Experimental ovens are usually used in scientific research, teaching, industrial production and other fields, and are often used in operations such as material heating and drying, dehydration, sterilization, and baking. Selecting a suitable laboratory oven requires consideration of the following points and considerations:
Selection points
Temperature range: Choose an appropriate temperature range according to the needs of the experiment. Usually, the temperature range of the experimental oven is between room temperature and 300°C, and some high-end products can reach above 500°C.
Temperature control accuracy: Temperature control accuracy determines the accuracy and repeatability of experimental results. More precise experiments usually require a control accuracy of about 0.1°C.
Heating methods: Common heating methods include electric heating tubes, far infrared rays, microwaves, etc. The price of the oven heated by the electric heating tube is relatively low, but the heating is uneven; the far-infrared ray heats evenly, but the price is high; the microwave heating speed is fast, but it requires a special container.
Volume size: Choose the appropriate volume size according to the experimental needs, generally ranging from tens of liters to hundreds of liters.
Control mode: digital control or analog control can be selected. Digital control is more accurate and easy to operate, but the price is relatively higher.
Safety: The safety performance of the oven should be considered, such as overheat protection, circuit short circuit protection and other functions to ensure the safety of experimenters.
Precautions
Before use, read the instructions carefully and understand the safe operation procedures.
The inside of the oven should be cleaned regularly to avoid interference of residues to the experiment.
Pay attention to temperature control when heating to avoid overheating and overheating.
For experiments containing flammable and explosive substances, an oven with corresponding protective measures should be selected.
The service life of the oven is generally about 5 years, and it needs to be repaired or replaced when it expires.
