Low Temperature Thermostat Reaction Bath For Cooling / Heating / Constant Temperature And Other Experiments Of Flask / Test Tube Product Description Low Temperature Thermostat Stirring Reaction Bath Product Pverview It can replace dry ice and liquid nitrogen for low-temperature reaction with high temperature control accuracy. It is mainly used for cooling, heating and constant temperature of flask, beaker and test tube. It is used for the experiment, detection and identification of biological enzymes in hospitals, scientific research and universities. The machine adopts LCD control system with temperature programming and program control functions, which is suitable for both single point constant temperature control and continuous variable temperature control; The compressor, expansion valve, solenoid valve and other key components of the refrigeration system are imported famous brand products to ensure the safe and efficient operation of the system and reduce noise; The system is equipped with air-cooled condenser and water-cooled condenser (optional), which can be suitable for different applications and improve refrigeration efficiency. For example, biopharmaceutical, chemical and food engineering need high-precision constant temperature experimental field source. Product Features 1. LCD controller is used for temperature digital setting and display. 2. fully enclosed magnetic stirrer to ensure mixing stability. 3. it can be equipped with built-in two-stage stirring to keep the temperature of the sample uniform together with the stirrer in the reaction vessel. 4. it is equipped with a fixed rod to facilitate the placement and fixation of burette, sensor and other supporting devices. 5. compressor of international famous brand, with high reliability and efficiency. 6. there is a drain port for staff to change bath liquid. 7. stainless steel materials shall be used for parts that may contact with the working medium such as tank, top plate, electric heater and evaporator. protection device: with self diagnosis function; Refrigerator overload protection; High voltage pressure switch, overload relay, thermal protection device and other safety protection functions. 8. the refrigeration system has a variety of protection devices such as time delay, overheating and overcurrent. They are imported original high-quality devices to ensure reliability and service life. 9. p.i.d control, try to eliminate external factors affecting temperature regulation accuracy and reduce error.
