850-DS 8 Channel Filter Plate 0.45um GMF 50/Pk
Whatman SKU: 7707-3300

850-DS Glass Fiber (GF) Filter Plate, 0.45 µm, 50/Pk - 7707-3300

Automated sample preparation routes each aliquot through the plate, producing clarified fractions ready for chromatographic or spectroscopic analysis. The borosilicate glass matrix resists chemical attack across diverse solvents and draws aqueous samples through without preconditioning. Removing particulates at the preparation step resolves the variability that most often disrupts downstream analysis, keeping method performance predictable.

Key Characteristics

• Inorganic construction suits demanding sample-preparation chemistries
• Biologically inert borosilicate fiber with broad chemical compatibility
• Naturally hydrophilic surface wets rapidly with aqueous samples
• Nominal depth retention with high dirt-loading capacity
• Withstands high-temperature pre-conditioning up to 500°C

Filtering every buffer before loading keeps your instrument running clean and uninterrupted. Upstream buffer clarification keeps avoidable particulates out of your flow path while keeping the filtrate analytically clean.

• Column Protection - Particulate removal before injection guards analytical columns and detectors from fouling and stretches maintenance intervals.
• Pharmaceutical Release Testing - Clarified samples meet USP, EP, and JP method requirements for routine QC and batch release workflows.
• Pre-Chromatography Clarification - Clarified aliquots reach the autosampler free of particulates, protecting column lifetime across long runs.
• Analytical Sample Prep - Turbid samples reduce to clean, injection-ready fractions for reproducible chromatographic and spectroscopic assays.
• Automated Dissolution Sampling - Filtered aliquots pulled from dissolution vessels arrive analysis-ready with no manual clarification step.
• High-Throughput Cleanup - Plate-based clarification prepares large analytical batches in parallel and cuts hands-on preparation time per sample.
