The Phase OptiMVD AS2 Dual Carousel Viscometer and Density Meter (OptiMVD-AS2) is an automated, high-throughput system with two 24-position carousels, two viscometers and two density meters for diesel and lubricant testing. It measures viscosity from 1 mm²/s to 2,000 mm²/s at 40°C and density from 0.5 g/cm³ to 2 g/cm³ across a sample temperature range of +15°C to +100°C.
Key Features
- High-throughput AS2 configuration, combining two 24-position carousels with two viscometers and two density meters for up to 48 programmed tests
- Same-vial testing at two temperatures, allowing the dual-meter system to analyse one sample under two temperature conditions
- Automatic viscosity index calculation, using measurements from the same sample vial to reduce contamination and identification risks
- Smart Sample Ordering, evaluating samples, temperatures and priorities to reduce total testing time by 20% to 50% or more under suitable multi-temperature workloads
- Automated sample processing, with sample loading, viscosity and density measurement, heating, cleaning and drying controlled by the instrument
- Full viscosity range without capillary changes, covering 1 mm²/s to 2,000 mm²/s at 40°C
- Broad temperature control, using an internal Peltier system across a sample range of +15°C to +100°C
- Dedicated measurement technologies, with a constant-pressure capillary for viscosity and an oscillating U-tube for density
- Fast automated testing, with analysis time varying by required precision and approximately 10 minutes per sample with extensive cleaning
- Standards-based analysis, supporting ASTM D7945 and ISO 18335 viscosity testing and ASTM D7777 density testing
- Large touchscreen interface, featuring a 13.3-inch colour display, virtual keyboard and 1920 x 1080 resolution
- Flexible laboratory connectivity, with USB, Ethernet, RS-232, automatic LIMS transfer and data export for Excel
Benefits
- Processes up to 48 programmed tests to support higher daily sample throughput with fewer manual loading cycles.
- Uses the same vial for two-temperature measurements and viscosity index calculation, helping reduce sample handling and identification errors.
- Shortens complex testing sequences by automatically arranging samples according to temperatures and operator priorities.
- Accommodates a broad viscosity range without requiring capillary changes between different sample types.
- Reduces routine operator involvement through automated loading, measurement, heating, cleaning and drying.
- Supports traceable laboratory workflows through result storage, LIMS communication and Excel-compatible data export.
