NanoMicro offers count standard particles with accurate particle size and particle count obtained by accurately diluting particle size standard particles. They are mainly used for instrument calibration and performance evaluation of laser particle counters in clean rooms and their pollution monitoring fields. This range of products has been precisely diluted and supplied as a suspension in 10 mL dropper bottles for ease of use. Products are available in particle sizes ranging from 1.0 – 100 μm, with particle sizes traceable to NIST standard reference materials.
