- High Accuracy
- Inert silica particles for stability
- Gravimetrically traceable NIST weight (mass) standards
- Levels where needed 0.0 - 1,000 ppm
Aurical Company has developed techniques for preparation of aqueous particle suspension standards with well-defined range of particle size. Also, Aurical has developed techniques to maintain suspension for sufficient time allowing convenient instrument calibration. These standards are made from particles which have been selected in the range including 0.00 to 1000 ppm. Tis range was chosen to favor calibration used with centrifuges separating cell debris from broth in postfermentation bioprocessing. Aurical Company continues the tradition of excellence. The standard levels below are particularly good to provide tabular calibration for the Optek-Danulat brand turbidity monitors.
