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 indispensable tool in the field of laboratory filtration processes. These advanced filters are designed to deliver superior performance and precision when separating substances in both research and industrial laboratories.

Reliable resistance and durability

The materials from which the sterile syringe filters are made, i.e. PES and PVDF, are well known for their exceptional chemical resistance and physical durability. Polyethersulfone (PES) has excellent thermal and chemical stability, which allows filtration of even aggressive substances without the risk of degradation of the filter material. Polyvinylidene fluoride (PVDF), on the other hand, is distinguished by its exceptional resistance to organic solvents and aggressive chemicals, which is crucial when filtering chemically complex samples.

Advanced manufacturing technology

Filtration with 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 effective retention of particles, contaminants or microorganisms.

The Nest Scientific Biotechnology brand is renowned for the innovation and quality of its products, and Sterile Syringe Filters made of 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 reproducible results in their experiments and analyses.


  • Exceptional durability and resilience: the syringe filter housing is created from high-quality medical-grade polypropylene, which is injection molded once. This guarantees not only durability, but also resistance to high pressure, allowing safe operation even in demanding conditions.Excellent filtration performance: These filters offer high sterile filtration performance, achieving a level of microorganism reduction (LRV) of 7. This means that they are effective in eliminating 99.99999% of microorganisms, which is extremely important in laboratory applications.
  • Larger filter area: Juxtaposed with a generous filtering area of 4.9 cm², the filter provides efficiency and effectiveness, allowing more samples to pass through the filter in less time.
  • Diversity of membranes: The filters use a variety of membrane materials, such as PES and PVDF. This allows you to tailor the choice of membrane 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 critical in many laboratory applications to ensure accuracy and reproducibility of results.
  • High throughput and flow rate: thanks to their design and advanced materials, these filters have high throughput and flow rate. This allows the filtration processes to be carried out quickly and efficiently without loss of quality.
  • Reliable packaging: each filter comes in a separate, sterile paper and plastic package that is easy to open. This ensures that the filters remain sterile and ready for use at all times.
  • No 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.
  • PES Hydrophilic
    Low protein adsorption, high flow rate, wide pH range, high chemical compatibility, good heat resistance
    For general nutrient solutions and aqueous solutions, polar or moderately polar solvents, neutral aqueous solutions.
    It should not be used for chloroform, esters, amides and strong acids or strong bases.
  • PVDF Hydrophilic
    Wide practicality, good oxidation resistance and heat resistance
    It can be used for aqueous solutions and most solvents, including strong non-polar solvents. Ideal for HPLC and GC preparations
    Should not be used for strong acids and bases
