We all know that ultra-low temperature refrigerators are also known as ultra-low temperature freezers, ultra-low temperature storage boxes, and so on. As one of the commonly used equipment in laboratories, using ultra-low temperature refrigerators correctly and following the operating precautions can effectively extend their efficiency and lifespan. Therefore, let's take a look at the daily usage precautions of ultra-low temperature refrigerators:

　　1. The daily usage environment requirements for ultra-low temperature refrigerators are: above 10cm above the ground, below 2000m above sea level, indoor temperature of 5-32 ℃, and relative humidity of 80%/22 ℃.

　　2. Do not place any debris around or on the top of the ultra-low temperature refrigerator to avoid affecting heat dissipation. The ambient temperature should not exceed 30 ℃, and the corners should be stable, keeping the ground flat.

　　3. The power supply voltage of the ultra-low temperature refrigerator should be stable at 220V, and the power supply current should be at least 1A.

　　If encountering a power outage, be sure to turn off the power and battery switch in a timely manner. After the power is restored to normal, turn on the power switch first and then turn on the battery switch.

　　5. Internal spare parts must be cleaned in a timely manner. For example, the filter needs to be cleaned once a month. First, use a vacuum cleaner to clean it, then rinse it with water and let it dry before resetting. The internal condenser needs to be cleaned every two months to remove dust from the surface.

　　6. When storing and retrieving samples, do not use too much force, handle with care, try to open and close the door as quickly as possible, and use less force to lock the door to avoid damaging it.

　　The above are the daily usage precautions for ultra-low temperature refrigerators, and there are many more that won't be elaborated on here. Interested friends can follow our official website www.hsy515.cn!
