PES (Polyethersulfone)
Johnson Test Papers’ PES Syringe Filters are purpose built with features designed to bring the highest levels of performance and purity to your research. These syringe filters contain polyethersulfone material. We offer a variety of membranes to offer separation and purification solutions for the majority of your laboratory needs. PES has a low affinity for proteins and low extraction losses with substantially faster flow rates than PVDF for critical filtration situations where high throughput is required with the lowest protein adsorption. It’s uniform pore structure offers higher mechanical resistance and chemical resistance compared to cellulose-type membranes. It is the first choice for the filtration of biological and pharmaceutical specimens, pre-filtration and filtration of buffers, culture media and sterilising filtration. The membrane is sealed within the polymer housing with using any adhesive. Each unit can be supplied sterilised with EtO of gamma radiation and is guaranteed pyrogen-free.
- Inherently hydrophilic
- Low pharmaceutical and protein binding characteristics
- Low extractables
- High filtration speed
- Superior thermal and chemical stability i.e. acids and bases
- Resistant against most hydrophilic fluids
- Chemical compatibility: pH 1 - 14
- Designed with a female Luer-Lok inlet and a male Luer slip outlet
- Some filters and individually wrapped and sterile, certified RNase-free, DNase-free and DNA-free - non-pyrogenic
- Water filtration
- Special chemical reagent filtration such as alkaline liquids and slightly organic solvents
- Preparation and sterile filtering of of protein based samples
- High speed filtration of tissue culture medias and other aqueous solutions
- High temperature liquid filtration
