Performance Features
1. Rapid cooling, reaching your desired temperature even faster.
2. Temperature numeric setting with high-brightness LED display.
3. Full-closed magnetic stirrer, maintaining stirring stability.
4. The diameter of the adjustable expansion cover can be adjusted according to the outer diameter of the reaction vessel used, reducing refrigerant consumption. Standardly equipped with a clear glass cover, an optional ring cover is also available.
5. Equipped with an internal secondary stirrer, working in conjunction with the stirrer inside the reaction vessel, to maintain a uniform temperature of the sample.
6. Equipped with a fixed rod, bracket, and beaker clip for easy placement and fixation of titration tubes, sensors, and other accessories (optional). The default sensor is an integrated probe, but an external probe can also be set according to customer requirements.
7. Utilizes imported compressors for high reliability and efficiency.
8. A convenient liquid outlet for staff to change the bath liquid.
