Electrothermal Thermostatic Water Bath
Equipment Introduction
The electrothermal thermostatic water bath circulator is a versatile piece of equipment commonly employed for evaporation and thermostatic heating in laboratory settings. Its design typically features a tank-type structure, which is divided into two distinct layers. The inner layer is constructed from high-quality materials such as aluminum or stainless steel plates, ensuring durability and resistance to corrosion.
At the base of the water bath, an electric heating element is strategically positioned, supported by a robust bracket. This configuration not only facilitates efficient heat distribution but also enhances the stability and longevity of the heating element. The integration of these components within the water bath underscores its robust design and functionality, making it an indispensable tool for various laboratory applications.
Precautions for Use
When operating an electrothermal thermostatic water bath, several critical safety measures must be adhered to. Firstly, maintaining the correct water level is paramount. The water level should never drop below the electric heater, as this can lead to overheating and potential damage to the heating element. Conversely, the water level should not exceed two-thirds of the water bath's capacity to avoid overflow, which could lead to water spills and subsequent electrical hazards.
Additionally, dampness in the control box should be strictly avoided. Moisture can cause electrical leakage, posing a risk to both the controller and the operator. Regular inspections should be conducted to ensure the control box remains dry and free from any signs of dampness.
Lastly, monitoring for leaks is essential during operation. Any leakage from the water tank could indicate a more significant issue that needs immediate attention. Regular checks should be performed to ensure the integrity of the water tank and to prevent any potential accidents.
By following these precautions, the risk of equipment damage and safety hazards can be significantly reduced, ensuring a safer laboratory environment.
Electrothermal Constant Temperature Oil Bath
Equipment Introduction
The constant temperature oil bath is a versatile piece of equipment in the laboratory, sharing a similar construction to the electrothermal thermostatic water bath but with a crucial difference: the heating medium is oil rather than water. This modification allows for higher temperature capabilities, making the oil bath an essential tool for high-temperature thermostatic processes.
The oil bath operates by using high temperature tube furnace heating tubes to heat the thermal oil. This oil, once heated, is circulated through the system to maintain a consistent temperature. The precision temperature control instrument plays a pivotal role in this process, ensuring that the temperature remains accurate and stable throughout the experiment.
Key features of the constant temperature oil bath include its ability to handle higher temperatures compared to water baths, making it suitable for a broader range of applications. The use of oil as a heating medium also provides better thermal stability and uniformity, which are critical for precise experimental outcomes.
In summary, the constant temperature oil bath is an indispensable high-temperature thermostatic equipment in the laboratory, offering enhanced capabilities and precision over traditional water baths.
Precautions for Use
When injecting liquid into the oil bath, it is crucial to monitor the liquid level to prevent any potential overflows. Specifically, when the experimental temperature reaches 300℃, the liquid level should be maintained at approximately 80% of the total volume to ensure safe operation. It is strictly prohibited to use flammable or volatile oils. The choice of oil should be based on the temperature and specific experimental requirements. For instance, glycerin is recommended for low-temperature applications, while cottonseed oil is suitable for high-temperature experiments.
Operating the oil bath in areas with poor ventilation or limited air exchange is ill-advised. Additionally, it should be kept away from fire sources and locations prone to producing electric sparks to mitigate the risk of fire. It is also imperative to avoid running the oil bath without any oil, as this can lead to electric leakage, fire hazards, and damage to the heating elements.
Handling the equipment with wet hands in a moist environment is prohibited due to the heightened risk of electric leakage and shock. Lastly, ensuring that the power supply uses a grounded plug is essential for safety.
