Answer:One 20 mm-wide, 100 m-long roll is supplied.
Answer:The CN 140 nitrocellulose membrane is supported on clear 100 µm polyester backing.
Answer:The membrane grade, backing type and 100 m length match; the web width is 20 mm rather than 25 mm.
Sartorius Unisart CN 140 backed nitrocellulose membrane is a roll-format protein-binding substrate used in manufacturing and development of lateral-flow and other membrane-based rapid assays. The 20 mm-wide variant is supplied as a single 100 m roll with a clear 100 µm polyester support layer. Compared with an unbacked membrane, the backing improves physical support during reel processing, reagent line dispensing and cutting into test strips. Nitrocellulose provides a porous matrix for passive transport of sample and immobilization of capture reagents, while final analytical sensitivity depends on antibody chemistry, strip components and running buffer. The manufacturer lists a maximum of three splices for this configuration, so converting operations should accommodate splice detection or rejection where relevant. Verify coating and drying parameters on the actual membrane lot. The membrane is intended for assay construction and should not be described as a sterile filter with a specified bacterial-retention rating.
