Techbox Systems cold finger apparatus enables fast and efficient screening of wax inhibitors. CF1 is a low cost, basic, single cell system. To reduce costs the standard unit can be supplied without a water bath, hotplate stirrer or beaker which many laboratories already have.

The unit operates using a “cold finger” submerged in warm test oil. If the cold finger is below the wax appearance temperature of the sample the wax will come out of solution and stick to the cooled surface. This wax can then be quantified by weighing and further analysis performed on the sample if required.
