Particle Sizing/Conversions

Custom particle size classification service:

We offer custom particle size classification services to grade your particles, powders or aggregates to size. We can grade your particles to any size between 15um (0.00059 inches) and 5.6mm (0.220 inches). The table below shows cut sizes that we can currently grade to. Custom cut sizes are available by request.

Do you need to measure your particles for size and particle size distribution? We offer Analytical Services.

We specialize in small runs but can also handle larger quantities. Contact us for a quote.
