600-GA1000
PQ Check Standard, 10 µm Particle Count and Size Standard
- Volume: 1L
- Each unit will nominally contain approximately 100,000 particles/mL of 10 µm Polystyrene Latex (PSL) spheres
- Product batch will be ± 10% of the nominal concentration; individual standard bottles will be certified ± 22% of the mean concentration and particle sizes are certified ± 5% of the standard size (± uncertainty)
- The Certificate of Analysis includes actual concentration testing data and mean size.

Batch Certified Clean LP Bottles
Designed as a clean sample bottle for most particulate testing applications, this container is suitable for most sample fluids. Before filing, please consult material compatibility charts for HDPE and PP for your specific material.
Using an appropriate sampling plan, a sample set of bottles from each batch is filled with particle-free water and tested. The entire batch of bottles is certified clean if the mean particle count ≥ 0.7 µm in that sample set is not more than 10 particles/mL.
Individually Certified Clean LP Bottles
Designed as a clean sample bottle for most particulate testing applications, these HDPE containers with PP caps are suitable for most sample fluids. Before filing, please consult material compatibility charts for HDPE and PP for your specific material.
By ordering this option, each bottle is filled with particle-free water and tested individually. The bottle is certified clean if the mean particle count ≥ 0.7 µm is not more than 10 particles/mL.
Includes individual C of A for each bottle along with particle test report.

PQ Check Standard, 5 & 10 µm Bi-Mix, USP <729 > Method 2 with Automatic Dilution
- Designed specifically with USP <729> requirements in mind, prior to executing the “”Method 2″” SPOS PFAT-5 test, this standard is used to verify the performance of a Single Particle Optical Sensing (SPOS) particle counter equipped with an automatic dilution system.
- Standard material: NIST traceable size Polystyrene latex (PSL) spheres.
- Nominal sizes and concentrations of standard particles:
- 5 µm PSL – 400,000 particles/mL
- 10 µm PSL – 200,000 particles/mL
- Product batch will be ± 10% of the nominal concentration; individual standard bottles will be certified ± 22% of the mean concentration and particle sizes are certified ± 5% of the standard size (± uncertainty)
- The Certificate of Analysis includes actual concentration testing data and mean size.
