Why has Autoclave (High-pressure Steam Sterilization) Become the First Choice for Laboratory Sterilization?

In the daily work of laboratories and clinical laboratories, sterilization is a crucial link to ensure the accuracy of experimental data and the safety of personnel. Faced with various options such as dry heat sterilization, ethylene oxide sterilization, and irradiation sterilization, autoclaving (moist heat sterilization) stands out due to its high efficiency, reliability, and safety. As a professional manufacturer with more than 20 years of experience in the field of sterilization equipment, we will deeply analyze for you why the autoclave is the “sterilization butler” for scientific researchers!

Horizontal PK of Four Sterilization Methods: Which One Is the “Truly Ideal Choice” for Laboratories?

Five Core Advantages of Autoclaving (High-pressure Steam Sterilization)

1.The King of Efficiency: Shortening the Experimental Waiting Time
Using saturated steam at 121°C/103kPa, the sterilization process can be completed within 15-30 minutes, which is a significant acceleration compared to more than 10 hours required by dry heat sterilization.
Experimental data shows that for routine items such as culture media and instruments, the sterilization effect can reach a sterility assurance level (SAL) of 10^-6, far exceeding industry standards.
2.Full-scene Adaptability: Covering from Test Tubes to Biological Wastes

• Moisture-resistant and heat-resistant items such as culture media, reagents, and surgical instruments
• Laboratory consumables such as animal tissue samples and petri dishes
• Wastes

3.Strong Penetration Ability, Thorough Sterilization without Dead Corners
The steam in moist heat sterilization has a powerful penetration ability and can reach deep into porous materials and hard-to-reach areas to ensure thorough sterilization.
For example, for complex experimental instruments and porous culture medium containers, the autoclave can effectively kill the microorganisms hidden inside. However, due to the poor penetration ability of dry heat sterilization, it may lead to incomplete sterilization. This strong penetration ability makes the autoclave perform excellently when dealing with items of various complex structures, providing a reliable guarantee for the comprehensive disinfection of the laboratory.
4.Green Sterilization: Reducing the Risk of Chemical Pollution
Compared with chemical sterilization methods such as ethylene oxide sterilization, steam sterilization does not require the treatment of toxic gas residues, which is especially suitable for IVD laboratories and cell rooms with extremely high requirements for cleanliness.
5.Economical and Energy-saving: Lower Long-term Use Costs
The energy consumption of steam sterilization is much lower than that of dry heat equipment of the same specification, saving annual operation costs.
Autoclaving (high-pressure steam sterilization) deserves to be the “six-sided warrior” in the field of laboratory sterilization, relying on its unparalleled sterilization efficiency, wide material adaptability, reliable safety, verifiable sterilization effect, environmental protection and economic efficiency, as well as standardized operation procedures. It not only perfectly meets the strict requirements of modern laboratories for sterilization technology but also builds an invisible yet solid protective barrier for scientific research work with its stability verified over a century.
