About Aliquot

The lab bench, calculated.

Protocols and papers assume you already have the perfect stock. Real benches have whatever is on the shelf. Aliquot turns “what I have” and “what I need” into an exact, safe, copy-pasteable prep protocol in seconds, on your phone, with gloves on.

What it stands for
✓
Correctness is sacred
Every number comes from a pure, deterministic engine with 90+ reference tests. A wrong number is treated as a critical bug, never an acceptable rounding.
⚠
Safety is built in
The relevant hazard rides along with the protocol, from "add acid to water" to GHS notes, so the safe move is the obvious one.
⚡
Answer first, math on tap
You get the result and a step-by-step protocol instantly. Tap "Show work" only when you want to see the derivation.
🔒
Free and private
No account, no ads, no tracking of your inputs. The math runs entirely in your browser, so it works offline at the bench.
How it works

The heart of Aliquot is a small, framework-free TypeScript engine. It carries full precision through every calculation and rounds only at the very end, so what you read is honest to the last significant figure. When an input does not make sense, it returns a clear, specific message instead of a number, so the app can never quietly show you something wrong. Ten calculators (dilution, serial dilution, molarity, percent, acid and base, buffers, agarose and SDS-PAGE gels, RCF, and a unit converter) all share that engine, plus a database of 50+ common reagents that autofills molar masses and densities for you. Every result has a shareable link, a clean printout, and works with no signal.

Aliquot is an educational aid. Always verify against your reagent's Safety Data Sheet and your local lab safety rules. It is not a substitute for an SDS or a lab safety officer.
