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.

Are Cobetter sterile syringe filters pyrogen-free?

Cobetter sterile syringe filters are pyrogen-free.

Are Cobetter syringe filters Luer inlet/outlet? Are they fully compatible with syringes?

Cobetter syringe filters are equipped with Luer inlet/outlet, which are manufactured in accordance with GB/T 1962, ensuring reliable compatibility with standard syringes.

Can Cobetter PVDF syringe filters withstand DMSO?

Cobetter PVDF syringe filters are not recommended for filtering pure DMSO.
For DMSO applications, PTFE syringe filters are recommended, as they can withstand DMSO filtration at room temperature.

Which kind of syringe filter is recommended for precious protein samples?

For valuable protein samples, sterile PVDF syringe filters are recommended.
They provide high protein recovery rates (over 90% and even 99.9%) across a wide range of proteins.

What are the features and advantages of Cobetter syringe filters?

Fast flow rate.
No extractables.
Batch-to-batch consistency ensures reproducible experimental results.

Does Cobetter have suitable solutions for high-throughput filtration?

For high-throughput filtration, Cobetter recommends PES (Polyethersulfone) 96-well filter plates.

What is the shelf life of Cobetter syringe filters?

The non-sterile syringe filter has a shelf life of 3 years, while the sterile syringe filter has a shelf life of 2 years.
