The Advanced 4C3 multi-sample cryoscope uses the preferred freezing-point method to precisely determine the amount of extraneous water in milk, offering unique continuous throughput for maximum efficiency in large volume testing. The capacity of the 4C3 allows your lab to efficiently test and manage supplied milk in order to properly compensate producers, ensure quality products and profitable returns. The 4C3 is microprocessor controlled for simple, pushbutton operation. Extensive self-diagnostic and troubleshooting prompts keep you up and running.
Batch testing is also efficient with the 4C3; samples can be prepared in advance and loaded into sample cassettes. When ready to begin testing, an operator can load up to four sample cassettes (holding up to 40 samples) into the cryoscope, press Start and walk away. The instrument automatically tests each sample in turn and records the results; keeping your cryoscope and operator working at peak efficiency.
The Advanced 4C3 freezing-point technology complies with both the International reference and screening method, delivering precise, accurate, repeatable and reliable results. With the unique dual-stage, solid-state cooling assembly, testing can begin immediately without waiting for the instrument to cool down.
Calibration is simple, the calibration samples are loaded into the specially coded calibration cassette and calibration is automatically triggered to run unattended. The 4C3 also offers an optional barcode scanner to automate positive sample identification and eliminate test result transcription errors.
