Measuring probes for analyzing liquids

There are a number of special probes available for your Force Tensiometer – K100SF, in addition to the standard probes for the Du Noüy ring method and the Wilhelmy plate method, for example for analyses using only small sample volumes.

PL0901 – Standard measuring probe for the Wilhelmy plate method

PL0901 – Standard measuring probe for the Wilhelmy plate method
Wilhelmy surface tension measurement using PL01

The PL0901 is our proven plate geometry for measuring the surface and interfacial tension using the Wilhelmy plate method. The dimensions of the plate comply exactly with the form specified in international standards and thus enable a high level of repeatability for the analyses. As the plate is made of the precious metal platinum it has an extremely high surface free energy and therefore also the required excellent wetting properties. These are further optimized by its homogenously roughened surface.

A simple clamping mechanism allows especially fast insertion of the plate. Its safe storage is assured through a high-quality protective box provided.

A PLC0901 version of the plate with a certificate from an independent testing institute is also available.

PL0902 – Wilhelmy plate measuring probe for small sample volumes

PL0902 – Wilhelmy plate measuring probe for small sample volumes

The PL0902 measuring probe enables measurement of the surface tension with the Wilhelmy plate method in the case of small sample volumes. It is the same size (wetted length) as our standard PL0901 plate and is also ideally wettable being made from the same precious metal platinum, but it is rolled cylindrically so it only requires a small 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.

PL0903 – Rod-shaped probe for measurements with the Wilhelmy method

PL0903 – Rod-shaped probe for measurements with the Wilhelmy method

The rod-shaped probe PL0903 can be used as an alternative to the rolled PL0902 for measuring the surface tension using the Wilhelmy method with small sample volumes. Thanks to its small diameter it is possible to carry out measurements in small vessels, but unlike the PL02 it also enables measurement of the interfacial tension. The rod is made of the ideally wettable precious metal platinum. A high-quality protective box is provided for its safe storage.

The scope of delivery of the rod 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.

RI0901 – Standard measuring probe for the Du Noüy ring method

RI0901 – Standard measuring probe for the Du Noüy ring method

The RI0901 ring is our high-precision standard measuring probe for surface and interfacial tension using the Du Noüy ring method. The wire ring made of a platinum-iridium precious metal alloy is ideally wettable; the hardness of the iridium makes the measuring probe especially robust. The ring geometry is only connected to the shaft at two junctures, so that any disturbing influences on wetting are negligible.

A simple clamping mechanism allows especially fast insertion of the ring. Its safe storage is assured through a high-quality protective box provided.

An RIC0901 version of the ring with a certificate from an independent testing institute is also available.

RI0902 – Du Noüy ring measuring probe for small sample volumes

RI0902 – Du Noüy ring measuring probe for small sample volumes

The special measuring probe RI0902 is used for measuring the surface tension with the ring method where only small sample volumes are available. Measurements with volumes as of 1 mL are possible thanks to the reduced diameter of the ring.

Like the standard RI0901 ring, the RI0902 is also made of a platinum-iridium alloy so its combines ideal wettability with the necessary metal hardness. Its design with only two contact points between the ring and the shaft and its shape accuracy ensure a high level of precision. A special vessel for small sample volumes is included in the scope of delivery as well as a high-quality protective box in which it can be safely stored.
