Koehler Instrument K19404 / K19494 Dropping Point Tester

Product Description
Dropping point determinations are used for identification and quality control purposes, and can be an indication of the highest temperature of utility for some applications. The sample is heated at a prescribed rate in a precision machined cup whose sides slope toward an opening at its center. The temperature at which a liquid drop first falls from the cup is the dropping point of the sample.

The K19490 Dropping Point Apparatus performs dropping point determinations on lubricating greases at temperatures of up to 550°F (288°C). Tester consists of dropping point cup, test cell with accessories and oil bath with stirrer and heater. Test cell is immersed in a 400mL Pyrex bath for heating at the prescribed rate. A 750W variable step-less control heater and 1/40hp stirrer permit accurate, uniform control of bath temperature rate of rise. Heater assembly includes refractory top plate and reference dial.

Maximum Temperature: 550°F (288°C)

Bath Medium: A high temperature heat transfer fluid having a flash point in excess of 400°C is recommended. Silicone fluid is suitable.
