PAC L.P.
Industry’s Fastest, Most Accurate All-In-One Dual Viscometer and Density Meter
Houston, Texas, U.S.A. (January 20, 2022) – Petroleum Analyzer Company, L.P. (PAC) announces the release of OptiMVD. PAC, a global leader in advanced instrumentation for laboratory and process applications, serves the oil & gas industry. OptiMVD is a unique, compact, benchtop solution that measures viscosity and density very fast, without compromising precision and accuracy.
Advanced Viscosity and Density Measurement
For viscosity, OptiMVD complies with ASTM D7945. This method measures the dynamic viscosity of a liquid using PAC’s patented, field-proven technology. The instrument incorporates a capillary tube enclosed horizontally in a thermal block. Thermoelectric coolers keep the block at a constant temperature. During each test, a constant, regulated pressure of compressed air pushes the test specimen across the capillary tube. As the test sample flows past an array of optical detectors, the instrument measures the transit time.
The instrument then converts dynamic viscosity to kinematic viscosity using the density of the liquid. An internal digital density meter, which complies with ASTM D7777, measures this density. By design, the instrument provides exceptionally accurate determination of viscosity and density in petroleum products. In particular, very tight temperature control ensures accurate results between +15°C and +100°C.
Flexible Configurations for Increased Efficiency
Each of the three customizable model configurations loads samples, performs viscosity and density measurement, and cleans the system automatically. In addition, all configurations measure samples with a viscosity range from 1 mm²/sec to 2,000 mm²/sec at 40°C. In a dual-module configuration, OptiMVD measures viscosity at two unique temperatures in a single test run. This takes as little as 10 minutes. It also reports Viscosity Index (VI) in addition to viscosity and density results, all from the same vial. Additionally, the dual configuration allows programming of up to 48 samples at a time.
Simple Operation and User-Friendly Design
In addition to being small, rapid, and highly accurate, OptiMVD is also easy to use. To operate the instrument, users simply load the sample into the heated sample injection port or heated carousels. Then, the 13.3” color touchscreen interface requires just a few interactions to program a test and start a run. Users can also complete calibration and instrument updates quickly. Similarly, data download through the USB ports is quick and simple. With a real cycle time of as little as 10 minutes, OptiMVD is the fastest viscometer/densitometer available today. Moreover, no other comparable instrument in its class matches its precision.
Smart Sample Order
PAC designed every aspect of this product around the end user’s convenience and job to do. For example, its innovative Smart Sample Order feature evaluates the number of samples, the sample order, and the testing temperatures. It also considers any user-defined priority selections to determine the most efficient testing order. As a result, this built-in intelligence reduces total testing time by up to 50% for full carousels running multiple-temperature programs.
Low Total Cost of Ownership
The OptiMVD operates as a fully self-contained system. Therefore, it requires no additional investment in external cooling or heating baths. It also has low consumable requirements, and its design minimizes energy use to support environmental sustainability efforts. Combined with the fast cycle time and low cleaning solvent usage, these features translate into a low total cost of ownership.
Designed with the End User in Mind
“We listened to our customers and watched how they work, and then developed a dual viscometer density meter instrument that delivers high precision and fast analysis times. It is also easy to use, has low cost of ownership and high uptimes, and is packed with labor-saving features in a package that minimizes the use of benchtop real estate. The OptiMVD is designed from the ground up with the end user in mind. It is inherently flexible to meet the needs of laboratories with unique requirements. For example, users can test samples from the same vial at two different temperatures, and they can test samples from either carousel in any order. This ensures a high level of operational efficiency. Combine that with the low total cost of ownership, and the OptiMVD is really unmatched in the industry.”
− Dr. Larry Spino, Group Product Manager at PAC
Designed for the challenges of an industrial lab environment, OptiMVD offers speed, precision, and low cost of ownership. Furthermore, by employing digital automation technologies, it increases test productivity and improves repeatability and reproducibility.
