- 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.
