Pes syringe filters are commonly used in laboratory applications to filter out particles and microorganisms from various solutions. They are made of polyethersulfone (PES) membrane, which is a hydrophilic membrane that offers high flow rates and low protein binding. The filters come in different pore sizes, ranging from 0.22μm to 5μm, and are compatible with a wide range of solvents and solutions. As with any laboratory equipment, there are frequently asked questions (FAQs) about pes syringe filters that users may have. In this article, we will address some of the most common FAQs related to pes syringe filters.
A PES syringe filter is a type of filter made from polyethersulfone (PES) membrane that is used to remove contaminants and particles from a liquid sample.
The pore size of a PES syringe filter typically ranges from 0.22 microns to 0.45 microns.
The maximum operating temperature of a PES syringe filter is usually around 60°C.
The maximum operating pressure of a PES syringe filter varies depending on the size and manufacturer, but is generally between 4-7 bar.
Yes, PES syringe filters can be sterilized by autoclaving, gamma irradiation or ethylene oxide sterilization.
PES syringe filters can be used for a variety of samples, including aqueous solutions, biological fluids, and aggressive organic solvents.
You should consider the sample type, volume, and the size and type of particles you want to remove. You should also select the appropriate pore size and filter diameter.
To use a PES syringe filter, attach it to the end of a syringe and apply pressure to the plunger to force the sample through the filter.
PES syringe filters are typically designed for single use only and should not be reused.
PES syringe filters can be disposed of as regular waste, but it is recommended to check your local regulations for proper disposal procedures.
Hydrophilic PES syringe filters are designed to attract water and other polar substances, while hydrophobic PES syringe filters repel water and attract nonpolar substances.
The flow rate of a PES syringe filter depends on the size of the filter, the viscosity of the sample, and the pressure applied to the syringe.

The recommended filter diameter for PES syringe filters depends on the volume of the sample to be filtered. Common sizes are 13mm and 25mm.
Yes, PES syringe filters are commonly used for sterile filtration of cell culture media, but it is important to use a filter with a pore size that will not remove necessary components from the media.
To prevent air bubbles from getting trapped in a PES syringe filter, prime the filter by pushing a small amount of sample through the filter before adding the full volume.
PES syringe filters are generally not recommended for use with aggressive solvents like strong acids or bases. Check the chemical compatibility chart provided by the manufacturer to ensure compatibility with your specific solvent.
Yes, PES syringe filters are commonly used for sample preparation for mass spectrometry analysis to remove contaminants and improve the accuracy of results.
Yes, PES syringe filters can be used with viscous samples, but a larger pore size or larger filter diameter may be needed to maintain adequate flow rate.
Yes, PES syringe filters can be used for protein purification, but it is important to choose a filter with a pore size appropriate for your specific application.
To prevent filter clogging during filtration, use the appropriate pore size and filter diameter, and avoid overloading the filter with sample.
Yes, PES syringe filters can be used with non-aqueous solvents, but you should check the chemical compatibility chart provided by the manufacturer to ensure compatibility with your specific solvent.
Yes, PES syringe filters can be used with samples containing detergents, but it is important to choose a filter with the appropriate compatibility for your specific detergent.
To prevent filter blowouts during filtration, avoid using excessive pressure or force, and use the appropriate pore size and filter diameter for your sample.
Yes, PES syringe filters can be used for sterile filtration of vaccines, but it is important to choose a filter with the appropriate pore size and ensure that the filter is properly sterilized before use.
Yes, PES syringe filters can be used for sample preparation for PCR to remove contaminants and improve the accuracy of results.
To prevent filter cross-contamination during filtration, use a new filter for each sample, and use separate syringes for each sample to avoid contamination from the syringe.
