Calculators for Laboratory & Research Workflows
Open-source, browser-side calculators used by independent labs and research institutions. Nothing is stored, transmitted, or logged — calculations run entirely on your device.
Peptide Reconstitution Calculator
Calculate the exact volume of bacteriostatic water needed to reconstitute a peptide vial to a target concentration.
peptide · mg · IU · mcg
Dilution Calculator (C1V1 = C2V2)
Solve any dilution problem using the standard concentration-volume equation. Supports mg/mL, μg/mL, mM, and percent.
C1V1=C2V2 · stock · working solution
Bac Water Expiration Tracker
Calculate the 28-day post-puncture expiration date for a multi-dose bacteriostatic water vial per USP guidelines.
28-day rule · multi-dose · USP
Cost-Per-Vial Calculator
Compare bulk pricing across pack sizes. See effective cost per vial, per mL, and total savings vs single-vial pricing.
bulk · unit cost · break-even
