Centrifuge
Laboratory Centrifuge Description
The Oil Test Centrifuge is a heated chamber centrifuge used to determine water and sediment in oils. The large diameter chamber, with four place rotor and cushioned adaptors allows the use of 6 and 8 inch conical, pear-shaped, trace sediment and 12.5 ml tubes.
The swing out rotor ensures that samples are held near vertical when at rest allowing precise measurement of sediment. The centrifuge features a hinged lid that opens to the fully upright position to allow easy loading and unloading of tubes between tests.
Speed, temperature and timing are microprocessor controlled. Run parameters are entered via a liquid proof ‘touch panel’ and digital display.
