Calculators

This calculator determines the concentration of protein in a solution using spectrophotometric absorbance measurements. It applies the Beer-Lambert Law to calculate the concentration based on absorbance, path length, and molar absorptivity coefficient.

Calculates pressure, volume, number of moles, or temperature using the Ideal Gas Law: PV = nRT. This calculator assumes ideal gas behavior.

Calculates the compressibility factor (Z) for a real gas, indicating its deviation from ideal gas behavior.

Convert between PPM and other concentration units like percentage, ppb, ppt, mg/kg, and mg/L (for solutions with a density close to 1 g/mL).

This calculator determines the molecular SO2 content in homemade wines, helping winemakers achieve optimal wine preservation. It supports different wine types and pH levels.

This calculator helps winemakers determine the molecular SO2 content for wine stability and provides sulfite addition recommendations based on wine type and pH levels.

Calculates the relationship between pressure, volume, and temperature of a gas using the combined gas law: (P1 * V1) / T1 = (P2 * V2) / T2. This calculator allows you to solve for any one of these variables, given the others.

Calculates the melting point of a substance based on the provided pressure. This calculator uses a simplified model and is most accurate for substances with well-defined melting points. Note: This calculator provides estimations and should not be used for critical applications.

Convert moles of a substance to its mass using the molar mass of the substance.

Calculates the total pressure of a gas mixture using Dalton's Law of Partial Pressures.
