BioCalc Lab

PCR setup, dilution, molarity & primer analysis — all offline. Built for the bench. No account, no data collection.

BioCalc Lab is a precise, professional bioinformatics calculator designed for molecular biology researchers, students, and lab technicians.

CALCULATORS INCLUDED

PCR Setup Build your PCR reaction table interactively. Add or remove reagents, set stock and final concentrations, choose units from a dropdown, and get an instant pipetting summary with exact µL volumes — including nuclease-free water fill.

Dilution (C1V1 = C2V2) Solve for any of the four variables in the dilution equation. Enter three known values and the result updates instantly, along with a plain-language pipetting instruction.

Molarity Calculate mass, amount (mol), volume, or concentration using molar mass. Supports multiple input paths — enter whichever values you know and the correct result is derived automatically.

Primer Analysis Paste or type any 5'→3' primer sequence. Instantly see:

• Length and base composition (GC / AT counts and GC%)
• Melting temperature via Wallace rule and a simplified nearest-neighbor formula (50 mM Na⁺)
• Four quality checks: GC content, length range, self-complementarity, and 3' hairpin risk
• Reverse complement sequence

DESIGN PHILOSOPHY BioCalc Lab follows a dark lab-aesthetic interface — deep navy background, teal accent readouts, and monospaced numeric displays — so results are easy to read at a glance at the bench.

PRIVACY No account required. No data collected. All calculations happen on-device.
