Guides
All guides Learn the math behind the tools.
Plain-language guides for the calculations every lab runs, each with worked examples and a free calculator.
How to Calculate Molarity
Molarity formula explained for the bench: mass = M × V × MW, worked examples for NaCl, Tris and EDTA, hydrate traps and a free molarity calculator.
C1V1 = C2V2
How to use C1V1 = C2V2 for lab dilutions: step-by-step examples, unit traps, 10X to 1X buffers, and when the equation does not apply.
Serial Dilutions Made Simple
How to plan a serial dilution: dilution factor, 1:10 and 1:2 series tables, CFU back-calculation and pipetting errors that compound.

FAQ
Quick answers
Is everything on NexagenLabs free?
Yes. BenchMate and every companion site are free to use with no login. The books are sold on Amazon; the tools work without them.
Does BenchMate store my data?
No. Calculations run in your browser. The Reagent Log saves recipes only in your own browser storage, never on a server.
Who builds these tools?
Suryaprakash Tripathy, a biotechnology researcher with an M.Sc. from Pondicherry University, national fellowships (ICMR-JRF, DBT-GATB, GATE BT), and research work at IISER Bhopal, IIT Guwahati and ICMR institutes.
Which countries can buy the books?
Every title is on Amazon.com, Amazon.co.uk and Amazon.de, plus other Amazon stores, in Kindle and print editions.
