What is a Fractionation syringe filter?
Fractionation syringe filters are a specialized type of syringe filter used for the separation and purification of small molecules or biomolecules based on their size or molecular weight.
These filters typically have a range of pore sizes, allowing them to separate the sample into different fractions based on the size of the molecules present.
Fractionation syringe filters are commonly used in analytical chemistry, biochemistry, and biotechnology applications. They can be used to isolate and purify specific components of a sample or to separate molecules for further analysis or characterization. For example, fractionation syringe filters can be used to separate peptides or proteins based on their molecular weight or to isolate small molecules from a complex mixture.
The process of fractionation typically involves passing the sample through a series of fractionation syringe filters with progressively smaller pore sizes. As the sample passes through each filter, molecules that are too large to pass through are retained, while smaller molecules pass through to the next filter in the series. This process can be repeated several times to obtain highly purified fractions of the desired molecule.
Fractionation syringe filters can also be used in combination with other separation techniques, such as chromatography, to further isolate and purify specific molecules. Overall, fractionation syringe filters are a valuable tool in many laboratory applications where the separation and purification of small molecules or biomolecules is required.

What are nylon syringe filters used for?
Nylon syringe filters are used for a variety of laboratory applications, primarily for the filtration of aqueous or organic solutions. These filters are small, disposable devices that fit onto the end of a syringe and are commonly used to remove particles or microorganisms from samples prior to analysis or processing.
Nylon syringe filters are made of a polyamide membrane that is resistant to a range of solvents, making them suitable for filtering both aqueous and organic solutions. They are particularly useful for filtering samples that contain a high concentration of protein or other complex molecules, as they can effectively remove these contaminants while allowing the smaller molecules to pass through.
Some common applications for nylon syringe filters include:
- Sterilization of liquids: Nylon syringe filters can be used to remove bacteria, fungi, and other microorganisms from liquid samples prior to culture or analysis. This is particularly important in microbiology and biotechnology applications, where aseptic techniques are critical to prevent contamination.
- Filtration of cell culture media: Nylon syringe filters are commonly used to filter cell culture media to remove particles or microorganisms that may interfere with cell growth or cause contamination.
- Preparation of samples for HPLC or other analytical techniques: Nylon syringe filters can be used to remove particles or contaminants from samples prior to analysis by high-performance liquid chromatography (HPLC) or other analytical techniques.
- Clarification of solutions: Nylon syringe filters can be used to remove particulate matter or aggregates from solutions, making them clearer and more homogeneous.
Overall, nylon syringe filters are a versatile and essential tool in many laboratory applications where particle or microorganism removal is required. They are available in a range of pore sizes, making them suitable for a variety of sample types and applications.
