The Abbemat HT refractometer is a Heavy Duty line refractometer from Anton Paar. It is designed for work in harsh environments and for special
applications requiring high temperatures or vertical operation to avoid sedimentation on the prism. They feature a hermetically sealed stainless steel housing and no display in order to withstand spillage and dirt.

Benefits of Abbemat HT at Solvent deasphalting
The refractive index of waxy raffinates at temperatures from 80 °C to 100 °C can be used for quality control and/or process control of the deasphalting process. As long as the melting point of the sample is at least 10 °C below the test temperature, measurements at lower temperatures are possible, too.
