CFPP and CPPP

AirSTAR, the 3-in-1 platform for Cold Property testing

AirSTAR ColdBlock

Cold Filter Plugging Point (CFPP) and Cloud Point Pour Point (CPPP) / Cloud Point (CP)

Integrated cooling unit for CFPP Head and CPPP Head, ColdBlock is AirSTAR’s cooling system. No external chiller is required, even when cooling down to -105˚C. Operation is easy with the built-in iPad and in-house developed iLabCB app. Along with easy navigation the app includes:

• Pre-installed and customizable methods
• Unique insight in test behaviour:
• Vacuum profile per every single CFPP aspiration
• Anomalous aspiration highlight
• “Not empty before next” highlight (CFPP-2)
• Camera images of Cloud & Pour Point test intervals are saved in test result.

Data handling options include export to LIMS / Windows PC and print PDF / kiosk printer. And with the 16Gb iPad, results storage is practically unlimited.

The ColdBlock can do both stepped cooling profiles (traditional) and Linear cooling profiles – for instance for the EN16329 CFPP method where it cools down with 30˚C/h.

Custom cooling profiles can be created in almost any form. From a simple “1-step at -90˚C” to complex multi-step profiles with heating, cooling and even linear steps all in one profile.

AirSTAR CFPP Head

Cold Filter Plugging Point Head, all the aspects and parts required for Cold Filter Plugging Point testing are housed inside the CFPP Head. The small yet advanced vacuum system measures and controls the (negative) pressure in real-time throughout every individual sample aspiration.

Sample detection

Small laser lights – one in the bottom and two in the top of the pipette – ensure accurate detection of the sample. The pipette-lock ensures that the pipette sits securely within the detection zone, and the smart self-adjusting algorithm is perfectly able to deal with condensation in the bottom.

Cleaning is most easy using AirSTAR’s Cleaning-Docking station. After the test, dispose the sample and remove the filter. Then simply put the CFPP Head in the Cleaning-Docking station and push the little button on top of the Head. After the cleaning cycles are finished, remove the cleaning beaker and start the drying cycle by pushing the button again.

AirSTAR CPPP Head

Cloud Point Head Pour Point Head. All the aspects and parts required for Cloud & Pour Point testing are housed inside the hand-held CPPP Head. An advanced camera looks down from the top into the jar. Because it sees through the entire sample (Cloud Point) and looks at the entire sample surface (Pour Point), the detection is not limited to only a single spot in the sample.

AirSTAR’s CPPP camera mimics the human eye observation in the manual methods ASTM D2500 (Cloud Point) and ASTM D97 (Pour Point).

Lifting and tilting of the jar

The CPPP Head lifts the jar out from the bath at every test interval (both with Cloud and Pour Point). With the Pour Point it also tilts the jar when it is in its top position. These motions mimic the procedures of the manual methods ASTM D2500 and D97.
