Membrane filters

Type 250. Polyamide, white. For filtration of alkaline solutions and organic solvents.

Material: Anopore^®. White.
The inorganic membrane Anopore^® consists of high-purity aluminium oxide and can be used for a wide range of applications. The unique material has a precise, non-deformable honeycomb structure with a narrow pore size distribution range that guarantees very efficient particle retention. In addition, the membrane has a low protein binding capacity, minimal autofluorescence, is non-toxic and supports cellular growth.

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
RC dialysis tubing supplied dry with glycerol humectant for easy handling and manipulation. Soak in DI water for 30 minutes to remove glycerol. Contains trace levels of heavy metals and sulphides.

These cellulose mixed ester membranes are reinforced with a polyester fabric. Their filtration properties are very similar to membranes PORAFIL^® CM, however, they are mechanically much more stable.

Ready-to-use dialysis device with screw cap for ultimate convenience for small volume dialysis. Easy loading and recovery. No needles, closures, knots, buoys, pontoons, or weights required. Made with Biotech CE membrane in 9 MWCO"s (0.1 to 1000 kD) and 3 volume sizes (1, 5 and 10 ml).

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.

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

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

The very low adsorption membranes are hydrophilic, solvent-resistant (pH 3-12) and therefore suitable for the particle removal from solvents.
