In the world of scientific research and analytical chemistry, syringe filters play a crucial role in sample preparation and filtration. Among the various types available, PTFE syringe filters have gained popularity due to their unique properties and versatility. One important aspect that scientists often consider when choosing a syringe filter is its resistance to UV radiation, especially in applications involving mass spectrometry and sensitive analyses. In this article, we will delve into the world of PTFE syringe filters, explore their resistance to UV radiation, and examine some popular brands such as Pall Acrodisc, VWR 28145 477, Sartorius 16532 K, Whatman PTFE syringe filter, Sartorius 16534K, Biofil syringe filter, Acrodisc syringe filters with Supor membrane, and Minisart syringe filter.
PTFE, short for polytetrafluoroethylene, is a synthetic fluoropolymer of tetrafluoroethylene. It is well-known for its exceptional chemical resistance, high thermal stability, and low coefficient of friction. These properties make PTFE an excellent choice for applications where strong acids, bases, or aggressive solvents are involved. PTFE syringe filters consist of a porous membrane made of PTFE that allows only the desired particles or solvents to pass through while filtering out contaminants, ensuring a clean and reliable sample for analysis.
In various scientific disciplines, including biology, chemistry, and environmental sciences, UV radiation is commonly employed for sterilization and detection purposes. Additionally, UV radiation is extensively utilized in chromatography and mass spectrometry analyses. Given this widespread usage, it is vital to consider the UV resistance of syringe filters, especially when dealing with sensitive samples or compounds prone to degradation upon exposure to UV light.
Polytetrafluoroethylene exhibits remarkable resistance to UV radiation. Unlike some other materials that may degrade or become brittle upon exposure to UV light, PTFE maintains its integrity and structural stability. This resistance ensures that the syringe filters made from PTFE remain robust and effective, even after prolonged exposure to UV radiation.
Mass spectrometry (mass spec) is a powerful analytical technique used to identify and quantify molecules based on their mass-to-charge ratio. It is crucial to maintain sample purity and integrity during the preparation process to obtain accurate results. PTFE syringe filters have become the filters of choice for mass spectrometry applications due to their ability to withstand harsh solvents and maintain consistent filtration efficiency under UV exposure.
Pall Acrodisc syringe filters are renowned for their quality and performance. These filters feature a PTFE membrane that offers excellent compatibility with a wide range of solvents, including aggressive organic solvents and strong acids. Pall Acrodisc filters are designed to provide low protein binding and are commonly used in research laboratories and pharmaceutical settings for critical filtration applications.
VWR is a well-established name in the scientific community, and its syringe filters have gained popularity among researchers. The VWR 28145 477 syringe filters boast a PTFE membrane that ensures optimal filtration efficiency and chemical resistance. These filters are well-suited for various applications, including sample clarification and particle removal.
Sartorius is a trusted brand in the field of laboratory equipment, and their PTFE syringe filters are no exception. The Sartorius 16532 K and 16534K syringe filters offer reliable filtration of aggressive solvents and chemicals. They are widely used in high-performance liquid chromatography (HPLC) and other analytical techniques where sample purity is critical.
Whatman, a division of GE Healthcare, is a renowned manufacturer of filtration products. Their PTFE syringe filters are designed to meet the demands of modern laboratories, providing consistent and reproducible results. The Whatman PTFE syringe filter is particularly useful in applications involving the filtration of non-aqueous samples and samples with high protein content.

The Biofil syringe filter with a PTFE membrane is ideal for applications involving aggressive solvents and high-temperature samples. Its UV resistance ensures the stability of the filter under intense UV radiation.
Acrodisc syringe filters with a Supor membrane are designed to combine the chemical compatibility of PTFE with the high flow rates of polyethersulfone (PES) membranes. The Supor membrane is a hydrophilic, low-protein-binding membrane that enhances the filtration process while maintaining PTFE’s UV resistance. These filters are commonly used in sample preparation for HPLC and other instrumental analyses.
Minisart syringe filters are known for their compact size and high-performance filtration. The Minisart syringe filter with a PTFE membrane is suitable for a wide range of applications, including filtration of organic solvents, aggressive chemicals, and samples with particulate matter. Its UV resistance ensures reliable and consistent results during UV-based sterilization and analysis.
In conclusion, PTFE syringe filters demonstrate remarkable resistance to UV radiation, making them a preferred choice in various scientific and analytical applications. The brands mentioned above, such as Pall Acrodisc, VWR 28145 477, Sartorius 16532 K, Whatman PTFE syringe filter, Sartorius 16534K, Biofil syringe filter, Acrodisc syringe filters with Supor membrane, and Minisart syringe filter, offer high-quality filters that maintain their integrity and filtration efficiency even under intense UV exposure. Scientists and researchers can confidently rely on these PTFE syringe filters to obtain clean and reliable samples for their critical analyses and experiments. Whether in mass spectrometry, HPLC, or any other application requiring chemical compatibility and UV resistance, PTFE syringe filters prove to be an indispensable tool in the laboratory.
