High-pressure Steam Sterilization

High-pressure medical lab equipment sterilization (autoclaving) to kill all microorganisms, including spores, including, sterilization is the best, the most widely used methods of sterilization. Method is to require sterilization of materials in a pressure cooker (autoclave) inside, does not spill when heated steam, vapor pressure within the autoclave temperature increases rather increased. At 103.4kPa (1.05kg/cm2) vapor pressure, the temperature reached 121.3 ℃, for 15 ~ 20 minutes. Ordinary medium suitable sterile, physiological saline, surgical instruments, containers and glass syringes, dressings and other articles.

A heat sterilization law
Is the most effective method of sterilization. In 103.4kPa (1.05kg/cm2) vapor pressure, the temperature reached 121.3 ℃, maintain 15 ~ 20min, to kill all microorganisms, including spores, including. Autoclave is made in accordance with this principle, commonly used in the general media, saline, surgical dressings and other high temperature, humidity sterilized items.
Autoclaving is restricted by several factors, such as fats and oils mixed with water can therefore not be sterilized with high pressure steam. Plastics will melt under high temperatures, many chemicals, high temperatures will be destroyed, and so on.

Furthermore, the time required for autoclaving depending on the type and volume of the article to be sterilized. Hot steam must ensure that there is sufficient time to penetrate into the article, so the larger the volume of the article, the longer the time required; article more difficult to penetrate into the steam, the longer the time required.

Note the high-pressure medical equipment sterilization law.

First, the sterile package is not too large ( less than 50cm × 30cm × 30cm), should not be too tight, there must be a gap between the parcel, so that the steam can easily penetrate into parcels central convection. Before sterilization, the vent opening of the tank or cartridge is conducive steam circulation. And the exhaust steam can be discharged quickly to keep goods dry. Sterilization is completed, close the vent tank or box to maintain sterility of items.

Second, cloth items should be placed on metal objects, otherwise cold vapor condensed into water droplets, so damp cloth. Hinder the central steam into parcels, seriously affecting the sterilization effect.

Third, the periodic inspection sterilization effect.
