Overcoming Sedimentation and Agglomeration in 2.0 Micron PSL Sphere Calibration
The physical behavior of monodisperse 2.0-micrometer polystyrene latex suspensions is governed by a critical hydrodynamic transition in which gravitational sedimentation, dictated by Stokes’ Law, rapidly supersedes Brownian kinetic diffusion, while short-range London-van der Waals attraction overcomes electrokinetic double-layer repulsion, accelerating irreversible agglomeration. Fluid Dynamics, Aerosol Physics, and Colloidal Mechanics of the 2.0 µm Boundary Calibrating […]
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, […]
