The electric constant temperature drying oven is a commonly used equipment in the laboratory, which is used for heating, drying, baking samples and other operations. Proper usage and precautions are essential to ensure the accuracy and safety of experimental results. The following are the things you need to pay attention to when using an electric constant temperature drying oven and how to use it correctly.
How to use:
1.Preparation, before using the electrically heated thermostatic drying oven, make sure it is clean and remove any impurities or residues from the drying oven. Check that the power connection of the drying oven is secure, and make sure that all control buttons and displays are working properly.
2.Set the temperature, set the temperature of the drying oven according to the needs of the experiment. Open the oven control panel and set the desired temperature via the control button or touch screen. Note that the temperature setting should be adjusted according to the nature of the sample and the experimental requirements.
3.Preheating, which is performed before placing the sample. Preheat for a period of time according to the set temperature, usually the recommended preheating time is 1530 minutes, to ensure that the internal temperature of the drying oven is stable to the set temperature.
4.Place the sample and place the sample to be processed on a sample rack inside the drying oven or on a dedicated sample tray. Be careful not to place the sample directly at the bottom of the drying oven so as not to affect the air convection and heating effect.
5.Operate the drying oven, start the heating function of the drying oven, and choose whether to start the fan function or not as needed. The fan function accelerates air convection for a more uniform drying effect. During the drying process, the temperature and the status of the experimental sample can be monitored at any time.
6.At the end of the operation, after the experiment, first turn off the heating function and fan function of the drying oven. Wait for the internal temperature of the drying oven to drop to a safe temperature before opening the drying oven door and removing the sample.
7.Cleaning and maintenance, after use, clean and disinfect the inside of the drying oven in time to ensure that it is clean and hygienic for the next use. Regularly inspect the power cord and connections of the drying oven for damage to ensure safe use.
Precautions
1.Safe operation, when operating the electric heating constant temperature drying oven, be sure to follow the safety operation procedures. Avoid touching hot surfaces and hot air to avoid burns.
2.Avoid overloading and do not overcrowd the inside of the drying oven, so as not to affect the air convection and heating effect. Make sure there is enough clearance between samples to allow air circulation.
3.To prevent sample leakage, it is important to use an airtight container for samples that may produce gases or liquids, and ensure that the container is well sealed to avoid contamination or damage to the inside of the drying oven.
4.Avoid overheating and do not set the drying oven beyond its maximum temperature range to avoid damaging the equipment or causing safety accidents such as fires.
5.Clean in time, clean the inside and outside of the drying oven regularly to ensure that the equipment is in good working condition. Replace damaged or aging parts in a timely manner to prolong the service life of the equipment.
By following the correct usage methods and precautions, the safe operation and effective use of the electrothermal thermostatic drying oven can be ensured, while protecting the safety of the experimenter and the integrity of the experimental samples.
