Syringe Filters

Syringe Filters

Stellar Scientific offers a comprehensive range of syringe filters designed to clarify or sterilize small volumes of media or aqueous solutions. These filters are perfect for GC, HPLC, and other small-volume applications. Explore the options below to find the best fit for your specific requirements.

Why Choose Stellar Scientific Syringe Filters?

Versatile Membrane Options

Our syringe filters are available in a variety of membrane materials and pore densities. Whether you are dealing with aggressive chemicals or delicate biologicals, we provide the specific membrane, such as PES, Nylon, or PTFE, to ensure chemical compatibility and optimal flow rates.

Sterility and Purity Standards

We prioritize the integrity of your samples. Our filters are RNase and DNase-free, guaranteeing contamination-free filtration for sensitive molecular applications. Additionally, our sterile options are individually wrapped, ensuring both sterility and convenience in busy laboratory environments.

Key Benefits of Our Syringe Filter Selection

Precision Clarification & Sterilization

Ideal for small volumes of media or aqueous solutions, these filters utilize manual operation to direct solutions across the membrane face. This enables controlled, efficient filtration, which is essential for preparing samples in research and clinical settings.

Enhanced Industrial and Lab Performance

Syringe filters are widely used in laboratory and industrial settings due to their efficiency and reliability. By utilizing our high-quality filtration products, you achieve:

  • Enhanced Sample Clarity: Removing particulates that can interfere with sensitive readings.

  • Reduced Contamination Risks: Protecting your cultures and chemical reactions from external impurities.

  • Improved Analytical Accuracy: Ensuring better results in critical downstream applications such as chromatography and spectroscopy.

Key Buying Considerations for Syringe Filters

1. Application Specificity

Are you performing biological sample preparation or harsh chemical filtration? Choosing the right membrane (e.g., PES for low protein binding vs. PTFE for chemical resistance) is the first step toward getting the best filtration results.

2. Pore Size Selection for Syringe Filters

Choosing the correct pore size is critical for achieving the desired filtration outcome. 0.22 µm syringe filters are ideal for sterile filtration and bacterial removal in sensitive applications, while 0.45 µm syringe filters are commonly used for sample clarification, removing particulates to protect instruments such as HPLC and GC systems. Selecting the right pore size, along with the appropriate membrane type, helps maintain optimal flow rates, reduces clogging, and ensures reliable performance across a wide range of laboratory applications.

3. Volume and Force

Because these filters rely on manual force, selecting the correct filter diameter ensures you can process your required volume without excessive pressure, maintaining the integrity of the filter housing.

Frequently Asked Questions

Which filters are best for HPLC and GC applications?

For HPLC and GC, we recommend membranes that offer high chemical resistance and low extractables to prevent interference with your chromatograms. PTFE and Nylon are often the preferred choices.

How do individually wrapped filters benefit my workflow?

Individually wrapped filters ensure that each unit remains sterile until the exact moment of use, eliminating the risk of cross-contamination that can occur with bulk-packaged items in a shared lab space.

Are these filters compatible with all standard syringes?

Yes. Our syringe filters feature standard Luer-lock or Luer-slip inlets to ensure a secure, leak-proof connection with virtually all medical and laboratory syringes.

What makes a filter "RNase and DNase-free"?

This means the filters have been tested and certified to be free of enzymes that degrade DNA and RNA. This is critical for any work involving genetic material, ensuring your samples remain intact during the filtration process.
