Aqueous Particle Suspension Standards For NIST traceable light-scattering monitor calibration and validation 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.   Item Part Number Size Price Quantity Add to Cart Conductivity Standard Precision 100 us/cm 500mL pouches 3P-0100-2 1 POUCH $47.50   Conductivity Standard 25 mS/cm 3P-025K-2 500 mL Pouch $47.50   Conductivity Standard Precision 1 ms/cm 500mL pouches 3P-001K-2 1 POUCH $47.50   Conductivity Standard Precision 10 ms/cm 500mL pouches 3P-010K-2 1 POUCH $47.50   Conductivity Standard Precision 100 ms/cm 500mL pouches 3P-100K-2 1 POUCH $47.50   Conductivity Standard Precision 147 us/cm 500mL pouches 3P-0147-2 1 POUCH $47.50   Conductivity Standard Precision 447 us/cm 500mL pouches 3P-0447-2 1 POUCH $47.50   Conductivity Standard Precision 718 us/cm 500mL pouches 3P-0718-2 1 POUCH $47.50   Conductivity Standard Precision 1413 us/cm 500mL pouches 3P-1413-2 1 POUCH $47.50   Conductivity Standard Precision 2 ms/cm 500mL pouches 3P-002K-2 1 POUCH $47.50   Conductivity Standard Precision 5 ms/cm 500mL pouches 3P-005K-2 1 POUCH $47.50   Conductivity Standard Precision 12.88 ms/cm 500mL pouches 3P-12.88K-2 1 POUCH $47.50   Conductivity Standard Precision 20 ms/cm 500mL pouches 3P-020K-2 1 POUCH $47.50   Conductivity Standard Precision 53 ms/cm 500mL pouches 3P-053K-2 1 POUCH $47.50   Conductivity Standard Precision 58.7 ms/cm 500mL pouches 3P-058K-2 1 POUCH $47.50   © COPYRIGHT, AURICAL COMPANY, 2007 - 2010, ALL RIGHTS RESERVED.
