Expected output
A clean elution plate of purified RNA with consistent yields across the plate. Because the bead washes are vision-verified, plate-to-plate variability from handling is minimised — the variation you see reflects your samples, not the pipetting.
QC metrics & targets
| Metric | What good looks like |
|---|---|
| Purity | A260/280 ≈ 2.0 |
| Yield CV | Low well-to-well variation |
| Carryover | None — fresh tips per transfer |
Vision verification: every magnet engagement and supernatant removal is confirmed on camera, so an incomplete wash is caught and corrected mid-run rather than showing up as a failed downstream reaction.
