Buffercast: Buffer Recipes

From recipe to bench record, Buffercast plans lab buffers the way they are actually made: formulation, execution, and the evidence trail, all on this device. FORMULATION CONTROL - Maintain multiple named formulations with revisions, intended use, target volume, pH, tolerance, and working temperature - Model solid-molar, stock-molar, mass-per-volume, weight/volume-percent, and volume/volume-percent components - Record lot identity, addition sequence, molecular mass, source concentration, and target concentration - Use an optional conjugate-pair planning estimate with explicit acid and base roles - Fingerprint the complete formulation record with SHA-256 TRANSPARENT PLANNING - Review every planned quantity with its equation and units - Inspect the idealized Henderson-Hasselbalch ratio used for a conjugate pair - Surface missing lots, invalid inputs, liquid-volume overruns, low…
