Preparing autoclave sterilization manufacturers
(1) Check that the safety accessories are complete and in good condition;
(2) Whether the body and the pressure component have cracks, deformation or leakage;
(3) Whether the various valves and sealing components are in good condition, whether there are running, running, dripping, leaking and water accumulation in the cylinder;
(4) The quick-opening type pressure vessel shall be subjected to the tightening and meshing test of the end cap and the cylinder flange;
(5) The pressure of the pressure gauge should be at zero before the equipment is steamed;
(6) Wipe the cabinet indoors cleanly, and the exhaust pipe should be unblocked;
(7) The items to be sterilized are placed in the metal blue as required, and are loosely placed so that the steam can uniformly act on the loaded items. When sterilizing the glass container, place the open glass container mouth down or flat.
The principle of high pressure steam sterilizer manufacturers
The sterilized articles are placed in a closed pressure vessel, and the water is boiled by heating to generate steam (such as a steam boiler), and the steam is introduced into the pressure vessel, and the cold air in the vessel is drained by the hot steam, and then the valve is closed. , continue to heat. Due to the rapid expansion of hot steam in a closed container (about 1700 times), the pressure inside the container increases (indoor pressure gauge pressure > 0.1 MPa), so that the temperature inside the container rises rapidly (boiling point rises), reaching above 121 °C. At high temperatures, the latent heat released by steam causes the proteins in the microorganisms to coagulate and denature to achieve sterilization.
Composition and classification of high pressure steam sterilizer manufacturers
The structure of the pressure vessel is mainly composed of a casing (body and head), a connecting member, a sealing member, a connecting pipe, a safety accessory (a safety valve and a pressure gauge), and a support.
At present, the commonly used autoclaves can be divided into two categories: one is a lower exhaust type autoclave, which has the advantages of high temperature, strong heat penetration and good sterilization effect; the other is vacuum pumping. The vacuum sterilizer belongs to the current advanced pressure vessel equipment, and has the advantages of quick discharge of cold air, short sterilization time, light damage to articles, low ambient temperature and automatic drying.
