Natural convection oven is a constant temperature equipment widely used in laboratories. Its working principle is to circulate hot air through natural convection to achieve constant temperature drying of items.
Selection points
1. Temperature range: The temperature range of the natural convection oven is generally from room temperature to 300°C, and an appropriate temperature range needs to be selected according to the experimental needs.
2. Volume size: The volume size is generally 20L to 500L. Select the appropriate volume size according to the experimental requirements to avoid waste caused by too small or too large volume or the experiment cannot be carried out.
3. Temperature uniformity: The internal temperature uniformity of the natural convection oven is of great importance to the experimental results. It is necessary to select equipment with uniform temperature distribution and stable temperature adjustment.
4. Temperature control: Natural convection ovens need to have precise temperature control functions to ensure that the temperature is stable during the experiment.
5. Material: The internal and external materials of the natural convection oven should be made of high temperature resistant and corrosion resistant materials, such as stainless steel.
Precautions
1. Before use, you need to check whether the equipment is in good condition, and confirm whether the temperature controller, power supply, wires, etc. are normal.
2. When using, it is necessary to operate in accordance with the instructions to avoid equipment damage or experimental failure caused by excessive use or improper operation.
3. Avoid overloading during use to avoid damage or danger to the equipment.
4. During use, it is necessary to avoid putting flammable, explosive, volatile and other substances into the natural convection oven to avoid danger.
5. Regularly clean the interior of the natural convection oven to avoid the accumulation of dust and debris that will affect the quality of the experiment.
6. After use, it is necessary to wait for the equipment to cool down before taking out reagent bottles and other items to avoid burns.
7. Periodic calibration of temperature controllers is required to ensure accurate temperature measurements.
8. When drying items in the equipment, reagent bottles, petri dishes, etc. need to be placed evenly to ensure uniform drying effect.
