Brookfield DV2Plus Rotational Viscometer

Overview

The Brookfield DV2Plus Rotational Viscometer is a precision-engineered instrument designed for reliable, repeatable measurement of dynamic viscosity across a broad spectrum of Newtonian and non-Newtonian fluids. Based on the well-established Couette principle—where torque required to rotate a spindle at a defined angular velocity within a fluid sample is measured—the DV2Plus delivers quantitative rheological data essential for quality control, formulation development, and process validation in R&D and production environments. Its modular spindle architecture (LV, RV, HA, HB series) enables seamless adaptation from low-viscosity solvents (e.g., solvents, inks, coatings) to highly viscous pastes and slurries (e.g., adhesives, battery slurries, ceramic suspensions), making it suitable for laboratories operating under ISO/IEC 17025, ASTM D2196, ASTM D1084, and USP guidelines.

Key Features

• Precision torque-sensing mechanism with ±1.0% accuracy and ±0.2% repeatability across all speed and spindle combinations
• 7-inch full-color PCAP capacitive touchscreen (800 × 480 resolution) with wide viewing angle and intuitive icon-driven navigation
• 740 discrete speed steps between 0.1 and 200 rpm—enabling fine-grained shear rate control for thixotropic or yield-stress material characterization
• Built-in gel time measurement function using real-time torque monitoring and automatic endpoint detection
• Integrated oscillatory test mode for rapid assessment of viscoelastic onset (e.g., curing, setting, or gelation behavior)
• Digital electronic leveling system—eliminating mechanical bubble-level dependency and reducing setup variability
• Viscosity Test Wizard guiding users through spindle selection, speed recommendation, and measurement protocol based on sample type and expected viscosity range
• Real-time display of viscosity (cP or mPa·s), temperature (°C/°F), % torque, shear rate/stress (calculated), and step program status

Sample Compatibility & Compliance

The DV2Plus accommodates samples ranging from 0.5 mL (with Ultra-Low Volume Adapter ULA) to standard 600-mL sample containers. It supports compliance-critical workflows through optional DV360™ software, which provides full audit trail, user access control, electronic signatures, and 21 CFR Part 11–compliant data integrity features—making it suitable for regulated pharmaceutical, food, and medical device manufacturing environments. All models conform to IEC 61000-6-3 (EMC) and IEC 61010-1 (safety) standards. Calibration verification is supported via NIST-traceable standard oils and Brookfield’s certified calibration services.

Software & Data Management

DV2Plus integrates natively with two complementary software platforms: DV360™ and DV Create™. DV360™ offers advanced statistical analysis, multi-curve overlay, customizable reporting (PDF/CSV/XLSX), and GLP/GMP-aligned documentation—including full electronic record retention and change history tracking. DV Create™ enables creation of up to 25-step automated test methods—including ramped speed profiles, timed hold intervals, and conditional logic—and supports real-time remote monitoring via Bluetooth or USB. Both applications maintain backward compatibility with legacy DV2T file formats and support integration into LIMS and MES systems via standardized data export protocols.

Applications

• QC testing of paints, varnishes, and architectural coatings per ASTM D1200 and ISO 2555
• Rheological profiling of lithium-ion battery cathode/anode slurries during slurry mixing and aging
• Yield stress and thixotropy evaluation of personal care gels, toothpastes, and topical pharmaceuticals
• Process consistency monitoring of food emulsions (mayonnaise, dressings) and dairy products
• Adhesive and sealant formulation development—tracking viscosity drift during solvent evaporation or crosslinking
• Educational labs requiring robust, entry-level rotational viscometry with industrial-grade metrology

FAQ

What spindle configurations are included with each DV2Plus model?

The DV2Plus LV includes four LV-series spindles (LV-1 to LV-4); RV, HA, and HB models ship with six spindles each (RV-1 to RV-6, HA-1 to HA-6, HB-1 to HB-6). ULA adapters are optional accessories.
Is temperature control integrated into the DV2Plus unit?

No—temperature regulation requires external accessories such as Brookfield TC-550AX circulating baths or Peltier-based temperature chambers (e.g., SC4-25). The instrument displays temperature input from compatible probes but does not actively control it.
Can the DV2Plus meet FDA 21 CFR Part 11 requirements out-of-the-box?

Not autonomously—the base instrument records data locally but lacks electronic signature, audit trail, and role-based access controls. These capabilities are enabled only when paired with DV360™ software configured for Part 11 compliance.
How is calibration verified and maintained?

Users perform routine verification using Brookfield-certified viscosity standards (e.g., silicone oils traceable to NIST SRM 2490 series). Annual recalibration by an ISO/IEC 17025-accredited service lab is recommended for GxP-regulated use.
Does the DV2Plus support custom spindle geometries or DIN/ISO-compliant fixtures?

Yes—optional accessories include cone-plate sensors (CP-40, CP-51), vane spindles (VU-1 to VU-4), and DIN-style cylindrical fixtures (SC4-18, SC4-25), enabling alignment with ISO 3219, ISO 6721-10, and DIN 53019 test protocols.
