Slim and functional - the Ring Shear Tester RST-XS is designed with industrial requirements in mind. With a wide range of features, the Ring Shear Tester offers unprecedented functionality, precision and flexibility.

The RST-XS is an easy to operate, computer-controlled tester for the precise determination of the flow properties of fine-grained powders and bulk solids. It is appropriate especially for those industries and research institutions, which deal with fine-grained materials, or which have only limited amounts of powders for testing, e.g. the pharmaceutical industry, food industry, chemical industry and many others.

The tester measures not only the flowability, but also other physical quantities like the internal friction of a powder, the bulk density, the time consolidation (caking), and wall friction. It is the appropriate tester for your requirements concerning product characterization, quality control, comparative tests, process optimization, and more.

The main difference between the RST-XS and our Ring Shear Testers RST-01.01 and RST-01.pc is, besides the somewhat easier operation, the size of the tester: The width is about 600 mm, the weight is approx. 40 kg. The standard shear cell requires a powder specimen of only about 30 ml, cells of other volumes are available (smallest cell with specimen volume smaller than 10 ml). Therewith the tester is well-suited for the application in the Pharmaceutical Industry, where usually only small amounts of powders are available for testing. According to its smaller dimensions, also the price of the RST-XS is smaller than the price of the automatic Ring Shear Tester RST-01.pc.
