In the air invisible to our eyes, countless microorganisms float, which are closely related to human health and production safety. The floating bacterial sampler is like a precise "air detective" that captures bacteria and other microorganisms in the air through scientific means, providing key data support for environmental safety monitoring and becoming an important tool to safeguard safety in multiple fields.

Working Principle: The Scientific Mechanism of Accurate Capture

The floating bacterial sampler is designed based on the principle of particle impaction and isokinetic sampling theory. The built-in air pump inhales air at a stable flow rate of 100L/min±5%, and the wind speed at the sampling port accurately matches the ambient wind speed (such as 0.38m/s commonly in clean rooms), avoiding sampling errors caused by flow rate differences.

When air passes through the sampling channel, suspended microbial particles such as bacteria and fungal spores, due to inertia, impact and adhere to the surface of the petri dish coated with nutrient agar. Advanced models adopt graded impaction technology; for example, the fifth stage of the Anderson impaction method efficiently intercepts particles with a diameter of ≥0.3μm at a speed of 10.8m/s, achieving classified capture through the inertia difference of particles with different sizes, which greatly improves detection accuracy.

Application Fields: Safety Barriers for Multiple Industries

In the pharmaceutical industry, samplers regularly monitor the air quality in sterile workshops to ensure that microbial concentrations comply with GMP standards. A pharmaceutical company reduced the contamination rate by 60% and increased product qualification rate to 99.5% through continuous monitoring and environmental adjustment.

In the food processing field, it detects pollutants such as mold and yeast in dairy and meat product workshops. After application in a food factory, the shelf life was extended by 15 days, and customer complaint rate decreased by 40%.

In medical and health scenarios, real-time monitoring in operating rooms and ICUs can promptly identify potential infection sources. A hospital detected excessive Staphylococcus aureus through the sampler, and after system adjustment, the infection rate dropped from 2.1% to 0.3%.

In addition, during infectious disease prevention and control, it provides data support for pathogen monitoring in public places such as airports and stations; in the scientific research field, it is also a powerful tool for studying microbial distribution patterns and antibiotic resistance.

With its scientific working principle and wide range of application scenarios, the floating bacterial sampler has become an important bridge connecting the microscopic world and human safety. Its accurate monitoring makes invisible microbial pollution preventable and controllable, safeguarding the safe development of various industries.
