Biologix Group Limited’s advanced technology

Sterile laboratory syringe filters made of PES, which are the work of the renowned brand Biologix Group Limited, represent excellent quality and advanced technology in the field of laboratory and scientific research. These filters are an indispensable part of the filtration process, contributing to precise and reliable results in laboratory analysis.

Their design is based on etersulfone polyester (PES), which makes them extremely effective at retaining microorganisms, particles and undesirable substances. It is a material with high mechanical strength, resistance to solvents and chemicals, which ensures long-term durability and reliability in a variety of laboratory conditions.

Filtration with these sterile PES syringe filters is not only effective, but also extremely precise. Their microporous structure makes it possible to separate particles of different sizes, which is crucial in analyses that require selective retention and concentration of samples.

Safety and reliability in research

Biologix Group Limited is a respected manufacturer of high-end laboratory equipment, which adds additional confidence in the quality of these filters. Their commitment to innovation and accuracy translates into tools that meet the demands of even the most advanced and sensitive scientific research.

In laboratory applications where precision, reliability and safety are key, sterile syringe filters made of PES from the Biologix Group Limited brand become an invaluable support, allowing researchers and scientists to focus on their research without worrying about the quality and reliability of the filtration process.


  • Use of PES material: laboratory filters made of resilient polyester (PES) have excellent compatibility with a wide range of chemicals and liquids. The PES material is resistant to organic solvents, making it possible to conduct tests under a variety of chemical conditions.High retention efficiency: Due to their microporous structure, PES filters provide effective retention of particles of various sizes. This enables precise separation and concentration of samples, which is extremely important in laboratory analysis.
  • Sterility: Biologix’s PES filters are sterile, which guarantees the purity of samples and minimizes the risk of contamination. This is crucial for accurate and reliable test results.
  • High throughput: Innovative manufacturing technology of PES filters makes it possible to achieve excellent throughput while maintaining high retention efficiency. As a result, they speed up the filtration processes, which is especially valuable during work that requires fast results.
  • Resistance to low and high temperatures: PES Biologix laboratory filters can withstand extreme temperatures, allowing them to be used in a wide range of research. They can be used both in analyses carried out under room conditions and at extreme temperatures.
  • Ease of use: PES filters are available in a variety of sizes and capacities to suit specific research needs. Their ergonomic design makes them easy to handle and assemble, which translates into smooth operation in the laboratory.
  • Safety: Biologix PES filters are free of toxic substances and potentially harmful ingredients. As a result, they can be used in biological and medical research without worrying about the impact on results and the health of workers.
