The Application Scope of Pulse Vacuum Steam Sterilizer
Pulse vacuum sterilizers can be widely used in personnel biological product engineering, laboratories, research institutions, etc., to sterilize and dry sterile instruments, rubber plugs, aluminum caps, culture media, glassware, waste, and other items.
Sterilization Principle
The equipment adopts its vacuum system (nonliquid program) to forcibly extract the air in the sterilization room and then introduces saturated pure steam to maintain a certain time and temperature (pressure). When saturated pure steam comes into contact with the sterilized material, the principle of heat dissipation is used to cause protein denaturation and death of bacterial microorganisms, thereby achieving the effect of sterilization and disinfection.
After the sterilization process is completed, the steam in the sterilization chamber is discharged again (nonliquid program), and the vacuum system is activated to vacuum the inner chamber, extracting the steam and water in the sterilized items, thereby achieving the drying effect of the sterilized items.
Design Principles
The product strictly follows the above standards and specifications for design, manufacturing, testing, and acceptance. The entire sterilization process is monitored online for temperature and pressure, and printed in real time. The entire process can be traced.

Box Characteristics
- Good structural design originates from good design methods, using finite element analysis to simulate and simulate the pressure, stress, and fluid dynamics during the operation of the sterilizer during the design process.
- Sterilizer:
Material: The main body is made of 316L stainless steel material, which is corrosion-resistant and does not react with sterilized items; Traceable material composition (furnace number and chemical analysis) for materials that come into direct contact with sterilized items; The flange and rack are made of 304 material.
Structure:
Circular reinforcement rib structure. The unique combination of interior and sandwich structure enhances the strength and stiffness of the main body. The sterilization room is designed with rounded corners, which is more conducive to cleaning and sterilization, ensuring sterility requirements; The welding seam of the sterilization chamber box adopts automatic welding, with single-sided welding and double-sided forming. The inlet steam pipeline connected to the inner chamber meets the 3D design requirements.
Emission Design:
The bottom of the sterilization room is designed with a concave shape, and the bottom discharge port is enlarged to facilitate the smooth discharge of condensate without retention.
- The sterilizer pressure vessel plate is cut using high-power laser cutting, with minimal heat impact on the cutting edge and no thermal deformation, completely avoiding thermal deformation during plasma cutting and edge collapse during punching and shearing. The cutting seam does not require secondary processing. Will not come into contact with the material surface and will not scratch the workpiece.
