Applications

Used to determine the vapour pressure of volatile non‑viscous petroleum products except liquefied petroleum gases.

Details of apparatus

The Vapour pressure bomb is made of brass heavily Chromium plated and consists of air chamber and gasoline chamber of definite dimension and volume ratio. A pressure gauge of required range is fitted above the air chamber. The joints are made leak proof by neoprene washers. The water bath used is of such dimensions that the vapor pressure bomb may be immersed to at least 1 inch above the air chamber and maintained at a constant temperature of 37°C ± 1°C. Bath for single test with FHP Stirrer and with Digital temp. controller and motorized stirrer, with following accessories

1. Vapor Pressure Bomb consisting of One air chamber and One gasoline chamber with cock.
2. NP Pressure Gauge of 0‑15 PSI or 0‑30 PSI or 0‑45 PSI or 0‑100 PSI (Any one)
3. Thermometer IP-23C : (34°C ‑ 42°C X 0.1°C)

Cooling bath At Extra Cost (Refer to optional accessories)

1. To cool the samples to 0°C to 1°C and the liquid chamber to below 5°C. An ice water bath or a refrigerator, with freezer compartment, are suitable. (Deep freezer available at extra cost)
2. Solid carbon dioxide is not a suitable cooling medium due to its solubility in gasolines, which may lead to erroneous results
