200nm Particle Size Calibration Standard 'Uni-spheres'
[Made in Japan] Traceable particle size calibration standard particles from AIST (National Institute of Advanced Industrial Science and Technology). These particles have a very narrow particle size distribution and do not contain surfactants.
"Uni-spheres" are newly developed particle size calibration standard particles based on soap-free polymerization technology cultivated in the development of latex for in vitro diagnostic reagents. They are uniform, spherical polystyrene-based latex particles that can be used for the calibration and precision management of particle size measurement devices, as well as for the validation of 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 ■ CV value (reference): 1.0% ■ Density (reference): 1.0540 g/cm3 ■ Particle mass (reference): 4.916 fg *For more details, please download the PDF or feel free to contact us.
