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.
Sterilization Condition
Autoclaving
Only autoclavable syringe filters can be autoclaved. They can withstand autoclaving at 121°C (up to a maximum of 130°C) for 30 minutes, and this process can be repeated up to 20 times. However, we recommend using it only once for optimal performance after autoclaving. If customers wish to sterilize and reuse them, a thorough impact assessment is necessary.
Gamma Irradiation
Gamma irradiation involves exposing the filters to high-energy gamma rays, which can kill microorganisms such as bacteria, viruses and fungi. This method is typically used for large-scale sterilization in a relatively short time. Cobetter sterile syringe filters are gamma-irradiated and individually packed.
