Are the standards traceable?
Yes: mean diameter, standard deviation and uncertainty are traceable to NIST and the International System of Units (SI) and stated on the certificate of every lot. The ISO/IEC 17025 series is certified by an accredited metrology laboratory.
Which control do I need for USP <788>?
For subvisible particle counting in injectables, use the PharmaCount controls: the USP <788> set for routine verification, the 3M and PC sets for single diameters. For USP <729> there is PharmaCount BiCal.
Can I order a diameter I do not see?
Yes: other diameters, concentrations and dyes are available on request. Tell us the value you need and we will send a quote.
How do I see the prices?
List prices per pack, excluding VAT, are shown after signing in to the customer area. With the quote request we confirm price, availability and delivery time.
