<p><span style="font-size: 16pf; color: #000000;">A&nbsp;centrifuge &nbsp;is&nbsp;usedto separate particles suspended in a liquid according to particle size and density, viscosity of the medium, and rotor speed. Within a solution, gravitational force will cause particles of higher density than the solvent to sink, and those less dense than the solvent to float to the top. We supply centrifuges with calibration certificate.</span></p>
