Nutraceuticals | Uses for Supercritical Fluids

Compared to traditional extraction methods, natural supercritical CO2 extraction has many benefits and is Generally Recognized As Safe (GRAS). Supercritical CO2 extraction eliminates exposure of the natural product to oxygen during the process and thus reduces oxidation of sensitive bioactive compounds. It also is a low temperature operation that does not promote thermal degradation of sensitive nutraceutical compounds . In addition, when the supercritical CO2 extract is depressurized, there are

Rockwell hardness tester

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.[1] There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc.,
