Cobetter hydrophobic PTFE syringe filters are made of native chemically inert hydrophobic PTFE membrane with high chemical compatibility. These filters are ideal for venting and gas filtration, and the clarification and sterilization of organic solutions. For filtration of aqueous liquids pre-rinsing with a solvent is necessary.
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.
