The 33mm sterile syringe filter is a large-diameter, single-use filtration device designed for sterile or particle filtration of high-volume liquid samples, typically up to 200 mL or more, depending on the sample type. With its extended surface area, it provides faster flow rates, longer filter life, and lower clogging risk, making it highly suitable for biotech, pharmaceutical, environmental, and analytical applications where sample purity and sterility are critical.
