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 held to hundreds of reference tests against published values. 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 core of Aliquot is a small, framework-free TypeScript engine. There is no server round trip and no network call in the path: you type, and the answer is computed in your own browser before you have finished reading the field label. Four things follow from that.

Full precision, rounded once

Every intermediate value is carried at full precision and rounded only when the number reaches your screen, so what you read is honest to its last significant digit and no step ever inherits another step’s rounding error.

It refuses rather than guesses

Each calculator is a pure function from inputs to a typed result. Given something impossible, a negative volume, a stock weaker than the target you asked for, it returns a specific message naming the problem instead of a number. No code path can quietly hand you something wrong.

One engine, 57 calculators

Dilutions, molarity, buffers, gels, molecular biology, assays and the analytical bench all call the same core, so a correction to the arithmetic is a correction everywhere at once. Several hundred reference tests pin those numbers against published values on every commit.

The shelf is already in it

61 common reagents carry their own molar mass, density and hazard profile, alongside 24 hydrate forms and 11 buffer systems with their pKa and temperature coefficients. You pick a name and the constants arrive with it, so there is nothing to look up mid-prep.

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.

Who builds it

Anushka Rathore

Cofounder and CEO

LMU Munich

I am a Chemistry and Biochemistry student who has spent, and continues to spend, countless hours in university laboratories. After repeatedly dealing with time-consuming calculations, I created Aliquot to make lab work faster, clearer and less stressful, so you can focus more on the science itself.

TUM and LMU Munich, Tools for Humanity

I study physics at TUM and mathematics at LMU, and work on machine learning at Tools for Humanity. The engine behind Aliquot was carved out day and night, with Anushka guiding every decision so it works the way a real chemistry student wants it to. It takes the tedious conversions off your hands and leaves the hard part where it belongs, in the chemistry.
