NC ROLL, 270mm X 60M, EACH

Is very similar to the CN140 unbacked but supported with a polyester backing, allowing a very easy handling and reel to reel processing. Its application side is slightly different from that of the CN140 backed and its capillary speed is slightly slower. Thus the CN150 is the slowest and the most sensitive membrane of the UniSart family.

Is very similar to the CN140 unbacked but supported with a polyester backing, allowing a very easy handling and reel to reel processing. Its application side is slightly different from that of the CN140 backed and it’s capillary speed is slightly slower. Thus the CN150 is the slowest and the most sensitive membrane of the UniSart family. This membrane is used in many different LF tests. The CN150 unbacked has the following features:

  • Nitrocellulose microporous membrane
  • Capillary speed of around 150 sec/4cm (around 8µm pore size)
  • Supported onto a 100µm clear polyester allowing use in reel to reel equipment
  • Extensive QC
  • 100% visually checked for surface defects
  • Long shelf life (3 years)
  • Many roll widths available on stock

Manufacturing and lot information

UniSart cellulose nitrate membranes are formed using an air casting process, where solvents are evaporating from a mix of different cellulose nitrate polymers and additives to eventually form the unique microporous structure needed for LF strip. Test performance is strongly dependent on internal membrane structure and surface quality. Our specifically designed casting machines together with a patented surface finishing process allow us to manufacture reproducible membranes with outstanding consistency and performance.Certificate of Quality
A certificate of Quality is delivered in each membrane box.

Quality Assurance

Consistent high quality of Sartorius membranes is assured by following a strict quality assurance system.
All raw material types are selected and approved in accordance with current regulations, recommendations, inhouse guidelines and specifications coming from national and international standards as well as from our Research and Development Department.
State of the art production practices following applicable cGMP guidelines including encapsulated and controlled production areas and employee hygiene ensure optimal quality of the final product.Complete Traceability
The type and lot numbers are printed on the label of the protective plastic case/bag and on the label inside the membrane roll core. The traceable lot number allows convenient retrieval of all data compiled on the material used, production steps and QC tests.For example, on the roll label, you will see:

Storage and handling, safety data and shelf life of UniSart membranes

Attention: Cellulose nitrate membranes are highly flammable. Their flashpoint is approx. 180°C. Always keep these membranes separated by the interleaving paper as originally supplied. The unbacked cellulose nitrate material is considered as a dangerous good according to UN3270.
