With ERAVAP eralytics offers the gold standard for vapor pressure (ASTM D6377) + density (ASTM D4052) testing of crude oil combining ERAVAP with eralytics revolutionary built-in density metre module DENS4052 and with the manual piston-cylinder ERAVAP MPC (ASTM D8009):
eralytics’ innovative temperature-controlled, high-precision density metre module DENS4052 is now available for our vapor pressure tester ERAVAP. With less than 1 kg of weight, it is the lightest and smallest density metre module on the market measuring in full compliance with ASTM D4052 as well as D5002 (r = 0.0001 g/cm³).
This unique feature allows for a simultaneous density and vapor pressure measurement of crude oil and petroleum based products.
Measuring live crudes containing high amounts of volatiles requires the use of a pressurised sampling system. For this task eralytics offers the newly developed manual piston cylinder ERAVAP MPC (ASTM D8009) or a Welker® FPC floating piston cylinder (ASTM D3700). The density metre module DENS4052 is fully compatible with these pressurised filling systems (MPC/FPC), making it uniquely convenient for crude oil testing.
As a higher viscosity significantly delays the formation of a pressure equilibrium, shaking of the measuring cell is mandatory for ASTM D6377. ERAVAP features a superior cell and shaker design, which results not only in a faster measurement but also significantly increases the accuracy and precision.
This was also confirmed by the Canadian Crude Quality Technical Association CCQTA within a recent coordinated study performed by our Canadian partner Parkes Scientific and eralytics.
