Cobetter Nylon syringe filters are made of naturally hydrophilic Nylon66 membrane and are widely used for clarification or particle removal under non-sterile conditions and compatible with a broad range of solvents including aqueous and organic solutions. They are the economical and popular choice for filtering most general laboratory solutions.


· Compatible with both aqueous(non-acidic) and organic solutions

· Broad chemical compatibility and flexibility

· Low extractables or leachables

· High protein binding

· High mechanical stability

· High dirt loading capacity

· HPLC, GC, or dissolution sample analysis


· Clarification or sterilization of aqueous and organic solutions

· Filtration of mixed solvents and solvents

· General sample preparation

· Clarification or particle removal before HPLC analysis

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.
