Many insoluble materials, mixed with Potassium Bromide, can be formed in a die under pressure into pellets or wafers for quantitative and quali tative analysis. The CLP supplies the pressure — un to 40.000 lbs., it needed. This specific LISP is only one of the ways this versatile laboratory assist ant meets the challenge of research and development. Some of the many uses are'. u* Dehydrating v* Pressing out various oils, stéarines and waxes ι * * Pressure filtering of thick fluids t* Compression tests i«* Fatty acid determinations \* Plastic molding, forming and blocking L** Embossing and forcing le* Pressing mother liquors from crystals i ^ Extracting Vaccines and Viruses The Standard (12-ton) CARVER LABORA TORY PRESS complete with Gauge $345.00 (illustrated) 20 Ton Models also available additional Standard Accessories for other applica tions can be supplied.
