850-DS 8-Channel Filter Plate 0.45 PTFE 50/Pk
Whatman SKU: 7707-3000

850-DS PTFE Filter Plate, 0.45 µm, 50/Pk - 7707-3000

The multi-well plate processes many vessel samples in a single pass, removing particulates ahead of analytical injection and holding throughput steady. Hydrophobic PTFE repels water while passing gases and solvents freely and filters aggressive organic solvents without breakdown. Consistent parallel clarification holds run-to-run reproducibility steady, so results stay comparable from well to well throughout the sequence.

Key Characteristics

• Hydrophobic membrane repels water for gas, vent, and solvent filtration
• Absolute pore size rating gives consistent results across protocols
• Stable across a wide operating temperature range for demanding methods
• Chemically inert against aggressive solvents, strong acids, and alkalis
• Filters aggressive organic solvents without swelling or breakdown

Handling the harsh solvents your methods demand calls for a filter that holds up to the chemistry, pass after pass. Solvent-stream filtration handles the solvents and reagents your methods rely on from organic mobile-phase prep through reagent clarification.

• High-Throughput Cleanup - Plate-based clarification prepares large analytical batches in parallel and cuts hands-on preparation time per sample.
• Unattended Sampling Runs - Single-use plates paired with automated instruments enable clean, hands-off sample collection through a full test.
• Pharmaceutical Release Testing - Clarified samples meet USP, EP, and JP method requirements for routine QC and batch release workflows.
• Analytical Sample Prep - Turbid samples reduce to clean, injection-ready fractions for reproducible chromatographic and spectroscopic assays.
• Column Protection - Particulate removal before injection guards analytical columns and detectors from fouling and stretches maintenance intervals.
• Pre-Chromatography Clarification - Clarified aliquots reach the autosampler free of particulates, protecting column lifetime across long runs.
