Watch eralytics latest application video and convince yourself how we set the benchmark for Vapor Pressure (ASTM D6377) + Density (ASTM D4052) testing of crude oil combining ERAVAP with eralytics revolutionary density meter module DENS4052 and our new piston cylinder ERAVAP MPC.
2-in-1: Simultaneous vapor pressure and density testing of crude oil
eralytics’ innovative temperature-controlled, high-precision density meter 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 meter 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.

Pressurized sampling system ERAVAP MPC and FPC
According to ASTM D6377-20, measuring live crudes containing high amounts of volatiles requires the use of a pressurized 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 meter module DENS4052 is fully compatible with these pressurized filling systems (MPC/FPC), making it uniquely convenient for crude oil testing. More details on ERAVAP MPC can be found here.
High Performance Cell Shaking Technology
As a higher viscosity significantly delays the formation of a pressure equilibrium, shaking of the measuring cell is mandatory for ASTM D6377. With its overall versatility for crude oil testing, ERAVAP is the only vapor pressure tester on the market providing reliable results for all types of crude oil due to its superior cell and shaker design which results not only in a faster measurement but also significantly increases the accuracy and precision.
This was now also confirmed by ASTM and by the Canadian Crude Quality Technical Association CCQTA. ASTM sent an official email to all members of the subcommittee D02.08 (Volatility), which is in charge of ASTM’s vapor pressure test methods including ASTM D6377.
Moreover, in the latest version of ASTM D6377(20), the standard practice for eralytics Manual Piston Cylinder MPC, ASTM D8009 is accepted as an alternative option along with ASTM D3700 (Floating Piston Cylinder FPC) for using a pressurized filling system.
