Matters needing attention when using constant temperature oil bath

When using a constant temperature oil bath, you must first add oil to the pot, and then turn on the power. The digital temperature controller displays the actual measured temperature, adjust the knob switch, and observe the reading to the required set temperature value. When the set temperature value exceeds the oil temperature When the heating indicator light is on, it indicates that the heater has started to work. When the oil temperature reaches the temperature you need, the constant temperature indicator light is on and the heating indicator light is off. It should be noted that the oil in the pot cannot use the electric heating tube to expose the oil surface to avoid burning the electric heating tube , Resulting in leakage phenomenon.
  
  The use of constant temperature oil bath
  
  The constant temperature oil bath is widely used for distilling, drying, concentrating and impregnating chemicals or biological products. It is an ideal and necessary tool for laboratory laboratory technicians of various universities, environmental protection, scientific research, health, epidemic prevention, petroleum, metallurgy, chemical, medical and other units!
  
  Operation rules for constant temperature oil bath
  
  1. Please read the instruction carefully before using the constant temperature oil bath
  
  2, to ensure safety, please connect the ground wire when using the constant temperature oil bath.
  
  3. The oil level should not be too high to prevent overflow and cause experiment errors
  
  4. In order to prolong the service life of the constant temperature oil bath, please be careful not to get moisture inside the control box to prevent leakage.
  
  5. The constant temperature oil bath is guaranteed for more than one and a half years since the day of delivery (man-made or improper use will be charged for the cost), and lifetime maintenance.
  
  6. After use, please pour out the oil, wipe it clean with a dry cloth, and place it in a ventilated and dry place.
  
First of all, before using the constant temperature oil bath, the management and operation staff please read the instructions in detail. When injecting liquid into the oil bath, control the liquid level to prevent excessive overflow. In summer, there is a big difference between indoor and outdoor temperatures, when the experimental temperature reaches 300 degrees. When the liquid level is controlled at about 80% of the volume, if the liquid level is not controlled, there will be fire, short circuit, and electric shock hazards when encountering high temperature and overflow.
  
Second attention: it is forbidden to use flammable and highly volatile oil. The oil used should be determined according to temperature and experimental requirements. Use glycerin for low temperature and cottonseed oil for high temperature. Generally, the oils used for constant temperature oil bath are: oil NO.1, oil NO.2, olive oil, cottonseed oil, paraffin oil, sesame oil, motor oil, The flash points of transformer oil, olive oil, cottonseed oil, and sesame oil in these oils are all around 300 degrees. Therefore, if high temperature tests are required, these oils are recommended. Otherwise, when the ignition point of the oil is reached, it will be very dangerous.
  
In addition, do not use the oil bath in places with poor ventilation, keep it away from fire sources and places prone to sparks to avoid the danger of fire.
  
Finally, it is forbidden to burn in the air without oil. It will cause leakage, fire, and burn out the heating tube. It is forbidden to operate with wet hands. There is a risk of leakage and electric shock. The power supply must use a grounded plug. It is strictly forbidden to share with the lighting line, and beware of fire due to overload of electricity. Avoid doing dangerous experiments in the laboratory alone.
