The nitrocellulose membrane is one of the most important components of the rapid lateral flow test. The capillary velocity of the membrane is particularly critical for lateral flow functionality because it affects sensitivity, specificity, response time, and test costs. Each type of membrane in our Unisart® series of nitrocellulose membranes has a specific range of capillary velocity. Our Unisart® CN 95 membrane is suitable for high viscosity samples and is the ideal solution when a fast response is desired. In contrast, test strips with our Unisart® CN 180 membrane have the longest response time, but the tests will show the highest sensitivity, while the other Unisart® CN 110, CN 140 and CN 150 membranes provide a different optimum for speed, specificity and sensitivity. Our wide selection of Unisart® membranes allows you to find the one that best suits the requirements of your diagnostic test. | ![]() |
