Overview
The Vapor Pressure Analyzer (VPA) measures the vapor pressure of solids, liquids, and oils with exceptional accuracy using the Knudsen Effusion method, a highly sensitive gravimetric technique.
Designed for reliable and precise measurements, the VPA helps researchers understand how materials evaporate and behave under different conditions. This information is critical for product development, formulation, and stability studies across industries such as pharmaceuticals, agriculture, and specialty chemicals.
