Nest Scientific Biotechnology – advanced syringe filters

Sterile syringe filters made of PES (polyethersulfone) or PVDV (polyvinylidene fluoride) offered by the renowned brand Nest Scientific Biotechnology are an irreplaceable tool in the field of laboratory filtration processes. These advanced filters are designed to deliver the highest quality performance and precision when separating substances in both research and industrial laboratories.

Reliable resistance and durability

The materials from which sterile syringe filters are made, i.e. PES and PVDF, are well known for their exceptional chemical resistance and physical durability. Polyethersulfone (PES) is characterized by excellent thermal and chemical stability, which allows the filtration of even aggressive substances without the risk of degradation of the filter material. In turn, polyvinylidene fluoride (PVDF) is exceptionally resistant to organic solvents and aggressive chemicals, which is crucial when filtering samples with complex chemical composition.

Advanced production technology

Filtration using our syringe filters is not only efficient, but also precise, which is of great importance in the field of scientific research. A properly selected filter membrane allows for effective retention of particles, pollutants and microorganisms.

The Nest Scientific Biotechnology brand is famous for the innovation and quality of its products, and Sterile Syringe Filters with PES or PVDV are no exception. Using advanced manufacturing technologies and rigorous quality control processes, these filters are an indispensable tool in the hands of researchers and scientists, helping them achieve precise and repeatable results in their experiments and analyses.


  • Exceptional durability and resistance: The syringe filter housing is made of high-quality medical-grade polypropylene, which is one-time injection molded. This guarantees not only durability, but also resistance to high pressure, which allows safe operation even in demanding conditions. Excellent filtration efficiency: These filters offer high sterile filtration efficiency, achieving a microorganism reduction level (LRV) of level 7. This means that they are effective in eliminating 99,99999% of microorganisms, which is extremely important in laboratory applications.
  • Larger Filter Area: Complemented with a generous 4,9 cm² filter area, the filter provides efficiency and effectiveness, allowing more samples to pass through the filter in less time.
  • Variety of Membranes: Filters use a variety of membrane materials such as PES and PVDF. This allows you to tailor your membrane selection to your specific filtration needs, increasing flexibility and precision in the process.
  • Low Protein Binding: These filters are designed to minimize protein binding, which is crucial in many laboratory applications to ensure accuracy and repeatability of results.
  • High throughput and flow rate: Thanks to their design and advanced materials, these filters are characterized by high throughput and flow rate. This allows for quick and efficient filtration processes without loss of quality.
  • Reliable packaging: Each filter is placed in a separate, sterile paper-plastic packaging that is easy to open. This ensures that the filters remain sterile and ready for use at any time.
  • Free of DNA/RNA enzymes and pyrogens: These filters are free of DNA/RNA enzymes and pyrogens, which is important in applications where the presence of these substances cannot be tolerated to ensure sample purity and uninterrupted results.
  • Hydrophilic PES
    Low protein adsorption, high flow rate, wide pH range, high chemical compatibility, good heat resistance
    For general media and aqueous solutions, polar or medium polar solvents, neutral aqueous solutions.
