Meet the unique and demanding requirements of the contamination control laboratory in modern industries with Thermo Scientific™ Ezy-Cal™ Count Precision Size Standards, easy-to-use liquid particle count controls at 2000 particles per mL. Designed for regular use in liquid particle counters to verify instrument calibration before each use, standards assure reproducibility of the particle counter by permitting a continuous record of its performance using a NIST™-traceable microsphere suspension with a precise concentration.

  • Ready-to-use (no dilution required) particle size standard for validating optical particle counters
  • Magnetic stir bar included in each bottle for clean, convenient and direct sampling
  • Aqueous suspension medium contains a combination of dispersing agents to keep particles from clumping or sticking to flow surfaces in the particle counter
  • Particle diameters traceable to the Standard Meter through the National Institute of Standards and Technology

Recommended for:

Checking the calibration of liquid particle counters.
