Product Information: CIRCLES, NITRATE, MEMBRANE, AE99 8UM 25MM
Manufacturer Part # 10400106
Description
- Non-Sterile Cellulose Nitrate Membranes
- Cellulose Nitrate Membrane Circle, plain
- Narrow pore size distribution for improved surface capture and analysis
- Low levels of extractables to ensure sample integrity
- Recommended for the majority of routine applications, this membrane is manufactured under strictly controlled conditions
- The user will benefit from the performance improvements that are now available in Whatman membrane filters, including very narrow pore size distribution and low levels of extractables
- Higher strength and flexibility:
- Most membranes are inherently brittle and difficult to handle
- It is not uncommon for filters to be damaged during loading into holders or while in use
- Whatman cellulose nitrate membrane filters have a noticeably improved flexibility and are made to tolerate abuse during handling, loading, and autoclaving without sacrificing integrity
- These membranes are among the strongest of their type available, as measured and compared by burst pressure tests
- Low extractable levels:
- The level of extractables in membrane filters has become more important with advances in filtration or adsorption techniques
- In particular, pharmaceutical, immunological, and biomedical tissue culture and trace analysis applications can be adversely affected by high extractable levels
- Whatman cellulose nitrate membrane filters have a low level of extractables, generally below that of other membranes of a similar type
- Narrow pore size distribution:
- One of the major features of Whatman membrane filters is the narrow distribution of pore sizes
- The rated pore size of these membranes is closely controlled due to the advanced manufacturing and control system
- Additionally, the batch-to-batch variation is minimized providing more consistent laboratory results
- Increased temperature stability:
- Membrane filters are normally autoclaved at 121°C without loss of integrity
- Cellulose nitrate membranes are supplied as circles, sheets, or reels
- Reduced shrinkage:
- Excessive shrinkage can cause problems during autoclaving and is often the cause of membranes tearing in their holders after autoclaving
- It may also cause a reduction in flow rate and total throughput
- Whatman membranes exhibit a low shrinkage during autoclaving
- White plain filters:
- This is the standard membrane filter for the majority of laboratory applications involving particles and cells in the range of 0.1 µm to 12.0 µm
- The residue after filtration is found to be almost completely on the surface of the membrane and allows physical recovery of deposits and microscopic examination
