Membrane filters

Applications:

• Excellent for gravimetrical analysis
• Especially for aqueous solutions
• Ideally suitable for contamination test

• Economical
• Constant weight
• Hydrophilic
• Not sterile
• Can be used up to 125 °C
• Autoclavable up to 121 °C

SafetySpace™ Filter Tips leave more space between the sample and the filter than conventional filter tips. This allows pipetting any type of liquid or using any pipetting technique without the risk of the precious sample absorbing into the filter. In effect, this secures 100% sample recovery and thus greater accuracy. Particularly suitable for pipetting foaming liquids such as buffers and proteins, pipetting solvents, multiple dispensing functions of electronic pipettes, reverse pipetting. Certified DNase, RNase and endotoxin free....
