Product overview
Centrifuge executes centrifugal phase separation of petroleum samples per ASTM D4007 protocols.
The Oil Test Centrifuge is a heated chamber centrifuge used to determine water and sediment in oils. The large diameter chamber, with a 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.
