RayCrest Lab Calculator is a bench-side calculator for researchers, students, and lab teams who prepare buffers, solutions, dilutions, and timed protocols. Turn buffer parameters into practical prep guidance. Choose a buffer, set target pH, concentration, volume, temperature, and preparation preference, then generate steps for weighing solids, mixing stocks, or titration. Built-in tools include: - Buffer charts and filterable buffer selection - Henderson-Hasselbalch buffer recipes - Stock mixing and titration guidance - Solution and dilution calculations - Mass/volume, mole/volume, and molarity conversions - Protocol timers for repeated lab steps - Optional compound lookup and manual molecular weight entry - Saved recipes, compounds, and preferences Designed for iPhone and iPad, RayCrest Lab Calculator keeps everyday lab math organized in one place. Use quick calculations at the bench on iPhone, or the larger iPad layout for planning recipes, viewing buffer ranges, and checking multiple values. Local by default: Saved recipes, compounds, and preferences are stored locally on your device. The app does not include analytics, advertising SDKs, or tracking frameworks. Manual calculators work without online lookup; optional compound search may use network access only when you choose to look up compound information. RayCrest Lab Calculator is a calculation aid for research and educational lab workflows. Always verify units, pH, reagent compatibility, and safety requirements before preparing reagents.
