RM/X Foil Stamp Set
RM/X Foil Stamp Set

The determination of bound styrene via refractive index, in styrene-butadiene rubber (SBR) can be an almost impossible task. The air gap between the sample and the prism of the cell must be avoided to ensure a reliable measurement. This is a common problem when measuring the refractive index of foils, gums and granulates.

Foil Stamp Set for Refractometers

The RM/X Foil Stamp Set from METTLER TOLEDO pushes foils, gums and granulates samples on the prism of the refractometer, ensuring full contact of the sample with the cell during measurements. With this technique of pressing the sample into the prism, there is no air gap between the sample and the prism. Using our innovative tool, you will get accurate and repeatable results, saving time in the process, as there is no need to clean the cell after each measurement cycle; contrary to what happens when you use contact liquids.

This application note covers the foil stamp method, using foils and granulates in the determination of bound styrene in styrene-butadiene rubber (SBR).
