How are you using your nylon membrane filter?

Our customers generally fall into 5 categories of nylon membrane filter application

HPLC sample preparation
High-Performance Liquid Chromatography (HPLC) is a critical technique in both analytical and preparative settings. Whatman nylon filters are particularly suited for HPLC sample preparation due to their low extractables and high solvent resistance. They effectively remove particulate contaminants from your samples, ensuring that your chromatographic results are accurate and reproducible. The filters are compatible with a wide range of organic solvents, making them ideal for various HPLC methods.

These filters support ASTM D7303 for the determination of trace elements in gasoline by ICP-MS, where sample clarity is crucial.

Gas filtration
In laboratories and industrial environments dealing with gases, such as those in petroleum and natural gas industries, Whatman nylon membrane filters provide effective particulate removal. Their high mechanical strength makes them durable enough to withstand the pressures often encountered in gas filtration applications.

They are frequently used in gas chromatography (GC) systems to prevent particulate contamination that could damage sensitive equipment or affect the accuracy of results.

Aqueous solution filtration
Nylon membranes are hydrophilic, making them an excellent choice for filtering aqueous solutions. This characteristic is especially beneficial in environmental testing and water quality analysis, where the removal of particulates from water samples is essential.

In environmental labs, these filters are often employed in EPA Method 525.2 for the determination of organic compounds in drinking water. Their efficiency in capturing fine particles ensures the reliability of test results.

Protein filtration and purification
For researchers working in life sciences, particularly in the fields of molecular biology and biochemistry, Whatman nylon filters are ideal for protein filtration and purification tasks. Their low protein binding properties help maintain the integrity of protein samples during filtration, which is critical in proteomics studies.

They are used in various standard operating procedures (SOPs) for protein assays, including Bradford and Lowry methods, where sample purity directly impacts the accuracy of concentration measurements.

Clarification of buffers and reagents
In both academic and industrial labs, the clarification of buffers and reagents is a routine task. Whatman nylon filters offer excellent flow rates and filtration efficiency, making them suitable for the rapid clarification of solutions before use in sensitive assays or experiments.

These filters are often used in the preparation of buffer solutions in pharmaceutical labs, where the removal of particulate matter is critical to avoid interference in drug formulation processes.

Why choose nylon over other membrane filter types?

Nylon is a common membrane filter material, but it might not be right for your application. Here's how it compares to other commonly used membranes like PTFE, PVDF, and cellulose acetate.


Nylon membrane filters

Strengths

  • Nylon filters offer excellent compatibility with a broad range of solvents, including most organic solvents and aqueous solutions. This makes them highly versatile, particularly in applications like HPLC sample preparation and environmental testing.
  • These filters have low levels of extractables, which helps maintain the purity of your samples. This is especially important in analytical applications where contaminants can interfere with results.
  • Nylon membranes are known for their durability and resistance to tearing, making them a reliable choice for high-pressure applications such as gas filtration.

Limitations

  • While their hydrophilic nature is advantageous for filtering aqueous solutions, it can be a drawback in applications requiring hydrophobic membranes, such as filtering non-polar solvents or gases.
  • Nylon has moderate protein binding capacity, which may be a concern in life sciences applications where sample recovery is critical.

PTFE (polytetrafluoroethylene) membrane filters

Strengths

  • PTFE filters are chemically resistant to almost all solvents, acids, and bases, making them ideal for aggressive chemical environments and applications involving strong solvents.
  • These filters are naturally hydrophobic, making them perfect for gas filtration and the filtration of non-polar solvents. They can be made hydrophilic through treatment for specific applications.

Limitations

  • PTFE membranes generally have lower flow rates compared to nylon, which may slow down processes in applications requiring rapid filtration.
  • PTFE filters tend to be more expensive than other membrane types, which could be a consideration for labs with budget constraints.

PVDF (polyvinylidene fluoride) membrane filters

Strengths

  • PVDF membranes are known for their very low protein binding capacity, making them ideal for applications where sample recovery is essential, such as in protein assays and purification.
  • These filters are compatible with a wide range of solvents, including many organic solvents and aqueous solutions.

Limitations

  • Moderate chemical resistance: While PVDF has good chemical resistance, it is not as robust as PTFE, particularly against strong acids and bases.
  • Cost and availability: PVDF membranes are typically more expensive and might not be as readily available as nylon or cellulose acetate filters.

Cellulose acetate membrane filters

Strengths

  • Like PVDF, cellulose acetate membranes have low protein binding properties, making them suitable for biological and clinical applications.
  • These filters offer high flow rates, which is advantageous in applications requiring rapid filtration, such as sterile filtration of aqueous solutions.

Limitations

  • Cellulose acetate is not compatible with many organic solvents and is prone to degradation in acidic or basic conditions, limiting its use in more aggressive chemical environments.
  • These filters are more fragile and prone to tearing compared to nylon and PTFE, which can be a drawback in high-stress applications.

Choosing the right filter for your application

When choosing your membrane filter, remember…

  • If you need a versatile filter with good chemical compatibility and mechanical strength, nylon is an excellent choice, especially for aqueous solutions and general-purpose filtration.
  • For handling aggressive chemicals or filtering gases, PTFE membranes offer unmatched chemical resistance and hydrophobic properties.
  • In protein-sensitive applications where sample recovery is critical, PVDF or cellulose acetate may be the best options due to their low protein binding characteristics.
