[Made in Japan] Particle Size Calibration Standard Particles 200nm 'Uni-spheres'

For the calibration of measuring instruments! Traceable particle size calibration standard particles from AIST. These particles have a very narrow particle size distribution and do not contain surfactants.

"Uni-spheres" are spherical polystyrene-based latex particles with excellent uniformity, suitable for calibration and precision management of particle size measurement devices, as well as for validating particle size measurement methods. The particle size is determined using the particle size calibration service of the National Metrology Institute of Japan (NMIJ) and is traceable to the International System of Units (SI). 【Specifications】 ■ Form: Aqueous dispersion of polystyrene particles (containing 0.5 mg/ml of sodium azide) ■ Volume: 10 ml ■ Solid concentration: 10 mg/ml *For more details, please download the PDF or feel free to contact us.
