The Vapor-Liquid Equilibrium (VLE) Apparatus helps determine the equilibrium relationship between liquid and vapor phases of binary mixtures. It includes a boiling chamber, condenser, and temperature sensors for precise measurements. Students can plot T-x-y and P-x-y diagrams experimentally. Ideal for engineering colleges, polytechnic institutes, and ITIs, this apparatus provides real-world insights into distillation and thermodynamic behavior of mixtures.
