Safe Handling and Unboxing Guide for Particle Standards
Unlike standard laboratory supplies, unboxing a NIST-traceable particle standard is a high-stakes procedure where a single speck of ambient dust can instantly ruin a critical calibration baseline. The moment you break the shipping seal, sensitive PSL spheres face immediate risks from static aggregation, thermal shock, and cleanroom cross-contamination. Safeguarding your data accuracy requires a strict, […]
Should I buy individual particle size standards or a full set of microspheres?
When buying particle size standards, the key question is: should you choose individual microspheres or a full set? If you’re testing a specific size range, individual standards are a cost-effective, targeted option. But for calibration, quality control, or comparisons across multiple sizes, a full set provides broader coverage, consistency, and stronger benchmarking. In this article, […]
