1. Sterilization temperature and time

high pressure steam sterilizers

The high pressure steam sterilizers manufacturer reminds you that according to the size of the capacity, the autoclave can be divided into three types: portable, vertical and horizontal, among which the vertical autoclave is more common. Because large-scale equipment is usually more expensive and has more functions, many people think that large-scale equipment must be more effective than small-scale sterilization equipment. In fact, this is a wrong perception.

As long as the volume of the high pressure steam sterilizers can accommodate the sterilized items, and the packaging and loading of the sterilized items comply with the regulations, the “temperature-time” procedure of 121°C×20min~30min, or 132°C~134°C×4min can be performed. achieve the specified sterilization effect.

2. Dryness of the steam

The high pressure steam sterilizers should use saturated steam with a drying degree of not less than 0.9, that is, the water content of the steam should not exceed 10%, and the drying degree should not be less than 0.95 under the metal load state, so as to maintain a linear relationship between temperature and pressure.

3. Packaging and placement of sterilized items

When sterilizing items, the sterilization package placed should not be too large or too tight, and enough space should be reserved to facilitate the circulation of steam and the drying of sterilized items. When sterilizing containers such as beakers and test tubes, it is necessary to place the opening downward or horizontally, otherwise the sterilization will be insufficient. Also, be careful not to allow items to block the holes and temperature sensors in the sterilizer.

4. Water quality will affect the effect and life of the sterilizer

The choice of water for the sterilizer is also important. If the water quality does not meet the requirements, it may cause problems such as scale and corrosion, which will affect the effect and service life of the sterilizer. It is recommended to use soft water or pure water. The hardness of the water is between 0.7 and 2.0 mmoL/L. The water used needs to be filtered and treated, and the sterilizer body should be kept clean.

5. The maintenance time of aseptic state is related to packaging

How long an item can remain sterile after high pressure steam sterilizers sterilization is complete is related to its packaging material. If it is a naked consumer product, it must be used immediately; if it is a fabric package, it can be stored for 7 to 14 days; the validity period of dry storage in a hard container can be up to half a year. However, if the item has a wet pack after sterilization, it is considered an invalid pack.
