Koehler Instrument Company

Summary of Method

 Centrifugation provides a convenient means of determining sediment and
water (content in crude oil, fuel oils, middle distillate fuels, and biodiesel.Also used in determining the precipitationnumber,demulsibility  characteristics, trace sediments, and insolubles in used lubricating oils.



Fully automatic bench top centrifuge designed expressly for petroleum
testing (applications. Features a 41⁄2" LCD touch screen control panel. This integrated touch screen can be used to turn the heat on and off, set the duration of the test, set the RCF/RPM values and choose the type of rotor assembly and corresponding glassware to be used during the test. The Servoed motor speed mechanism allows the user (to simply set the desired speed and the instrument will attain that speed. This (mechanism calculates RPM based on the given RCF and type of Rotor selected.

The Centrifuge comes equipped with a Safety Lockout Mechanism. Upon
emergency shutdown the door is locked and cannot be unlocked until the unit comes to a complete stop, the unit is turned back on, and the stop/unlock key is pressed on the touch screen display.
