CPS Instruments Inc. products

The CPS disc centrifuge separates particles by size using centrifugal sedimentation in a liquid medium. The sedimentation is stabilized by a slight density gradient within the liquid. The particles sediment through the density gradient inside a transparent rotating disc, through which a light beam passes. As particles move towards the outer edge of the disc, they pass through the light beam, attenuating the beam intensity. Detector beam attenuation is continuously recorded and converted by the operating software into the weight of particles at each size in the sample.

Avoid human error and achieve rapid, reliable measurement accuracy with CPS Instruments` automatic gradient builder. Building a density gradient by hand is not difficult, but can lead to human error. The CPS Instruments` automatic gradient builder eliminates the chance of a mistake during filling of the centrifuge, and allows a gradient to be formed in under a minute. The gradient builder can be calibrated for use with both water and many non-aqueous density gradients, depending on the liquid in which the sample is suspended.

Optimize your operational efficiency with CPS Instruments` autosampler. The autosampler carousel hooks onto the front of your disc centrifuge and holds up to 20 samples and calibration standards. Our operating software enables the autosampler to make automatic injections during unattended operation, eliminating the need for an operator to initiate each measurement.
