The Seta Oil Test Centrifuge is a heated chamber centrifuge used to determine water and sediment in oils. The large diameter chamber, with six 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.
Precise heating for accurate results
Isothermal heaters fitted internally to the centrifuge chamber give precise temperature control to within +/-1 °C.
Fast and easy operation
9 programme memories allow a user to configure the instrument to automatically operate to the specified test parameters, saving time, easing operation and assisting repeatability. A ‘Quick Run’ mode allows short runs of up to 99 seconds.
A motor driven lid latch with a safety interlock prevents the centrifuge operation while the lid is unlocked. Imbalance detection and over-temperature protections protects the motor and chamber from damage.
Setafuge Hazard Reduction System
The optional Setafuge Hazard Reduction System (90010-0) can be fitted into the centrifuge to extract vapours from the chamber and significantly reduce vapour hazards.
