LWsphere®Si-Spacer is of very uniform particle size
The particle size and distribution of LWsphere®Si-Spacer were determined using internationally recognized testing instruments (Beckman Coulter Counter Multisizer) and methods. To ensure accurate results, each measurement is calibrated with NIST-traceable standard particles before each measurement.The coefficient of variation, CoefficientValue(CV)%(standarddeviation/averagediameter)x100, is controlled below 2.5%.
