Cellulose acetate syringe filters are hydrophilic membrane filters designed for laboratory filtration of aqueous and biological samples. They are widely used for sample clarification and sterile filtration due to their low protein binding and consistent filtration performance.

What Are Cellulose Acetate Syringe Filters?

A cellulose acetate (CA) syringe filter consists of a medical-grade polypropylene housing combined with a hydrophilic cellulose acetate membrane. As liquid is pushed through the filter using a syringe, particles and contaminants larger than the membrane pore size are retained, producing a clean and consistent filtrate.

Because of their low protein adsorption characteristics, CA syringe filters are commonly selected for biological, clinical, and analytical laboratory applications.

Key Features

  • Hydrophilic Cellulose Acetate Membrane: Suitable for direct filtration of aqueous solutions.
  • Low Protein Binding: Minimizes sample loss and preserves sensitive biomolecules.
  • Multiple Pore Sizes: 0.1 μm, 0.22 μm, 0.45 μm, 0.8 μm, 1.0 μm, 3.0 μm, and 5.0 μm options.
  • Various Diameters: Available in 4 mm, 13 mm, 25 mm, 33 mm, and 50 mm.
  • Sterile and Non-Sterile Versions: Compatible with a wide range of laboratory workflows.
  • Standard Luer Connections: Compatible with common laboratory syringes.

Applications

  • Biological sample preparation and clarification
  • Aqueous solution filtration
  • HPLC and analytical sample pretreatment
  • Environmental and water sample filtration
  • Clinical and biochemical laboratory workflows

Frequently Asked Questions

What are cellulose acetate syringe filters used for?

They are used to clarify and sterile-filter aqueous and biological liquid samples in laboratory environments, especially when low protein binding is required.

Why choose cellulose acetate over other membrane materials?

Cellulose acetate membranes are hydrophilic and exhibit low protein adsorption, helping preserve sensitive biomolecules and improve sample recovery.

Which pore size should I select?

A 0.22 μm pore size is commonly used for sterile filtration, while 0.45 μm is suitable for general particulate removal. Final selection should be based on application requirements.

Are these syringe filters sterile?

Both sterile and non-sterile cellulose acetate syringe filter options are available depending on laboratory needs.
