Description
Concentrated polymer microsphere suspensions at 10% w/w, with a narrow monomodal distribution (CV ≤ 5%) and an accurately measured diameter, for applications that need large amounts of material but not SI traceability. Diameters range from below 0.1 to above 100 µm and are usually not round values: for example 0.281 µm for a 0.280 µm nominal size. The most common use is filter testing, HEPA included, for exclusion limits and loading capacity; they also serve in sedimentation and centrifugation experiments and as calibrated spacers. 15 or 100 mL bottles, 36 month shelf life at room temperature.
Applications
- Filter testing (HEPA included): exclusion limits and loading capacity
- Sedimentation and centrifugation experiments
- Calibrated spacers in manufacturing processes
- Research in materials science, diagnostics, biotechnology and environmental studies
- Analytical instrument development

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.
