LabCalcPro is a precision serial dilution and solution preparation calculator for laboratory professionals. Enter your inputs and get step-by-step, bench-ready protocols instantly. WHAT IT DOES • Advanced serial dilution engine using the standard C1V1 = C2V2 formula • Automatically plans multi-stage serial dilutions for extreme ratios (≥1000×), now supporting up to 3 stages when required • Selects the best pipette from your available set • Rounds volumes to match real pipette resolution • Generates numbered, executable protocol steps • Shows full math derivations for verification NEW IN v1.2 AUTOMATIC 3-STAGE SERIAL DILUTION • Extends the solver beyond 2 stages for extreme dilution ratios • Transparently selects 1-, 2-, or 3-stage plans based on feasibility and pipette comfort • Labels intermediates clearly with concentration units • Documents stage selection reasoning in Show Math SAVED SOLUTES • Save frequently used molecular weights with a custom name • Instantly recall solutes from a searchable picker • Edit or delete saved solutes anytime • Stored locally on your device MOLARITY ↔ MASS • Calculate the mass of solute needed for a target molarity and volume • Or compute resulting molarity from a measured mass • Weighability-aware rounding aligned with analytical balance precision • Volumetric preparation assumption clearly documented in Show Math BENCH MODE Tap the flask icon to enter Bench Mode. The screen stays awake, inputs collapse, and protocol steps display in large text for use directly at the bench. BUILT FOR SCIENTISTS • Supports P10, P20, P200, and P1000 pipettes (customizable) • Handles M, mM, µM, and nM concentrations and L, mL, and µL volumes • Warns when transfer volumes are at pipette limits • Names intermediate solutions with concentrations during serial dilutions • Per-stage math transparency for serial workflows SAVE AND SHARE • Name and save calculations for later reference • Load saved calculations back into the calculator • Copy protocol steps to the clipboard • Export full calculations for sharing TRANSPARENT AND PRIVATE • All calculations run entirely on your device • No account required • No cloud sync, tracking, or ads • Full math shown for every calculation • Deterministic results; identical inputs always produce identical outputs LabCalcPro performs mathematical calculations only. It does not provide medical, clinical, safety, or experimental technique guidance.
