Cobetter high throughput syringe filters are constructed of polypropylene housing with a prefiltration membrane with pore sizes ranging from 0.45μm to 0.8μm. This construction prevents the build-up of back pressure typically caused by the blocking of an unprotected membrane.

Cobetter high throughput syringe filters can process three times more sample volume than standard syringe filters and have extended lifespan.

These autoclavable syringe filters 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 single-use for optimal performance. If customers wish to sterilize and reuse them, a thorough impact assessment is necessary.

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.
