Cobetter hydrophilic PTFE syringe filters are HPLC-certified syringe filter that remove particles prior to instrumentation analysis(liquid chromatography or mass spectrometry analysis). They are made of modified hydrophilic PTFE membrane, which has very high chemical compatibility with both aqueous and organic solutions. When filtering aqueous solutions, there is no need for pre-wetting with solvent.

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.

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.
