RAT-2 – Ultimate precision and safety for your digestion applications
JP Selecta's RAT-2 temperature and time control unit is an essential device for laboratories requiring precise and reproducible control of thermal digestion. Designed to meet the needs of applications such as the Kjeldahl method for nitrogen determination, COD analysis and fat hydrolysis, this device guarantees stable, safe and fully programmable performance.
The RAT-2 is mainly used in combination with the Bloc-Digest series of digestion blocks. Thanks to its intuitive digital interface, it allows the user to program up to 20 heating profiles, each with up to 4 temperature ramp or hold stages. This fine control of the process is essential in analytical procedures where time and temperature accuracy directly influence the reliability of the results. The system also allows you to control critical phases such as water evaporation, gradual temperature increase or prolonged maintenance at high temperatures without the risk of overheating.
Equipped with two type K thermocouple probes, the RAT-2 accurately measures the temperature inside the digestion block. One of the probes is connected to the main block, while the other is placed in a sample tube, ensuring differentiated monitoring between the actual heating temperature and that of the reaction medium. In the event of overheating, a safety system automatically cuts off the power supply, protecting the samples, the device and the user. The metal housing is designed to withstand the demanding conditions of analytical laboratories.
The RAT-2 is powered by an intelligent microprocessor that regulates the heating intensity via an integrated variator, ensuring a gradual and perfectly controlled temperature rise. The steps can be viewed on the integrated LCD screen, which also displays the current temperatures, programmed values and remaining times. Once the cycles are complete, an audible signal alerts the operator. This fully automated system frees up time for the user while ensuring maximum standardisation of digestion methods.
The RAT-2 control unit is a strategic choice for laboratories that demand precision, safety and efficiency. It offers a complete and reliable solution for controlling all critical heating stages in digestion methods, ensuring process traceability and reproducible results while minimising manual handling.
