Whitehouse Scientific will be showing its complete range of particle size calibration standards in stand 8-204 at Powtech 2004, to be held in Nürnberg, Germany, March 16-18. Available standards include polydisperse, monodisperse and sieve calibration. New to the range is the latest sub-micron polydisperse standard, available as a dry powder ready for dispersion in a dropping pipette bottle. A new multi-pack monodisperse selection has been produced to provide 10 individual sizes from 20-130 microns. Additionally, the sieve calibration standards have been extended to cover sieve diameters from 200 mm down to 40 mm.
