Dilute Solution Viscometer (DSV)

High-Precision, High-Accuracy Viscosity Testing Solution at a Competitive Price
The Grace Instrument M2020 Dilute Solution Viscometer (DSV) is the ideal solution for viscosity testing of dissolved polymers. This powerful device features high precision, accuracy, and reliable and reproducible results. Designed to produce extremely fast test results in batch, the M2020 comes standard with full automation at a competitive price.

Basic, Semi-Automation, or Complete Automation Package Options
The Grace Instrument M2020 comes in three convenient options:

• Basic Package – Includes DSV machine with integrated syringe pump, degasser, and PC with advanced software.
• Semi-Automation Package – Includes DSV machine with integrated syringe pump, autosampler, degasser, and PC with advanced software.
• Complete Automation Package – Includes DSV machine with integrated syringe pump, autosampler, scale, degasser, heating stirrer, and PC with advanced software.

Safe Design Features Easy Maintenance and Cleanup
The Grace Instrument M2020 Dilute Solution Viscometer (DSV) is easy to set up, clean, and maintain. Its innovative design features a completely closed solvent system, preventing any splashback from toxic fluids or contamination with the environment. Solvent and polymers are tested at the same time to ensure the best results.

Powerful Viscosity Measurement Capabilities
When used to measure relative viscosity, this device can compare a polymer's current viscosity to a reference solvent, or compare against the viscosity of a different polymer. The M2020 first weighs, then dissolves, the polymer in solvent. Polymer then flows through two capillary tubes, and DP transducers measure the pressure difference between their ends, calculating relative viscosity from the differential pressure ratio. A higher viscosity value corresponds to a polymer with a higher molecular weight, allowing the user to determine if a polymer’s molecular weight has changed due to degradation, manufacturing error, sterilization, and/or other factors.

Advanced Grace Instrument Software Complementary with Each Device
Advanced DSV analysis software is included free with each unit. This interactive, graphics-based software is easy-to-use, intuitive, and compatible with all versions of Windows. Installation is easy. The software is simply installed onto any desktop or laptop and connected to the unit. The unit can then be controlled automatically from the comfort of your own PC.

The Grace Instrument M2020 DSV software allows the user to automatically measure absolute, inherent, intrinsic, relative, or specific viscosity in a single test session, all while simultaneously recording data. A data graph can be auto-generated and exported to spreadsheet format for analysis. Sample preparation and handling can also be automated.

Tests Wide Range of Different Polymers
Several types of polymers can be tested at high temperatures, including, but not limited to, the following: hyaluronic acid (HA), polyamides (nylon), polyethylene terephthalate (PET), polyolefins (including polyethylene (PE) and polypropylene (PP), which are usually harder to test with other viscometers), polyvinyl chloride (PVC), and synthetic rubber (EPDM).

Compact and Easily Movable
This compact unit can be placed on a benchtop and easily moved from lab to lab, maximizing laboratory space.

Powerful Testing Tool with Several Applications
The M2020 is a powerful testing tool, precisely and accurately measuring viscosity for medical, chemical, QC, and many other scientific and/or industrial applications. For example, it can be used for production lot release testing; aging, degradation, material comparison, shelf-life, and sterilization studies; and more.
