Description

The automated PCT 1300 instrument reveals the brine crystallization temperature in a high-pressure, low-temperature environment. The apparatus encompasses highly sensitive fiber optic transmission probes that enable crystal detection in the brine sample. These eliminate the arduous and erroneous manual surveillance of crystallization events, e.g. FCTA, TCT and LCTD. The apparatus comprises a high-pressure test cell, in which a magnetically driven stirrer ensures a thorough sample agitation and homogenization. Moreover, an internal sensor continuously reports the sample temperature. A double jacket with an integrated refrigerant circulation system is wrapped around the cell to provide and maintain sub-ambient temperatures. Fluid pressurization is attained by virtue of a high-pressure syringe pump.
