Offering a broad range of filter units and bottle tops, our product portfolio includes wide membranes for faster flow and a certificate of quality in every case.

Our precut filter membrane discs are convenient to use and have low levels of extractables. Glass prefilters increase throughput of highly viscous or heavily particulated solutions, and some membranes are certified for water quality work.

Nalgene QC analytical filtration products are engineered to deliver best-in-class performance for microbiological monitoring and testing of water, food and beverage, raw materials, and finished product.

From filter forceps to bubble point testers, our accessories help increase the efficiency and integrity of your Thermo Scientific™ Nalgene™ filtration solution.

Available in a variety of sizes and membranes for both sterile and non-sterile laboratory applications. Nalgene helps meet your needs for sterile filtration, laboratory filtration, prefiltration, sample preparation, and gas venting.
