Minivap VPXpert Vapor Pressure Analyzer

Analyzer of the vapor pressure of gasoline, gasoline oxygenate blends and crude oil for all vapor pressure standards

Category:
  1. General Details

    The 3rd generation vapor pressure tester for the automatic determination of the vapor pressure of gasoline, gasoline oxygenate blends and crude oil for all vapor pressure standards. Incorporating the Grabner triple expansion method and the US EPA reference method for the determination of vapor pressure, the instrument is designed for significantly improved precision, reliability and performance. Made by experts for expert testing, the ergonomically designed analyzer offers unmatched versatility: The instrument incorporates features for V/L ratio determination (ASTM D5188), for crude oil (ASTM D6377) and R&D applications and volatility studies over an unprecedented temperature range (0-120°C). The innovative Sampling Pro™ technology minimizes the risk of cross contamination between different sample types.
