Fine upstream clarification for difficult, high-particulate liquid samples
The FluidPrep™ 1 µm Upstream Clarification Filter is a single-use fine prefiltration tool for reducing persistent suspended particulates before concentration. Use it when cloudy, clay-like, wastewater-impacted, environmental, or other difficult liquid samples contain fine solids that may interfere with CP Select™ or EasyElute™ workflows.
Because 1 µm filtration may retain cells, protozoa, fungi, organism fragments, biofilm-associated material, particle-associated eDNA/eRNA, or solids-associated targets, users should evaluate target recovery before routine use.
Some complex liquid samples contain fine suspended particles that remain after settling or coarse screening. These particles can contribute to slow flow, premature filter loading, or inconsistent concentration performance.
The FluidPrep™ 1 µm Upstream Clarification Filter supports the Clarify step of the InnovaPrep® 4C Workflow — Characterize → Condition → Clarify → Concentrate — by reducing fine particulate burden before concentration when a less aggressive approach is not sufficient.
Best used when samples contain:
- Persistent fine suspended solids
- Cloudy or clay-like turbidity
- Fine mineral or sediment load
- Wastewater-impacted water with difficult fine particulates
- Environmental water, stormwater, canal water, lagoon water, or receiving water with persistent haze
- Large-volume samples that remain difficult after coarse debris removal
- Samples where direct CP Select™ or EasyElute™ concentration is limited by fine particulate burden
For gross debris, use coarse screening (e.g. 100 µm Mesh Upstream Clarification Filter). For CP Select™ workflows where fouling occurs during concentration, consider CPT-Attached Matrix Prefilters.
