Asymmetric depth filters, made of materials such as polyethersulfone (PES), have an open matrix structure at their top, and a finer matrix structure towards the bottom. This gradient of porosity initially traps large particles and acts as a pre-filter for the denser material underneath, maintaining flow.
With PES syringe filter membrane mechanically strong character, it can handle high-temperature liquids, with great flow rate (better than PTFE), and low protein binding. With these features, PES syringe filters offer superior performance for use with biological samples and media culture.
PES is well suited for use in separation membranes because of its high mechanical properties and broad chemical stability. Both of these functions derive from the polymer’s chemical structure. In the case of water filtration, the hydrophilic nature of PES contributes superior water permeability and wettability to separation membranes.
The cellulose acetate and PES syringe filters have particularly low adsorption which ensures minimal loss of proteins and preservatives. The filter geometry is designed for maximum sample throughput with low back pressure.
Materials of Construction: Media: Cellulose Acetate, Nylon, Polyethylene, PES, Polypropylene, Glass Fiber, and PTFE Autoclave Cycles: 10 times @ 257°F/125°C for
filtration through various pore sizes and membrane filter materials was the criteria used to determine suitability. The study results indicated that Polyethersulfone (PES; 0.2 µm) was the best of the filters studied in terms of adsorption as well as retention of
SLHV033RS) can be used to clarify lentivirus and 0.2um Millex GV syringe filters (Cat. SLGV033RS) for sterilizing. PES Express Plus (PES): Use for faster flow (0.2um Millex GP, Cat.
Simsii focuses to create and produce high-end disposable syringe filters and membrane filters that are easy to use and will serve all your laboratory filtration needs.PTFE Filter is popular among all.
Results may vary. Columns last 111 times longer than without filtration. A 0.05% microsphere suspension (average diameter 0.31 μm) in 0.002% TritonuX-100 (prepared from a 10% w/w polymer stock), was filtered using either 0.2 μm Acrodisc MS syringe filters or 0.45 μm Acrodisc PSF syringe filters with nylon membrane.
Nest syringe filters have pore size either 0.22μm or 0.45μm, and diameter 13mm or 25mm, with membrane materials either with PES or PVDF membranes. For sample volumes of 2mL to 100mL Retention volume <115µL Maximum operating temperature: 100°C autoclave at 125°C
Choose the Whatman filter that suits your applications and goals: • D/XG syringe filters process three to seven times more sample volume, which decreases hand pressure and increases efficiency. The novel pre-filtration stack is ideal for hard-to-filter samples.

The minispike outlet, available on 13 mm PTFE, Nylon, GH Polypro and PVDF Acrodisc ® syringe filters, allows for easy dispensing into autosampler vials. Membrane Design Membrane Type (PTFE, GHP, PVDF, Nylon) — Typically, the first step in selecting a suitable filter is to choose a membrane that is chemically compatible with the sample (see chart opposite).
