Product Description

Circular Bacterial Viral Filter Paper Low Pressure Drop 30l/min/100cm2 Flow Rate Tracheostomy Breathing Filter

Product Description:

The Bacterial Viral Filter Paper is a cutting-edge solution designed to provide the utmost protection against the transmission of infectious agents. This sterile EO (ethylene oxide) disposable filter is crafted with precision and care, ensuring that every sheet meets the highest standards of quality and efficacy. Manufactured by a reputed china factory, this product stands out for its exceptional performance in bacterial and viral filtration applications.

Each filter is circular in shape, which allows for uniform filtration and easy handling. The shape is ideal for fitting into various devices and equipment, without compromising on the efficiency of filtration. The design is not just about aesthetics, as the circular shape also contributes to the overall functionality of the filter, ensuring that it provides a consistent barrier against contaminants.

With a diameter of 50mm, the Bacterial Viral Filter Paper is sized to fit a range of filtration systems. This universal size is carefully chosen to ensure that the filter can be widely used across different platforms, making it an incredibly versatile tool in the fight against bacterial and viral transmission. The 50mm diameter is a standard size that provides ample surface area for effective filtration without being too bulky or unwieldy to incorporate into existing systems.

Understanding the critical nature of sterile environments, the Bacterial Viral Filter Paper can withstand max sterilization temperatures of up to 121℃. This feature guarantees that the filter can be sterilized using high-temperature steam, a common and effective method for rendering medical equipment and supplies free from viable microorganisms. The ability to withstand such temperatures not only assures sterility but also extends the filter's usefulness by allowing for repeated sterilizations without degrading its structural integrity or performance.

The filter boasts a thickness of 3mm, providing a robust barrier against microbes. This specific thickness has been optimized to balance filtration efficiency with airflow, ensuring that the filter does not restrict necessary ventilation while still capturing a high percentage of bacteria and viruses. The 3mm thickness is also a testament to the durability of the filter, as it is less likely to tear or puncture than thinner alternatives, offering an additional level of security in critical applications.

Intended primarily for the application of bacterial and viral filtration, this bacteria filter sheet is a vital component for medical devices, laboratory equipment, and any other systems where sterile air or gas is a requirement. Whether it's used in clinical settings, research facilities, or industrial applications, the Bacterial Viral Filter Paper is designed to trap and remove a wide range of pathogens, providing a safe and clean environment. Its efficacy in preventing the spread of disease makes it an indispensable tool in healthcare and other fields where contamination control is paramount.

The china factory producing the Bacterial Viral Filter Paper adheres to stringent quality control processes, ensuring that each filter is free from defects and meets global standards. The use of sterile EO disposable filters underscores a commitment to safety and hygiene, as each filter is intended for single use and then disposed of, eliminating the risk of cross-contamination between uses. This single-use approach aligns with the best practices in infection control, making the Bacterial Viral Filter Paper a trustworthy choice for professionals concerned with maintaining the highest levels of cleanliness and patient care.

In summary, the Bacterial Viral Filter Paper is an essential component that offers reliability, efficiency, and peace of mind in applications requiring sterile filtration. Its circular shape, optimal diameter, high sterilization temperature tolerance, appropriate thickness, and its role as a bacteria filter sheet make it a top choice for those seeking the highest standard in filtration products. Manufactured by a china factory with a reputation for excellence, users can be assured of the quality and performance of this indispensable filter with every use.
