Nitrocellulose (NC membrane) 7190-002 1.0um microporous filter membrane

Nitrocellulose membrane( NCmembrane)

Recommended for most daily applications, this film is produced under strictly controlled conditions.Whatman™The nitrocellulose membrane ensures the nonNarrow pore size distribution and extremely low extraction and dissolution levels, withThe biocompatibility can benefit end-users.

Higher strength and flexibility

Most membranes are inherently brittle and difficult to handle, often damaged during loading into filters or use.Whatman™The toughness of nitrocellulose membrane has been significantly enhanced, and it can maintain the integrity of the membrane during the entire process of picking, loading, and sterilization operationsThe integrity of the body has been tested and compared for resistance to burst pressure,Whatman™Nitrocellulose membrane is one of the similar filter membranesResilient.

Low dissolution level

With the advancement of filtration or adsorption technology, the level of membrane leaching has become increasingly important. Especially in the fields of pharmacy, immunology, and biologyIn terms of textile cultivation and trace analysis applications, high dissolution levels can lead to negative effects.Whatman™Dissolution level of nitrocellulose membraneGenerally lower than other membranes of the same type.

Accurate aperture

Whatman™An important characteristic of a filter membrane is its high pore size accuracy. The production and control systemAccurate narrow aperture distribution can be achieved, and the variation of inter batch differences is minimized, ensuring consistent experimental results.

Increased temperature stability

The filter membrane can be used 121oCMaintain integrity after high-temperature sterilization. Nitrocellulose film comes in different specifications such as circular, square, and scroll.

Reduced shrinkage rate

Excessive shrinkage during disinfection can cause problems, and membrane tearing often occurs in the filter after disinfection, which may also lead to flowReduced speed and overall filtration capacity.Whatman™The shrinkage rate of the filter membrane is very low during the disinfection process.

Types of filter membranes

Smooth white filter membrane

This is the standard filter membrane used in most laboratory applications, for0.1μm-12.0μmParticles and cells of varying sizes.Most of the filtered residue remains on the surface of the membrane and can be easily physically recovered and observed under a microscope for precipitation.

mesh filter membrane

The mesh filter membrane makes it easy to count particles, microorganisms, and colonies. If you need a mesh film, please refer to the mixed cellulose ester film.
