COUNT-CAL* Count Precision Standards
標準顆粒數量3000 particles/mL ± 10%. Composition : Polystyrene
適合液體微粒子計數器的校正, 並符合NIST的追溯。USP 788.
Quantity 6 x 25mL bottles per pack
COUNT-CAL is a ready to use precision standard designed for regular use in liquid particle counters to verify instrument calibration before each use. This assures the reproducibility of the particle counter by permitting a continuous record of its performance using a NIST* traceable microsphere suspension with a precise concentration.
■Polystyrene microspheres are suspended in an ultra clean diluent
■Concentration is optimized for use in light obscuration particle counters and other low concentration counting applications
■Diameters are traceable to the Standard Meter through the National Institute of Standards and Technology (NIST)
■CC10 and CC25 are ideal for USP 788 and 788 interim testing
