- The dilution tools account for a minimum pipetting volume and can add an intermediate dilution when a direct transfer would be too small.
Field notes
The calculator inputs reflect practical bench details, including a minimum pipetting volume and an optional intermediate dilution rather than assuming every transfer is feasible. The PCR mixer gives handling guidance—water first, enzyme last, and keep the mix on ice—and its example is a 25 µL reaction scaled to 12 reactions with 10% extra. Plate-layout links specify 6- to 384-well formats and offer spreadsheet copying.
