Refrigeration method and use of refrigeration water bath oscillator

Refrigerated water bath oscillator

1. Overview
The digital display chilled water bath constant temperature oscillator is widely used in medical, petrochemical, sanitation and epidemic prevention, environmental monitoring, soil analysis and other scientific research departments for biological, biochemical, cell, bacterial and other fluid and solid compounds. .This machine has the characteristics of reasonable structure, simple operation, high stability and performance. It adopts imported compressor for refrigeration, has the advantages of low noise and rapid refrigeration. It is an ideal equipment for experimenters.

3. How to use
First of all, please remove the stainless steel cover of the oscillator and add water to the water tank. The amount of water added is controlled according to the needs of the experiment, but at least the water level should be higher than the heating tube to prevent the heating tube from burning out. Generally, it is better to add 2/3 of the water tank. , The water will overflow during shaking and affect the experiment. Then put the sample to be shaken in a beaker or flask on the spring clamp, turn on the power, turn on the power switch, turn on the timer to normally closed "ON" or you need When the time is set, the indicator light is on, indicating that the power supply in the machine has been turned on, and the oscillation frequency is controlled by the speed control knob, which is adjusted from low speed to high speed from left to right.
Set temperature: press the SET key to set or view the temperature set point, press the SET key once and the digital tube character starts to flash, indicating that the instrument enters the setting state, press the Δ key to increase the setting value, and press the ▽ key to decrease the setting value Small, long press the Δ key or the ▽ key, the data will change quickly, and the SET key will return to the normal working state and the temperature setting is complete. When the set temperature is lower than the ambient temperature, please turn on the cooling switch.

Four, matters needing attention
1 The case of the instrument should be properly grounded to avoid accidents.
2 It is strictly forbidden for various liquids to enter the machine to avoid damage to the host.
3 When not in use, the power should be cut off, and the dry water tank should be placed in a ventilated and dry place.
