Multi-Place Cold Finger (1)

Multi-Place Cold Finger (1)

Manufacturer: Vinci Technologies
Model Number: MCF Series

The cold finger apparatus provides a fast and reliable method of quantifying the efficiency of wax deposition inhibitors. A hydrocarbon sample is stored in multiple cells; each having a different inhibitor. The cells are placed in an isothermal bath at a production-representative temperature. Hollow cylindrical rods, referred to as “fingers”, submerged in the samples are cooled by an internally circulating refrigerant and the finger temperature is monitored by an internal temperature probe. Wax progressively deposits itself on the fingers and the latter are removed and weighed at the end of the experiment. The relative performances of the different inhibitors can then be deduced from the deposition amounts. Furthermore, the wax can be collected and its composition analyzed. The MCF series can be configured with 6, 12 or 18 sample bottles.
