Laboratory sample preparation and filtration
Single-use filter devices for rapid clarification, analytical sample preparation, sterile filtration and venting of small liquid or gas volumes.
Membrane, rating, diameter and sterile-condition combinations must be confirmed for the sample and intended use
Basic information
Syringe filters combine a membrane or depth medium with a compact molded housing and luer-style connections. They provide a quick way to remove particles before HPLC, UHPLC, ion chromatography or other instrumental analysis, and selected configurations support sterile filtration or gas venting.
A broad membrane and depth-media portfolio for analytical sample preparation, clarification, prefiltration and gas venting.
Rating portfolio 0.2-200 µm
Selected membrane, diameter and pore-rating combinations supplied for compatible low-volume sterile-filtration workflows.
Common sterile ratings 0.2 / 0.22 / 0.45 µm
Membrane and device selection
Selection should begin with sample chemistry and analytical objective, then consider membrane binding, extractables, pore rating, diameter, effective area, hold-up volume, housing material, pressure limit and sterility. Larger diameters generally provide more area and capacity, while smaller devices can reduce product loss in limited samples.
End-user applications
Select membrane, rating, diameter and sterile condition around the sample chemistry, particulate load and downstream method.
Removal of particulates before HPLC, UHPLC, LC-MS, ICP or dissolution testing.
Clarification of buffers, reagents, culture media and biological samples.
Sterile filtration of compatible low-volume aqueous solutions.
Venting or filtration of air and gases with hydrophobic media.
Prefiltration using glass-fiber or polypropylene depth media.
Small-volume process development, sampling and quality-control workflows.
Quotation preparation
A complete RFQ should identify the membrane, rating, device diameter, hold-up target, connection, sterility and documentation requirements for technical review.
Provide solvent system, pH, target analyte, protein content and particulate load.
State clarification, analytical protection, sterile filtration, venting or prefiltration.
Specify membrane, rating, diameter, area, hold-up target and housing compatibility.
Confirm inlet and outlet form, manual or automated use, and maximum pressure.
Select sterile or non-sterile supply, individual packaging, lot testing and certificate needs.
Configuration matrix
Configuration note. Not every membrane, pore rating, diameter and sterile condition is available in every combination. A 0.2 or 0.22 µm label alone does not establish sterilizing-grade performance without the relevant validation claim.
