PSL SystemtechnikModel CF15 -Multi-Rack Cold Finger

SHARE
The Multi-Rack Cold Finger CF15 by PSL Systemtechnik is an advanced laboratory instrument designed for detailed analysis of wax and paraffin deposits in crude oil. Featuring up to 15 measuring stations, it allows for simultaneous testing of various sample conditions, thereby enhancing the efficiency of the screening process. The instrument employs a cold finger technique, wherein a cooled portion is introduced into a stirred and heated oil sample, causing waxy components to precipitate on its surface. These precipitates can then be weighed to determine both the deposition rate and the total wax content. The system includes individual temperature control and stirring speed settings for each rack of 5 measuring places, as well as a dry bath that allows for precise temperature management up to 120°C (248°F). Modular in design, this device supports numerous customization options and can be controlled via software, enabling detailed data logging, interval measurements, and later analysis. The high precision balance provides accuracy to 0.01 g, and the integrated drawers simplify handling and removal of samples during testing. Ideal for labs focusing on crude oil analysis, this instrument supports a variety of measurement needs, including wax deposition rate assessments and the evaluation of different inhibitor concentrations.
