Description
Ensure accurate and convenient calibration of laser particle counters with Thermo Scientific™ 3K/4K Series Particle Counter Standards. Compared with our 3000 and 4000 Series products, this product line is precisely diluted for immediate use in laser particle counters with minimal time-consuming concentration adjustments.
Features:- Suspensions of monodisperse polystyrene spheres for use in airborne or liquid particle dispersion systems
- Particle diameters traceable to the Standard Meter through the National Institute of Standards and Technology (NIST)
- Accurately calibrates or checks performance of laser particle counters used in cleanrooms and other contamination monitoring applications
- Particles prepared as low residue aqueous suspensions for minimal background interference
