Answer:The roll is 25 mm wide and 100 m long, with one roll per supplied unit.
Answer:Yes. It has a clear polyester backing with a specified thickness of 100 µm.
Answer:It is a protein-binding nitrocellulose substrate for rapid-test and lateral-flow assay construction, not a sterile liquid filtration membrane.
Sartorius Unisart CN 140 is a backed nitrocellulose membrane designed as an immobilization substrate for protein-based rapid tests and lateral-flow assay development. This version combines the CN 140 nitrocellulose matrix with a clear 100 µm polyester backing and is supplied as one roll 25 mm wide by 100 m long. The backing provides mechanical support during membrane handling, converting, strip cutting and integration with other lateral-flow components. Its microporous nitrocellulose structure offers protein-binding properties suitable for antibody test-line and control-line deposition. The documented roll configuration allows up to three splices; downstream users should define acceptance criteria for splice locations and web uniformity. During assay development, optimize dispensing density, drying conditions, blocking chemistry and wicking behavior with the full strip assembly. This diagnostic-assay substrate is not a rated sterilizing filtration membrane, and no pore-size removal claim should be inferred from the CN 140 designation.
