PSL Spheres, HEPA Filter Efficiency, Leak Detection Tests
HEPA PSL Spheres, Polystyrene Latex Spheres, 5000 Series
5000 Series PSL are useful for applications such as ULPA filter and HEPA filter evaluation and testing, fluid mechanics research, dispersion studies and many other research and development projects. Bottle Volumes are greater with 100ml and 1000ml available as SPECIAL ORDER. These PSL particles meet the need for particulate materials with a variety of particle sizes and properties, and are useful for applications such as ULPA/HEPA filter evaluation and testing, fluid mechanics research, dispersion studies and many other research and development projects. They are not intended for use in instrument calibration or diagnostic reagents because they lack the exacting specifications needed for those applications. Particles of this series are of special interest for research in light scattering, micro-porous filter checking and aerosol particle generation. The polystyrene microspheres have a density of 1.05 g/ cm3 and a refractive index of 1.59 @ 589 nm. Particle diameters are measured by optical microscopy, photon correlation spectroscopy or light scattering. They are packaged as aqueous suspensions at 10% solids by weight.
The 5000 Series particles range from 30nm to 3.1 microns in size.
* 15 mL ("A" bottles) listed below are available for immediate purchase. 100 mL ("B" bottles) and 1000 mL ("C" bottles) are packaged to order; example (5003B and 5003C). Please allow 3-7 working days when ordering these fill volumes.
