Lab Filtration: Samplicity - Performance - No Cross-Contamination

No cross-contamination between filter positions on the Samplicity system. In row 1, filter positions 1, 3, 5, and 7 were used to filter fluorescein-containing samples. In row 2, filter positions 2, 4, 6, and 8 were used to filter the fluorescein-containing samples.*

*Samples containing 0.005% fluorescein in 80:20 (v/v) acetonitrile:water were filtered using every other filter position in the Samplicity system, through 0.45 µm hydrophilic PTFE Millex Samplicity membrane filters. Fluorescence signal was measured by spectrophotometry.
