Syringe filters are used in analytical chemistry applications to remove particulate contamination prior to analysis. Filtering a sample prior to sample injection into analytical instrumentation will help protect sensitive parts of the instrument from particulate build-up and reduce system downtime. Sample filtration using syringe filters containing 0.45 μm (HPLC) or 0.2 μm (UHPLC) pore size membranes will also extend the life of chromatography columns by preventing particulate from blocking the flow path between the column packing.

Nylon syringe filters can be used for both aqueous and solvent-based sample filtration applications and show excellent chemical compatibility with esters, bases and alcohols. However, it should be noted that nylon syringe filters are not recommended for sample fluids which are strongly acidic.

Pall provides HPLC certification with these products, ensuring that analytical results will not be compromised by extractable filter materials. Pall membranes are tested for compatibility with common HPLC solvents including water, methanol, and acetonitrile, using established HPLC procedures. In addition, to verify low levels of UV-detectable extractables, samples of the syringe filters are evaluated prior to release.

Acrodisc PSF Syringe Filters feature a large effective filtration area (3.9 cm2) for increased sample throughput, ideal for sample volumes of ≤ 150 mL. Pall Acrodisc PSF Syringe Filters are designed to be fully compatible for use with automated robotic handling systems offering reliable and worry-free operation.

Frequently Asked Questions

What is the Pall AP-4438 Acrodisc syringe filter used for?

The Pall AP-4438 Acrodisc syringe filter is used for clarifying liquid samples and removing particulate contamination before laboratory analysis. These filters are commonly used in applications such as HPLC sample preparation, environmental testing, and general laboratory sample cleanup to protect sensitive analytical instruments.

What does the 0.45 µm pore size remove during filtration?

A 0.45 µm pore size is typically used to remove fine particles and suspended solids from liquids. This level of filtration is commonly used for sample clarification before chromatography or other analytical procedures, helping maintain reliable analytical results.

What types of samples are compatible with the nylon membrane?

Nylon membranes are known for their broad chemical compatibility with aqueous solutions, alcohols, and many laboratory solvents, making them suitable for a wide range of analytical and environmental sample preparation tasks.

Why do laboratories choose 25 mm syringe filters?

A 25 mm syringe filter provides a larger filtration surface area, allowing faster flow rates and improved throughput when filtering moderate sample volumes. This size is commonly used when processing samples up to approximately 100–150 mL depending on particulate load and viscosity.

Are Pall Acrodisc syringe filters compatible with standard syringes?

Yes. Pall Acrodisc syringe filters typically feature standard luer-lock or luer-slip connections, allowing them to easily attach to most laboratory syringes for quick and efficient filtration workflows.
