To select a suitable vertical high-pressure sterilizer for a cell culture laboratory, comprehensive consideration should be given to sterilization requirements, equipment performance, and laboratory conditions. Specific recommendations for selection are as follows:

1、 Clarify sterilization requirements

Types of sterilized items: Items that need to be sterilized in cell culture laboratories include culture media, serum, glassware, plastic consumables, etc. Different items have different requirements for sterilization temperature, time, and steam penetration. For example, liquid culture media should avoid component damage caused by high-temperature boiling, and equipment with a "liquid sterilization" mode should be selected; Glassware should ensure sufficient steam penetration to avoid incomplete sterilization.

Sterilization volume and frequency: Determine the sterilizer volume based on the laboratory scale. Small laboratories (such as cell culture rooms) can choose 30-50L equipment to meet the daily sterilization needs of containers; Large laboratories (such as stem cell culture centers) need to choose equipment with a capacity of over 100L to cope with high-frequency and large-scale sterilization tasks.

2、 Pay attention to the core performance of the device

Temperature and pressure control accuracy: Cell culture requires high sterile conditions, and sterilizers need to have high-precision temperature control systems (error ≤± 1 ℃) to ensure stable sterilization temperatures of 121 ℃ or 126 ℃; The pressure control should be precise to 0.01 MPa to avoid sterilization failure caused by pressure fluctuations.

Exhaust and drying function: Choose equipment equipped with "micro exhaust" or "slow exhaust" function to prevent liquid items from boiling and splashing due to rapid exhaust; The drying function can shorten the cooling time after sterilization and improve work efficiency.

Safety protection design: Priority should be given to equipment with self sensing pressure interlock devices. When there is pressure in the chamber, the chamber cover cannot be opened to prevent accidental operation that may cause steam to spray out and injure people.

3、 Match laboratory conditions

Space and power requirements: The vertical high-pressure sterilizer should be placed on a stable and ventilated ground, avoiding direct sunlight or humid environments. Confirm that the laboratory power supply voltage (AC 220V ± 22V, 50Hz ± 1Hz) matches the equipment to avoid unstable voltage affecting equipment operation.

Convenient operation: Choose devices with LCD display interface and one click operation program to reduce the difficulty of operation; Equipped with automatic drainage function to reduce manual maintenance costs.
