|Particle Size Standards --- LS Series|
These NIST traceable particle standards have been designed to calibrate or validate particle counting systems. They will be delivered in a 5ml or 20ml dropper-tipped-bottle and with a certificate of calibration.
Each particle size has a certain solids content which leads to a particle concentration below a significant coincidence when applying the dosage recommended in the accompanying certificate (for example 2 drops of the calibrant added to 40ml of pure water leads to 2000-6000 part./ml).
The advantage of this series is that the calibration itself can be started immediately without plenty of trial-and-error dosages until a coincidence-free measurement is possible. This saves time, calibrant and money!
Available certified particle diameters: 1,0µm - 80µm
