Membrane filters
Dialysis tubing closures Spectra/Por, PP
Standard and Weighted Spectra/Por Closures provide a leak-proof seal for dialysis tubing while aiding in sample buoyancy and vertical orientation. They are available in 23, 35, 55, 75 and 90 mm sealing widths and a variety of colors for easy sample identification. Closures are autoclavable....
Membrane Filter Dispenser, Microsart® e.motion
With this dispenser you can choose between three operating modes. Operation by push button, sensor or foot switch. With the model 16713----BO (Art no. 6.289 058), wireless operation is also possible only with battery.
- Capacity for up to 250 membrane filters
- Cleaning with standard disinfectants possible
- Low weight and convenient handle for easy transport
In-line filters Midisart® 2000
For sterile ventilation of fermenters, culture vessels, etc. or to act as a water barrier between the suction flask and the vacuum pump in filtration applications. The supported PTFE membrane within a PP housing gives excellent chemical resistance. Filter in either direction (3 bar max. pressure).
- Stepped horse-barb of 6-12 mm on either sides
- sterile single packed filters, autoclavable
Membrane filters Polytetrafluoroethylene PORAFIL®TE
Membranes of polytetrafluoroethylene (PTFE) are particularly suited for aggressive media, since they are chemically inert towards aqueous and organic solutions as well as towards concentrated acids and bases. These membranes are hydrophobic, thus the pressure for filtration of aqueous solutions has to be higher than the breakthrough pressure. PORAFIL...
Membrane filters type 113, cellulose nitrate
White. Very low content of extractable materials. Weight constant after 60 minutes of drying at 105 °C. Suitable for residue analysis, microscopic viewing in incident or transmitted light, chemotaxis, x-ray fluorescence, spectrometry and gravimetric analysis. Autoclavable at 121 °C. Other pore sizes and formats are available on request....
Membrane filters, Grade TE, PTFE with support
Applications:
- Ideal venting filter for all applications
- For aggressive media and cryogenic liquids
- Separation of free water from organic solutions
- Outstanding as gas/liquid barrier
- Filtration of air and (hot) gases
Membrane Filter Microsart® @filter units, CN
Microsart ® @filter 100 and 250 filter units are a sterile and ready-to-use combination of funnel made of PP with 47 mm diameter, filter base and gridded membrane in one unit. They have been specifically developed for the detection and enumeration of microorganisms in pharmaceuticals, cosmetics, food, beverages, water and other liquids. The membrane filters can also be used in conjunction with Sartorius Stedim Biotech nutrient board discs....
Membrane filters Cellulose acetate PORAFIL®CA
These membranes of cellulose acetate have a low protein binding capacity and are suited for aqueous and alcoholic media. The membranes are hydrophilic and can be used for hot gases up to 180 °C. They can be sterilised....
Membrane filters PORAFIL®CM
Membranes of cellulose mixed esters are ideal for gravimetric analysis. They are particularly suited for aqueous solutions. The hydrophilic membrane is thermally stable to 125 °C and can be autoclaved at 121 °C. This membrane is often used for contamination tests....
Membrane filters Nitrocellulose PORAFIL®NC
PORAFIL ® NC membranes are made from cellulose nitrate. They are easily wettable and suited for filtration of aqueous solutions. In dry atmosphere these membranes are thermally stable to 125 °C and can be autoclaved at 121 °C....
Pre-wetted RC Dialysis Tubing Spectra/Por® 6
Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis tubing. This tubing is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated, including sample preparartion, desalting, buffer exchange, pH change, protein purification. Offering a good chemical compatibility, Standard Grade RC can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO. Standard RC can tolerate pH 2 to 12 and temperatures 4 to 121 °C...
