OptiMVD: Viscosity & Density

Fast and Reliable Viscosity Measurement

OptiMVD is a mini viscometer and density meter designed for today’s modern laboratory. Available in five different configurations, all models load the sample, perform viscosity and density measurement, and clean the system automatically. OptiMVD maximizes the power of automation to increase test productivity with significant repeatability and reproducibility improvement.

The dual viscometer/density meter model features two integrated, 24-position autosampler carousels, giving users the ability to program up to 48 tests. The analyzer’s flexibility features allow users to test samples from the same vial at two different temperatures, as well as test samples from either carousel in any chosen order. All models can measure samples with a viscosity range from 1 mm²/sec to 2,000 mm²/sec at 40°C.

Safe and cost-effective to own and operate, the constant pressure viscometer has a precision that meets or exceeds ASTM D445 or its equivalents.

Big Performance in a Small Package

OptiMVD measures viscosity according to ASTM D7945. This method is based upon the Hagen-Poiseuille principle of capillary flow. To determine viscosity with OptiMVD, a sample is drawn from a capped sample vial and then introduced into the measuring cell at a controlled, specified temperature. The measuring cell contains a horizontal capillary tube with optical sensors. A thermal block surrounds the measuring cell.

Density is determined by ASTM D7777 method. The OptiMVD measures density at multiple temperatures yielding precision that is much better than other D7777 density meters.

Benefits:

• Fast – quick testing at 10 mins/sample with maximum cleaning
• Precision – best-in-class with no relative bias to D445 for diesel and lubricant testing
• Flexible – sample from same vial can be used to measure viscosity at same temperature or different temperatures
• Dual viscometers/density meters models for increased sample throughput
• Optimal temperature range for most diesels/lubricants (+15°C to +100°C)
• Full viscosity range without capillary change
• Automatic Viscosity Index (VI) calculation from same vial of sample – no risk of sample contamination or mislabeling leading to inaccurate VI
• Fully automatic self-cleaning
• Small footprint saves valuable lab bench space
• Unique Smart Sampling Ordering automatically optimizes performance and decreases total test time
• Comprehensive Instrument Models: Single Sample Injection Port, 1×24 position carousel, or 2×24 position carousels
