• Duke Scientific Corporation's new COUNT-CAL™ is a cost effective and convenient product for validating particle counters. Packaged in single-use bottles, and intended to be sampled directly from the bottle, it eliminates the need for serial dilutions and extensive sample handling, thereby minimizing contamination. The particles are suspended in an ultraclean diluent and the concentration is optimized for use in light obscuration particle counters and other low concentration counting applications. The particle diameters are traceable to the Standard Meter through the National Institute of Standards and Technology (NIST).

  • Ezy-Cal™

    1.00
    This product line offers a series of ready-to-use standards for validating optical particle counters with no dilution and handling. The products are suspensions of monodisperse polymer microspheres in water with a concentration of 2000 particles per mL. A magnetic stir bar is included in each bottle for clean, convenient and direct sampling by instruments. This series of size standards is provided for setting or checking the calibration of channel thresholds or for checking the count precision of liquid-borne particle counters. Their certified diameters are traceable to NIST. They are packaged as 100mL screw-cap bottles, sufficient for four or five calibration procedures on most counters. The microspheres are composed of polystyrene, which has an index of refraction of 1.59 @ 589nm and a density of 1.05 g/cm3. The aqueous suspension medium contains a combination of dispersing agents, which help to keep the particles from clumping or sticking to flow surfaces in the particle counter. The EZY-CAL™ product line meets all of the unique and demanding requirements of the contamination control laboratory in modern industries.

  • PHARM-TROL™ Particle Count Control is a product containing National Institute of Standards and Technology (NIST) traceable size standards with a measured particle count. The product was developed to provide process control data for particle counting consistency and verification of size calibration. The ready-to-use precision standard is designed for regular use in liquid particle counters. This documents the reproducibility of the particle counter by permitting a continuous record of its performance using a microsphere suspension with a known concentration. The data provides documentation for internal or customer quality audits. The product is ideal for parenteral drug manufacturers seeking interim verification of USP <788> “Particulate Matter in Injections”, Light Obscuration Particle Count Test. PHARM-TROL™ is prepared with the same exacting procedures as the USP Count Reference Standard. The product is a 15µm polystyrene microsphere suspension packaged at 3800 particles per mL in 25mL single-use quantities. It is supplied in convenient 6 or 20 bottle sets.
