Fully Automatic Drug Freezing Point Tester

YJ-0613G Fully Automatic Drug Freezing Point Tester

This instrument is designed and manufactured in accordance with the requirements of the "Freezing Point Determination Method" (General Rule 0613) in Part IV of the 2020 edition of the *Pharmacopoeia of the People's Republic of China*, used for testing the freezing point of chemical reagents and drugs. The instrument adopts a modular design, with advanced sensors in the detection part and an industrial-grade PLC system in the main control unit, ensuring stable control performance. It utilizes a high-performance compressor for refrigeration, offering advantages such as fast cooling speed and long service life. The instrument is operated via an industrial control screen. After loading the sample, a single button starts the process, featuring automatic reciprocating mechanical stirring, automatic display of temperature curves, automatic determination of the freezing point, and automatic printing of test data. The instrument is equipped with both heating and cooling functions, with a wide temperature control range for the medium bath.
