- Molecular biology lab workers making solutions and assay mixes
- Worth noticing
- The dilution tool flags sub-1 µL transfers as hard to pipette and recommends making an intermediate dilution.
Field notes
The molarity form asks for molecular weight, desired concentration, and final volume, then explains the conversion from moles to grams. Buffer setup offers named pKa presets or a custom value, and the accompanying guidance notes that Tris changes with temperature. These details make the calculations easier to interpret at the bench, while the page still advises checking the resulting buffer with a pH meter.
