Dual Bath Kinematic Viscometer

ASTM D445 Viscometer: Revolutionizing Viscosity Measurements with Viscol-20AS

The Viscol-20AS Dual-Bath Kinematic Viscometer is a state-of-the-art, fully automated viscometer designed for precise kinematic viscosity measurements of Newtonian fluids. Engineered to meet and exceed global standards, including ASTM D445, ISO 3104, IP 71, GB/T 265, and JIS K 2283, this viscometer is an indispensable tool for laboratories and industries requiring accurate viscosity analysis.

Dual-Bath System for Enhanced Efficiency

One of the standout features of the Viscol-20AS is its dual-bath configuration, allowing simultaneous viscosity measurements at two different temperatures—typically at 40°C and 100°C. Each bath is equipped with a 23-position autosampler, enabling high-throughput analysis and reducing the time required for sequential measurements. This design is particularly beneficial for applications in the petroleum industry, where both low and high-temperature viscosity data are essential.

Operational Advantages

The Viscol-20AS is engineered for 24/7 non-stop operation, making it an ideal choice for high-throughput environments and laboratories that demand a steady stream of kinematic viscosity measurements. The autosampler’s innovative design allows for the integration of new samples without interrupting the ongoing tests. The unique design of the autosamplers allows users to add new samples without interrupting ongoing operations, facilitating non-stop, unattended measurements.

Advanced Automation and User-Friendly Interface

The Viscol-20AS offers fully automated operation, minimizing manual intervention and ensuring consistent, repeatable results. The system features a user-friendly touchscreen interface that simplifies navigation and control, making it accessible even to operators with minimal training. Automation extends to the cleaning process as well; the viscometer is equipped with a dual-solvent washing system that effectively cleans and dries the viscometer tubes after each measurement, preventing cross-contamination and ensuring the integrity of subsequent tests.

Precision Temperature Control

Temperature stability is crucial in viscosity measurements, as even minor fluctuations can significantly impact results. The Viscol-20AS excels in this area by offering precise temperature control with a sensitivity of 0.001°C, surpassing the ASTM D445 requirement of 0.02°C up to 100°C. This high level of control ensures that measurements are accurate and reliable across a wide temperature range of 15°C to 150°C.

Wide-Range Capillary Tubes

To accommodate a broad spectrum of viscosity measurements without the need for frequent tube changes, the Viscol-20AS utilizes wide-range Ubbelohde-type viscometer tubes with folds ranging from 170 to 225. These specially designed tubes require only 10-15 mL of sample and up to 15 mL of solvent for the cleaning process, optimizing both efficiency and resource utilization.

User-Friendly Interface

The Viscol-20AS, an Automatic kinematic viscometer, is crafted as a stand-alone unit featuring a 12” wide-screen touch panel PC. This design eliminates the necessity for an external PC, thereby streamlining operations. The software is thoughtfully partitioned into two sections for independent management of each viscometer bath.

Viscosoft Control and Data Evaluation Software

Equipped with Viscosoft software, the Viscol-20AS offers centralized control and precision data evaluation. Users can effortlessly oversee multiple units, incorporate samples into the analysis queue, and generate ready-to-print viscosity reports, all backed by an unlimited results database.

Contactless Detection Technology

A notable innovation is the contactless detection block, ensuring precise measurements of both light and dark samples without direct contact with samples, which is crucial when converting kinematic viscosity to dynamic viscosity. In this design, the sensors are located outside the viscometer, minimizing the risk of damage from wear metals and other contaminants, a common concern when discussing dynamic viscosity vs kinematic viscosity.

Unique Cleaning Technology

The Viscol-20AS addresses the cleaning challenge with its dual-solvent washing technology, enhancing vial washing procedures. The dual-solvent washing system not only ensures thorough cleaning but also minimizes solvent usage, reflecting a commitment to environmental responsibility. Additionally, the sealed washing feature prevents solvent vapours from escaping, maintaining a safe laboratory environment. This cleaning process also includes washing and drying the sample nozzle after each use to avoid cross-contamination.

Easy Tube Replacement

Viscol Series viscometers feature wide-range viscometer tubes (170 to 225 Fold), ensuring accurate kinematic viscosity measurements. In the case of tube replacement requirements, it is very simple for users to replace their viscometer tubes without any service requirement. Tubes are connected with plug-in connections to the system. Users disconnect the connections and remove the viscometer tube. After the tube replacement, the connections should be plugged back into the new tube and the unit is ready to go.

Automatic Calibration

While all Viscol Series viscometers undergo factory calibration, users have the flexibility for automatic recalibration through the menu using standards, such as reference material, ensuring ongoing accuracy in viscosity measurements.

The Viscol-20AS dual-bath kinematic viscometer redefines viscosity measurements with its adherence to test methods and kinematic viscosity analysis. Viscol-20AS dual-bath system, advanced automation, precise temperature control, and compliance with international standards make it an invaluable asset for laboratories and industries demanding accurate and efficient viscosity analysis.  Its automated features, precise controls, and user-friendly design, along with affordable pricing, make it a standout choice for industries seeking reliable and efficient viscosity analysis.
