Request InfoTesta Analytical Solutions eKThe BI-XDC X-Ray Disc Centrifuge from Testa Analytical Solutions EK enables scientists to make accurate, high-resolution particle size distribution measurements, from nm to tens of μm, without the need for time-consuming calibration or absorption correction. Based on the principle of photosedimentation, the BI-XDC measures the size of particles according to the time the particle takes to sediment in the detector according to Stokes law. Combining centrifugal and gravitational sedimentation in a single instrument, the BI-XDC features a reproducible digitally controlled disk speed to...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra June 2023 IssueRatio PyrometersThe CSvision series of ratio pyrometers from Optris Infrared Sensing LLC measures the temperature of metals, melts, or ceramics in a safe, noncontact fashion from different distances.
