Hi-Flow^™ Plus membrane 75

Hi-Flow^™ Plus membranes are designed and optimized for use in rapid diagnostic lateral flow tests that require superior consistency and performance. Lateral flow tests facilitate quick and convenient detection/quantification of analytes such as antibodies and antigens present in biological samples, including blood, saliva, and urine. Hi-Flow^™ Plus membranes are ideally suited for such applications. Available in a variety of capillary flow times and backing options, choosing Hi-Flow^™ Plus membranes can improve assay performance and offer flexibility to meet a wide range of assay design requirements.

Hi-Flow^™ Plus 75 (HF075) is suitable for tests where speed is critical, the sample is plentiful, and sensitivity is not a concern. This Hi-Flow^™ Plus 75 pack comprises 11 slit rolls of 2 mil backed nitrocellulose membrane with a nominal capillary flow time of 75 seconds/4 cm.

• Hi-Flow^™ Plus membrane is a critical raw material suitable for use in a broad range of Lateral Flow test applications, including Infectious Disease testing (COVID-19, HIV, Influenza, Malaria, STDs, etc.), as well as in women’s health, biomarker detection, drugs of abuse testing, drug development, environmental testing, agricultural applications, food safety, product quality testing, and animal health.
