LabCalc: a pocket calculator for the lab bench

Field notes

The site groups four bench calculations behind separate browser tools: dilution, antibody preparation, molarity or mass conversion, and centrifuge rpm-to-RCF conversion. Its examples include a 12-well antibody preparation with 10% excess, a 1 M Tris recipe for 250 mL, and a rotor-radius calculation for translating 12,000 rpm into relative centrifugal force. The page also supplies quick references for 1× PBS, 50× TAE, and common antibody dilution ranges.
