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
