Instrument provides a low cost, compact and automated means of testing vapour pressure and results obtained correlate with traditional RVP measurements
Testing the vapour pressure of gasolines and crude oil is important when defining their performance, safety and environmental properties.
It also contributes to the assessment of fuel efficiency and therefore, fuel preservation.
Well-defined volatility characteristics exist enabling producers to manufacture automotive and aviation fuels with known driveability, combustion and efficiency performance.
Keeping up with the latest technology in vapour pressure measurement, John Morris Scientific presents the Setavap 2.
Produced by Stanhope Seta, the new instrument provides a low cost, compact and automated means of testing vapour pressure and results obtained correlate with traditional RVP measurements.
Setavap 2 conforms to international test methods, including ASTM D5191and IP 394 and EN13016-1.
Typically, a test takes less than four minutes, and results do not rely on operator interpretation.
A 3ml sample is injected through a septum into a vacuum chamber, which is controlled at a test temperature of 37.8C.
The pressure inside the chamber is automatically monitored, and once it has stabilised, the resulting vapour pressure is displayed, and the sample discharged.
Setavap 2 is described as easy and fast to use, saving valuable operator time in the laboratory.
It requires only a small sample so there is no unnecessary waste.
All of these benefits are available at a cost which is said to be much less than the price of traditional test equipment, making Setavap 2 the most cost effective way to measure vapour pressure of gasoline and crude oil.
