Cannon Instrument Unveils Automated Dual-Bath Kinematic Viscometer

Noria news wires

Cannon Instrument Co. recently released its new automated CAV 4.2 dual-bath kinematic viscometer to enhance productivity, reduce costs and improve data quality for laboratories requiring ASTM D445 precision.

The CAV 4.2, which can operate at any temperature between 15 degrees C and 150 degrees C, has dual independent baths that allow simultaneous testing at two different temperatures. Selective-zone pre-heating heats individual samples to any temperature from ambient to 100 degrees C.

The modular dual-bath design provides easy maintenance access and redundancy for uninterrupted testing. Two independent sample handlers ensure reliable, unattended processing of up to 24 tests per hour within the viscosity range of 0.5 to 10,000 millimeters squared per second.

Multiple pre-defined and user-defined test methods can be conducted in the same sample tray to maximize flexibility and save setup time. Status indicator bath lights provide an indication of operational status, ensuring worry-free operation.

The self-contained, bench-top instrument boasts a smaller footprint than similar dual-bath viscometers to conserve lab space. Installation is simple and requires no external components. Professional installation, data storage and management software, viscometer tubes, standards, and a high-precision digital thermometer are included with each instrument.

An on-board computer and user-friendly touchscreen interface allow a single CAV 4.2 unit to be run without an external PC. For higher throughput labs, a single external PC can manage up to four CAV 4.2 instruments using the accompanying software.

Cost-saving features include a tube design that reduces solvent usage and disposal costs by more than 50 percent. Operators can replace the viscometer tubes in a matter of minutes, eliminating the need to schedule related service calls. Single-point temperature calibration decreases tube recalibration costs and maximizes test flexibility. Automated vial washing and drying helps to reduce vial consumption costs and replaces manual washing to save time.
