When working with substances that are especially viscous, prefiltration is an option for syringe filters. Opting for prefiltration in a syringe filter is an excellent choice when working with a more hard to filter or particularly thick substance.
Here at Tisch Scientific we have a wide variety of syringe filters with prefiltration to suit you and your team’s every need. This guide is to help you understand this process and your options better.
How Do You Choose the Correct Syringe Filter?
A syringe filter is a single-use membrane based filter used to remove impurities from a substance before analysis. The filter catches these impurities and removes them from the sample.
There are many different factors to consider when choosing a syringe filter for your application. So how do you know which syringe filter is right for your application? We have helpful guides for chemical compatibility and a guide to filter media selection.
If your application requires prefiltration we have a wide variety of syringe filters with prefiltration.
All About Pre-Filters
What exactly is a pre-filter? A pre-filter is an extra layer on a syringe filter that helps to filter out particles that wouldn’t be caught by standard filtration. Applications where a liquid sample is particularly thick or a large amount of contaminants need to be removed may call for prefiltration. If you know you need prefiltration for your application you may also be wondering what specifically you need to be looking for.
Glass Fiber Pre-Filters
Glass fiber is a commonly used material for pre-filtration. Glass fiber pre-filters and glass microfiber pre-filters are ideal for hard to filter substances with a high volume of solids. Glass fiber pre-filters come in various grades to fit different purposes. You can find more about them here.
Many pre-filters are fitted with multiple layers to filter out even the hardest to filter solutions. The various layers allow for more particles to be caught and kept out of the sample.
