Cobetter hydrophilic PTFE syringe filters are made of modified hydrophilic PTFE membrane, which has very high chemical compatibility and pH resistance. They are suitable for use with aqueous solutions, aggressive organic solutions, and high temperature solutions. When filtering aqueous solutions, there is no need for pre-wetting with alcohol. Available in a range of pore sizes from 0.1μm to 5.0μm.

The housing is made of premium polypropylene which has a wide chemical compatibility. The Over molded design ensures higher operating pressures. Luer lock inlet/outlet offers leak-tight syringe connection.

Features

  • 13, 25and 33 mm diameter syringe filters
  • Broad chemical compatibility, high resistance to acid and alkali
  • Very low extractables
  • Low protein binding
  • Efficient mycoplasma, bacteria and particulate retention

Applications

  • Filtration of aqueous and organic solutions (including aggressive organic solutions)
  • Strong acid and alkali solutions
  • High temperature solutions
  • Particularly suitable for filtration of water-miscible organic solvents and disinfectant filtration

How to use a syringe filter?

Choose the right type of membrane material based on the properties of your sample. Be careful of the chemical compatibility to avoid extractables and leachables. Read this article about How to choose a syringe filter.

1. Load the sample into the syringe.

2. Attach the filter to the luer-lock of the syringe with a twisting motion. Make sure it is securely attached.

3. Filter the sample. Hold the syringe and filter vertically, and gently press the plunger to push the sample through the filter. Take care not to apply too much force or you may damage the filter.

4. Discard the used filter and repeat for the next sample.
