Pressure-temperature boiling point calculator.

Preset list of common chemistry laboratory solvents.

Useful in a research laboratory.

Uses the Clausius-Clapeyron relation to calculate the boiling point of liquids at different pressures, and Trouton's rule to estimate the enthalpy of vaporisation for generic calculations.

Ad free. No special permissions. Lightweight, fast and precise.


1) Select solvent from the menu; select 'generic' if the desired solvent is not available

2) Enter two of the three fields (boiling point, pressure, temperature)

3) Click the relevant button to calculate the missing value

Customised preferences:
* tap the temperature units to toggle between C (Celsius) and F (Fahrenheit)
* tap the pressure units and choose from the options
* theme: if there is a dark/light icon, tapping it will toggle between the two themes. If there is no icon, the theme will match the system theme
