I.Overview
Ultrafiltration (UF) assumes the core tasks of concentration, purification, buffer replacement and removal of impurities in the separation of biological products, and is especially suitable for the fine treatment of large molecules of biologically active substances (e.g. proteins, vaccines, nucleic acids). UF system is the gold standard of biologics separation, and its irreplaceable core value in biopharmaceuticals lies in: activity preservation, precise separation, and compliance guarantee.
II.Key technology flow
Typical route for downstream purification of monoclonal antibody:
cell culture solution → centrifugation/microfiltration → Protein A chromatography → virus inactivation → **UF/DF (ultrafiltration dialysis)** → purified chromatography → preparation
Plasmid DNA purification process:
bacteriophage lysis → alkaline extraction → ultrafiltration (100 kDa) → affinity chromatography → **tangential flow ultrafiltration (TFF)** → sterile filtration

VI.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
