About Us

An open-access, precision biochemical utility engineered to eliminate pipetting errors, unit confusion, and volumetric inaccuracies in modern life-science research workflows.

Our Core Mission & Scientific Vision

In pharmacological screening, molecular biology, and biochemical assays, accurate solution preparation is the cornerstone of reproducibility. A slight mathematical error or misjudged unit conversion can distort dose-response curves ($IC_{50} / EC_{50}$ values), induce unintended vehicle cytotoxicity, or ruin costly research-grade compounds.

Tocris Dilution Calculator was developed to give scientists, laboratory technicians, and academic researchers an instant, distraction-free, and mathematically validated utility for single dilutions ($C_1V_1 = C_2V_2$), dry powder reconstitutions, and multi-well serial dilution series.

Methodology & Rigorous Standards

Our computational framework adheres strictly to international chemical stoichiometry standards and established scientific principles:

Conservation of Mass: All stoichiometric algorithms operate on closed-system mass conservation principles ($C_1V_1 = C_2V_2$).
Standard Molarity & SI Unit Logic: Automatic normalization across all metric orders of magnitude (Molar, millimolar, micromolar, nanomolar, picomolar) and liquid volume scales (Liters, milliliters, microliters, nanoliters).
ACS Reference Formulations: Powder reconstitution math aligns with American Chemical Society (ACS) and National Institute of Standards and Technology (NIST) molecular mass conversion rules.

E-E-A-T Benchmark: All formulas are cross-calibrated against verified pharmacological reference datasets and validated against standard analytical laboratory protocols.

Core Capabilities Built for Bench Work

Single Dilution Solver Solves for any unknown ($V_1$, $C_1$, $V_2$, $C_2$) with live visual feedback on diluent and stock aliquots.

Powder Reconstitution Calculates precise reconstitution solvent volumes from compound mass (mg) and molecular weight ($MW$).

Serial Dilution Generator Builds automated multi-step pipetting tables (2-fold, 5-fold, 10-fold) formatted for 96-well microplates.

Vehicle Safety Guardrails Automatically computes dilution factors to keep organic carriers (DMSO, EtOH) safely below the 0.1% cytotoxicity ceiling.

Maintained by Independent Computational Scientists

This web application is developed and actively maintained by independent computational developers and life-science researchers committed to building high-performance, client-side scientific software. We believe that critical laboratory utilities should be fast, completely free to access, and respectful of researcher privacy—processing 100% of calculations inside your local browser without data harvesting.
