Should You be Using a Glass Pre-filter Syringe Filter?

Effective sample filtration enhances the quality and consistency of analytical results, while also extending the lifespan of your instrument's replacement parts. One commonly used filtration method among chromatographers is the syringe filter, known for its affordability and ease of use.

Syringe filters are available in various membrane types, pore sizes, and diameters, which can make choosing the right one seem daunting. However, we simplify the selection process in a previous blog post: How to Choose a Syringe Filter.

What About Extra Dirty Samples?

For extra dirty samples, such as ethanol applications, a glass prefilter can be used to aid with flow and reduce some of the pressure buildup that can happen from the sample filtrates building up on the membrane. While this can greatly aid in filtration for samples that won’t easily pass through a regular syringe filter, we really only recommend the glass pre-filter for applications with a great deal of particulate matter. This is because the glass pre-filter does add an additional cost, most applications only need one layer of filtration before injection.
