Low temperature water reaction bath introduction
Low temperature reaction bath is a new type of experimental instrument which is improved and manufactured by our company. It is suitable for low temperature experiments in scientific research, biology, physics, medicine, chemical industry and other departments. It can replace dry ice and liquid nitrogen for low temperature reaction and provide low temperature conditions for related equipment. It can also be used as a low temperature reaction bath for viscosity measurement. , It is divided into two stages of constant temperature stirring, so that the temperature in the stainless steel tank is more uniform, and the intelligent temperature control is accurate.
Low temperature reaction bath structure
The main components of the low temperature water bath are the compressor, the reaction bath, the magnetic stirrer and the liquid crystal display.
Compressor
Balanced design makes the compressor less vibration, low noise and smooth operation
Reaction bath
Stainless steel inner tank, chrome-plated surface of coil evaporator, corrosion-resistant
How Low Temperature Reaction Bath Works?
The low temperature water bath controls the temperature of the circulating water through the thermal cycle controller to achieve the purpose of low temperature and constant temperature. If the set temperature is higher (or lower), the entire tank should be kept warm to reduce the heat transfer speed and improve the constant temperature accuracy. The stirrer is driven by a small electric motor, and the stirring speed is adjusted by a transmission or a transformer. Commonly used relays in laboratories are tube relays and transistor relays. To measure the quality of the constant temperature water bath, the sensitivity of the water bath is the standard. If the required temperature is not much different from the room temperature, a 20m³ round glass cylinder can be used as a container. Electric heaters have small heat capacity, good thermal conductivity and appropriate power. When the room temperature is too low, a larger power or two sets of heaters should be used. The relay is connected with the heater and the contact thermometer to control the temperature.
Low temperature water reaction bath advantages and features
(1) The bottom of the low temperature tank is equipped with magnetic stirring, and the stirring speed is adjustable. (optional)
(2) The fully enclosed compressor unit is used for refrigeration, and the refrigeration system has multiple protection devices for overheating and overcurrent.
(3) The circulating pump can draw out the constant temperature liquid in the tank to establish a second constant temperature field.
(4) The cooling liquid in the low temperature cooling bath can be introduced to the outside, the experimental container outside the cooling machine can be cooled, and the low temperature and constant temperature experiments can also be carried out directly in the tank.
test.
(5) XMT analog and digital PID automatic control system is adopted, and temperature is digitally displayed.
(6) The inner tank is made of 304 stainless steel, which is clean, hygienic, beautiful and corrosion-resistant.
(7) The drum-type liner is used, and the stirring is more uniform without dead ends. The design without coils inside the tank can be used to fully utilize
Use the experimental space inside the tank.
(8) Equipped with a lower liquid outlet to facilitate the replacement of media.
(9) The bottom is equipped with high-strength casters, which is more convenient to move.
