Membrane filters

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 pre-wetted with glycerol removed for convenience in 0.05 % sodium azide solution. Simply rinse away the preservative solution with DI water, load the sample and dialyze.

SEPARA integrates in one single device auto-sampler vial, filtration membrane, plunger, and cap/septa. The single step filtering process is efficient and saves time. Fast and simple to use. Reducing sample loss. After filtration the sample is ready to use in most standard autosampler. The pre-slit cap ensures easy and clean transfer of sample. 5 different septa material, PP vial with Ø 12 x 33 mm, Filtering capacity 0.48 ml, dead volume <30 µl, maximum operating temperature 50 °C

Filter handling for MF method testing has been revolutionized by the EZ-Pak membranes and dispensers. They combine the advantages of ready-to-use, sterile and individually packaged membranes.

Durapore® PVDF membranes are characterized by high throughput and high flow rate. To maximize recovery and minimize interaction with your sample, the membrane has very low protein binding.

Features & Benefits:

• Can be sterilized by ethylene oxide and gamma irradiation
• Available in different pore sizes

MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.

Features & Benefits:

• Manifold filter for biological and environmental monitoring applications
• available in various pore sizes
• white or black coloured
• Freely selectable whether with or without grid surface
• Compatible with ethylene oxide, gamma irradiation and autoclave sterilization methods

• Compatible with ethylene oxide, gamma irradiation and autoclave sterilization methods

In contrast to nitrocellulose, Immobilon membranes have a number of advantages. An optimized coloring capacity, a broad solvent compatibility and a lower background make the membranes your solution. Immobilon membranes do not rupture or curl and can be cut without breaking. Reprobing is also possible many times. The Immobilon NC membrane without surfactant, is perfect for not disturbing cell wall integrity during cell wall growth.

Features & Benefits

• Mixed cellulose matrix
• Recommended for colony lifts
