Callisto 100 comes ‘ready to go’ and contains all required components for operation in accordance with the standard methods. Testing and results are in full compliance with ASTM D6371, EN 116, EN 16329, IP 309 and JIS K2288. In addition, Callisto 100 can be used for manual cloud and pour point measurements.

Innovative temperature control

Based on Anton Paar’s 30 years plus experience in Peltier element temperature control technology. Callisto 100 comes with a newly developed state-of-the-art Peltier element concept which allows the connection of an inexpensive methanol-free cooling system. Just a small chiller system with antifreeze that has a cooling capacity at -20°C of 220 Watt is sufficient. With this cooling device Callisto 100 can measure samples with a CFPP value below -35°C.

As well as enhancing laboratory safety by removing methanol based systems, it also ensures outstanding homogeneity of the cooling jacket, which is the most critical and decisive parameter for a correct CFPP value determination.

State of the art user interface

For easy and intuitive operation, Callisto 100 comes with pre-programmed standard test methods and the ability to create and store up to 90 individual user programs. The large colour display indicates the
sample and jacket temperatures in real time. It also provides additional graphical information about the aspiration and back flow times allowing the operator to observe the temperature behaviour of the sample during the test.

Thanks to the contact-free infrared detection technology, the complete filtration unit is easily accessible and has the same detection position in each test, which ensures high accuracy and repeatability. Callisto 100 delivers excellent detection, even when the pipette is frosted, and daylight cannot cause interference with the measurement.

High sample throughput

Callisto 100 offers high sample throughput. There is a storage place at the rear of the instrument to hold a second complete filtration unit. Once this is prepared, the instrument is ready for the next test run within seconds.

To make the cleaning of the pipette as easy as possible, a programmable automated cleaning routine can be initiated at the push of a button. In addition, Callisto 100 is entirely maintenance-free.

Why is it important to measure Cold Filter Plugging Point?

All diesel fuels contain wax and when the temperature of the fuel decreases, wax crystals will begin to precipitate. If enough wax precipitates, these crystals can block the fuel flow through screens, filters and other restricted passages in the fuel system.

The tendency of a fuel to plug screens and filters at low temperature is a dynamic property dependent on the size and shape of the wax crystals. It affects engine & vehicle design and the fuel system configuration. To evaluate the plugging tendency of diesel fuel, dynamic test methods for low temperature operability have been developed as European standard methods and these are known as the Cold Filter Plugging Point (CFPP) methods.

By definition the CFPP value is the highest temperature at which a given volume of fuel fails to pass through a standardised filtration device in a specified time when cooled under standardised conditions. This test gives an estimate for the lowest temperature at which a fuel should give trouble-free flow and helps refineries to optimise their production process when producing different diesel products (e.g. summer diesel and winter diesel).
