Syringe Filter

Syringe filter specification

PVDF (Hydrophilic/Hydrophobic) syringe filters

Superior membrane quality for HPLC. Hydrophilic PVDF syringe filters do not require pre-wetting for use with aqueous samples. Hydrophobic PVDF filters require pre-wetting with an alcohol before use with aqueous samples.

• Low non-specific binding with exceptional chemical resistance

• Hydrophilic membrane provides excellent flow rates and low binding coefficients

• Certified for chromatographic performance

• Compatible with a wide range of aqueous and organic-based sample environments

• Recommended for HPLC and UHPLC  PVDF syringe filters have a well defined pore structure, giving effective retention of particles without excessive pore blockage. Compatible with aqueous and most organic solvents. They are excellent general filters for HPLC andorganic solvent sample clean up.

Application

• HPLC and organic solvent sample preparation and clean up

• Protein based samples with high non-specific binding

• Environmental water samples

Specifications

Regenerated cellulose(RC) syringe filters

Superior chemical resistance, optimized for biological sample recoveries.

• Hydrophilic membrane provides excellent flow rates and extremely low binding coefficients

• Superior choice for biological assays, gel capsule dissolution testing, protein sample matrixes

• Compatible with a wide range of aqueous and organic-based sample environments

• Recommended for reverse phase and normal phase HPLC

Regenerated cellulose syringe filters are ideally suited for almost any laboratory procedure, from HPLC sample preparation to dissolution sample testing. Regenerated cellulose possesses superior chemical resistance in either aqueous or organic-based sample environments. It’s extremely low biological-based binding coefficient is ideally suited for maximum sample recoveries of biological-based assays.

Regenerated cellulose contains no binders, surfactants or wetting agents to assure minimal extractables in analytical procedures.

Application

• HPLC and organic solvent sample preparation and clean up

• Dissolution sample analysis, especially high-binding tablets or capsules

• Protein-based samples with high non- specific binding

• Sample analysis which require maximum recoveries

• Analysis requiring low non-specific binding over a wide pH range

Specifications

Specifications

PTFE (Hydrophobic and Hydrophilic) syringe filters

• Excellent chemical resistance for use with organic matrices

• Excellent flow rates and high loading capacities

• Exceptional temperature stability

• Organic solvent recommended

• Hydrophilic PTFE can be used for the same application but no pre-wetting of the membrane is required

PTFE syringe filters are applicable for filtration of gaseous or organic solvent-based samples.Both membrane types exhibits broad chemical resistance and unsurpassed temperature stability to address aggressive sample matrixes and extreme temperature situations. The hydrophobic PTFE filter can be utilized as a moisture barrier in venting applications. PTFE hydrophobic membranes require pre-treatment with alcohol before being suitable for aqueous or high aqueous/organic samples. Do not use directly with aqueous solutions.

Applications

• HPLC and organic solvent sample preparation and clean up

• Dissolution sample analysis

• General sample preparation prior to analytical analysis

• Elevated temperature samples, caustic or acidic solutions

Specifications
