Main features　　

The CYWB series high-throughput intelligent microwave digestion instrument adopts microwave non pulse continuous automatic frequency conversion control, which extends the service life of the instrument and the uniformity of electromagnetic waves. The chamber adopts a large volume of 52L，The stainless steel chamber material is specially designed with a self-locking buffer explosion-proof furnace door. When the reaction is abnormal, the buffer structure ensures the personal safety of the operator and the integrity of the furnace door structure. The furnace door and chamber are tightly combined, and microwave leakage meets national standards. The instrument adopts a temperature and pressure dual control system to control the pressure and temperature of the synthesis experiment, with real-time display360 ° continuous rotation, uniform microwave, ensuring the same microwave environment for each sample and improving the consistency of experimental results.

Definition of Terms

Microwave digestion technology: a wet digestion method that utilizes the penetration and activation reaction ability of microwaves to heat the digestion solution (various acids, some alkaline solutions, and salts) and samples in a closed container, and rapidly dissolve various samples under high temperature and pressure conditions.

Dissolving tank: A sealed container 1 used for microwave digestion experiments.

Stable state: The state in which the temperature change at any point in the working space of the microwave digestion instrument reaches the performance requirements of the equipment itself.

Temperature deviation: Under the stable state of the microwave digestion instrument, the deviation between the measured temperature and the set temperature at each measuring point in the digestion tank within the specified time, including temperature upper deviation and temperature lower deviation.

Temperature uniformity: The maximum temperature difference between any two digestion tanks at a certain moment in the stable state of a microwave digestion instrument.

Packaging must be inspected: professional testing instrument calibration

Calibration of testing instruments that are commonly used in laboratories and production lines helps companies continuously control packaging quality during the research and development and mass production stages. Calibration of testing instruments in the medical industry, with data traceability function, meets the strict requirements of GMP standards for packaging integrity.
