Laboratory Sterilization Solution - Leading a New Era of "Ecological Sterilization"
Fumigation is a technology that uses fumigant compounds to kill pests, pathogens, spores, or other harmful microorganisms in enclosed spaces. Fumigation can effectively eliminate stubborn microorganisms including spores. However, with the rapid advancement of technology, especially the emergence of "dry fog" sterilization systems, fumigation has become relatively outdated.
Dry fog sterilization overcomes many shortcomings of fumigation sterilization, such as complicated operation, excessively long sterilization time, and harm to human health and the environment, successfully leading a new era of "ecological sterilization".
The dry fog hydrogen peroxide sterilization system is an efficient, safe, and environmentally friendly laboratory sterilization solution. By converting hydrogen peroxide solution into micron-level dry fog particles, it achieves comprehensive sterilization of laboratory spaces, significantly reducing enterprise costs while fully meeting sterilization requirements and greatly shortening sterilization time.
Traditional fumigants are toxic, causing significant harm to humans or the environment, requiring special protection for operators.
Sterilization operation is complex, process difficult to control, requiring professional personnel operation.
Sterilization time is too long, traditional methods require several days, affecting normal laboratory operation.
The most notable feature of traditional fumigation is its low cost, but they all share some common shortcomings: toxic, causing significant harm to humans or the environment; complex sterilization operation, process difficult to control; excessively long sterilization time, which are precisely what modern enterprises find difficult to tolerate.
Meets high-level laboratory sterilization requirements, achieving 6-log reduction against Bacillus subtilis var. niger.
Significantly reduced concentration compared to traditional hydrogen peroxide, ensuring color steel plates and equipment are not corroded.
No residue after product disinfection, comprehensive verification data, compliant with environmental requirements.
5-micron dry fog effect, close to gaseous state, ensuring diffusion and disinfection effect for complex layouts.
The dry fog sterilization system uses specially designed atomizing devices to convert hydrogen peroxide solution into dry fog particles with a diameter of about 5 microns. These tiny particles undergo Brownian motion in the air, enabling uniform diffusion to every corner of the space, including areas difficult to reach by traditional methods.
Dry fog particles have the characteristics of non-settling, non-aggregating, and non-wetting surfaces, allowing them to remain suspended in the air for extended periods, fully contacting microorganisms, and destroying microbial cell structures through strong oxidation, achieving efficient sterilization.
Dry fog hydrogen peroxide sterilization systems are widely used in various laboratory environments, including biosafety laboratories, pharmaceutical clean areas, hospital operating rooms, laboratory animal facilities, and other places requiring high-level disinfection and sterilization.
The system can be safely used for surface and space disinfection of various materials including stainless steel, plastic, glass, floors, and walls, especially suitable for scenarios with strict material compatibility requirements.
The sterilization effect of the dry fog hydrogen peroxide sterilization system can be comprehensively verified, including sterilization efficacy verification, residue verification, and material compatibility verification.
Using Bacillus subtilis as the challenge test bacterium, a kill rate of 10³-10⁶ can be achieved, i.e., a reduction of 3-6 logarithmic units, proving the system's ability to kill various microorganisms during space sterilization.

The standard operating procedure of the dry fog hydrogen peroxide sterilization system is simple and intuitive:
Clean the sterilization space, transfer relevant personnel, close doors and windows
Place the sterilization equipment in a suitable position, connect to power source
Set sterilization parameters according to space volume, add disinfectant
Start the equipment, dry fog hydrogen peroxide evenly diffuses throughout the space
Ventilate after sterilization completion, detect residual concentration
The entire sterilization process takes only 2-6 hours, significantly shortening sterilization time compared to traditional fumigation methods, improving laboratory utilization efficiency, while the sterilization effect meets high-level laboratory requirements.
