The HI900301 is a replacement overhead stirrer assembly for the HI901 and HI902C Automatic Titration Systems.
HI900301 includes the overhead stirrer and three propellers. The stirrer assembly is easily adjustable once it is placed on the HI900320 stirrer stand. With a simple adjustment of the positioning collar, the stirrer, dispensing tube, and all attached probes are able to be lowered into a sample beaker at the beginning of a titration and lifted out at the conclusion.
During titrations, the sample being tested should be stirred. The use of an overhead stirrer allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time of a sensor in achieving a stable reading, which ultimately leads to a more accurate titration result. The overhead stirrer ensures effective mixing with a selectable speed from 100 to 2500 rpm. The durable propellers included with the HI900301 can easily be removed from the stirrer shaft when cleaning or replacement is necessary.
