plate method in the case of small sample volumes. It is the same size (wetted length) as our standard PL21 plate and is also ideally wettable being made of the same precision metal platinum, but it is rolled cylindrically so it requires a smaller surface area of the liquid. A high-quality protective box is provided for safe storage of the plate.
The scope of delivery of the rolled plate also includes a measuring vessel that can be used flexibly for different sample volumes: The hollow has a capacity of 5 mL and the vessel has concentric rings on its underside that can be filled with up to 1.2 mL or up to 0.2 mL.
