Koehler Instrument Company, Inc. (USA) is pleased to introduce their redesigned heated oil test centrifuge. Koehler’s latest model centrifuge incorporates the accuracy and precision of their previous model with enhanced features such as a user friendly LCD Touch Screen Control Panel. The control panel not only controls the speed at which the centrifuge rotates but can also be used to turn the heat on and off, set the duration of the test and choose the type of rotor assembly and corresponding glassware to be used during the test. A choice of Long, Short, Pear and Finger tube rotor assemblies and glassware are available to meet laboratory requirements.
Additional improvements from the previous model include a motor speed mechanism that calculates an RPM value based on the User defined parameters for RCF setting and type of rotor selected. The centrifuge features a large, top opening lid providing easy access to the rotor and tube holders and for cleaning of the unit. The lid has an 18 ½” diameter viewing window allowing the operator to monitor the samples throughout the test run. Ensuring safety while providing the latest equipment to the petrochemical industry is Koehler’s goal and to this end they have incorporated various features. The centrifuge is equipped with a safety lockout mechanism, a nitrogen purge feature, and has been manufactured to meet the Class 1, Division 2 explosion resistant rating.The new heated oil test centrifuge conforms to a broad range of Standard Test Methods including ASTM D91, D96, D893, D1796, D2273, D2709, D2711, D4007; IP 75, IP145, IP 359; API 2542, API 2548; ISO 3734; DIN 51793; NF M 07-020. For biofuels applications, the centrifuge also meets ASTM D2709 requirements for Water and Sediment for B100 Biodiesel and B6 to B20 Diesel Fuel Oil, Biodiesel Blends.
