Free browser-based lab arithmetic for concentration and aliquot volume. Separate mass and labeled IU, inspect worked examples, and copy or print a calculation. No account required.


We built a small laboratory-arithmetic companion at BioCura Labs, the research-materials supplier behind this tool. It keeps total amount and final volume explicit, separates mass from labeled activity, and refuses invalid inputs instead of leaving old results on screen. Worked examples, a shareable calculation link and a one-page report make the arithmetic easier to review. We welcome feedback on unit clarity and browser behavior. This is calculation software; it does not select a protocol or establish sample properties.
