CAV® 4.1 | Single-Bath, Two-Tube, Benchtop Kinematic Viscometer

The CANNON® CAV 4.1 is a fully-automated, single-bath, benchtop viscometer for unattended ASTM D445 testing for kinematic viscosity (KV) of transparent and opaque liquids.

Features and Benefits

D445 Precision in a Modern, Dependable Design

  • Automation replaces labor-intensive manual testing and lowers operator-to-operator variability
  • 0.5 to 10000 mm²/second (cSt) viscosity range in 100-fold increments* (covering the range of five individual manual glass viscometers)
  • Temperature range is 40 to 150 °C  (down to 20 °C with optional TE bath)
  • 28 (2 x 14 position) automated sample capacity allows for unattended operation of up to 24 determinations per hour
  • Easy loading/unloading of samples with removable carousels
  • Colored display lights in bath offer a quick indication of operational status
  • A trusted CANNON viscometer platform offers reliability and dependable support

Compact and Self-Contained with Flexible Configuration

  • Save lab space with 35% smaller footprint than CAV-2000
  • Easy, out-of-the-box setup
  • The onboard computer allows pre-programmed test parameters to be executed without the need for an external PC
  • Included VISCPRO® software allows for the creation of user-defined test procedures and the management and control of up to four instruments from a single PC.
  • View, print, save, and export custom reports

Reduced Consumable Costs

  • Automated washing and drying of sample vials allows for reuse thus decreasing vial purchase/consumption
  • When compared to larger predecessor tubes, next-generation Atlantic-style tubes lower solvent usage and disposal expenses by 50%

Simplified Maintenance and Test Versatility

  • Automated washing and drying replaces manual tube cleaning
  • The modular chassis design allows for simple maintenance access
  • Operators able to replace tubes in minutes
  • High throughput with optional sample preheating up to 135 °C
  • Standard dual-solvent input included
  • Each sample can be tested with its own predefined/user-defined testing method

Common Applications

  • Additive analysis
  • Base stock analysis
  • Crude oil testing
  • Formulated oil analysis
  • Glycols/polyols
  • Hydraulic oil analysis
  • Light and heavy fuel testing
  • Marine fuel testing
  • Waxes/paraffin

*The test temperature and sample type may limit some upper viscosity measurements. Ubbelohde-style tubes are for offered for high melt waxes and volatile compounds that are not pure solvents in 100-fold increments and fast run 10-fold increments from 0.5 to 10000 mm2/second (cSt).
