CAV 2000 Series Automatic Viscometer Accessories

High Capacity Sample Track

The High Capacity Sample Track provides for throughput of up to 50 samples per viscometer tube for a total of 100 samples per CAV bath. This “caterpillar track” design is recommended for high-throughput facilities where it is desirable to test more than 13 samples per viscometer tube. With fast-run tubes, the CAV can test 100 samples in under seven hours with a single loading and fully automatic, unattended operation. With regular viscometer tubes, a complete test sequence takes less than a day. Sample Tracks replace the two 13 cup Standard Sample Trays in the basic CAV package.

Pedestal Base

The Pedestal Base permits floor-standing installation of the benchtop CAV at an ideal height for operation. The pedestal will support either one or two CAV bath units along with one service unit. The lightweight aluminum frame is of all-welded construction and is coated with a solvent-resistant epoxy powder-coat finish. The Pedestal Base is supplied with four adjustable leveling feet and all necessary mounting hardware for two bath units. Also included are four 3” (76-mm) diameter locking swivel-type casters that can be installed in place of the standard leveling feet. These casters allow easier movement of the CAV for service and maintenance in tight or otherwise difficult installations.


CAV 2000 Series Enhanced Vapor Reduction System (EVRS)

  • Factory-installed EVRS
  • Upgrade EVRS

Available as a new purchase option or retrofit, the Enhanced Vapor Reduction System (EVRS) is designed to improve the CAV 2000 Series work environment, particularly for used oil applications. The EVRS is recommended for use with toluene solvent at all test temperatures; or with volatile solvents at test temperatures over 80°C. The EVRS is strongly recommended for all applications at test temperatures above 100°C. Both EVRS designs include a transparent hinged cover that mounts to the CAV-2000 frame over the sample trays. The retrofit version, designed for user installation with the bath in place, includes a three-piece clamp-ring to trap vapors below the bath. The new purchase EVRS option includes a vapor reduction plate that is factory-installed under the bath during production.

Multi-Unit Interface Kit

The kit consists of an RS-232 to 485 converter and associated RJ-45 cables. This kit is required for connecting 2, 3, or 4 CAV bath units to a single PC computer. A single CAV bath unit does not require this kit because a single bath unit can be connected to a PC computer via the supplied RS-232 cable. In all cases, however, the PC computer requires at least one available RS-232 serial port to interface to the CAV.

Table-Top Bath-Support Kit

This kit consists of two (2) support bars and mounting hardware for attachment to the Pedestal Base of a single CAV bath unit. These bars add additional support for single bath bench-top installations. The overall footprint width of the bath unit increases from 12” (305 mm) to 18” (457 mm).

Low-Volume Tube Option

(incl. Tube/Vials Adapter Sleeves) The CANNON Low-Volume Tube option permits viscosity testing with as little as 4 mL of sample. Low-volume tubes are most appropriate for applications where sample is expensive or in short supply. Low-volume tubes have a specially designed tip that rests against the bottom of the vial during testing. Rugged aluminum vial adapter sleeves have a spring-loaded base, ensuring correct positioning of the low-volume sample vials. Low-volume tubes have a limited (10-fold) viscosity range and perform with the same accuracy as the standard 100-fold range tubes. The Low-Volume Tube Option includes one low-volume tube, 13 sample adapter sleeves, and a supply of disposable low-volume vials. Additional vial options for the CAV.

Fast-Run Tube(s)

The CANNON Fast-Run Tubes permit more rapid testing of customer materials over a more limited (10-fold) viscosity range. They are most appropriate for high-throughput applications with sample materials that tend to vary slightly in viscosity. Fast-run tubes perform with the same accuracy as the standard 100-fold range tubes, and may be ordered in place of the standard tubes at no additional cost.

Cannon Bath Cooler

The Cannon Bath Cooler (CBC-2K) uses advanced technology to provide thermoelectric cooling power. It is recommended for baths operating below 40°C. Mounted atop the CAV temperature bath, the unit allows bath temperature stability within 10°C of ambient, and enables testing at 20°C in most labs.

Dual Solvent Option

The Dual Solvent Option permits the use of two different solvents for cleaning the viscometer tubes. It is recommended for testing hard-to-clean samples. The user can select either one or two solvents for each sample that is run. Includes the necessary hardware and software and permits the use of customer's non-pressurized solvent container.

High-Temperature Bath Option

The High-Temp Bath Option increases the upper operational temperature range of the CAV-2100® bath unit from 100°C to 150°C. It is recommended for all applications requiring sample testing above the 100°C limit of the standard CAV bath. Includes heat shield, all necessary hardware and 2-½ gallons of 20 cSt silicone bath oil. The Enhanced Vapor Reduction System (EVRS) is recommended for high-temperature operation with this option. Depending on tube range, the Dual Solvent Option may be required. Consult a Cannon Representative before ordering. Ensure temperature compatibility of all solvents in use with the CAV.

Heated Sample Tray Option

The standard CAV bath unit is supplied with two (2) non-heated 13-position sample trays. This option replaces one (1) of the sample trays with one (1) heated sample tray. The temperature of the heated sample tray is variable from ambient to 90°C and is adjusted by controls on the front panel of the CAV. Each heated sample tray has a built-in over-temperature safety limit of approximately 95°C. If both sample trays must be heated, two should be ordered. (Customer to indicate right or left when ordering)

Digital Thermometer (115V)

The Ertco-Hart RTD is a high precision digital thermometer with an accuracy of ± 0.05°C over a range of -183 to +850°C.

Platinum Resistance Probes

Six-inch and twelve-inch probe from Ertco-Hart. Probe includes 6’ lead and probe calibration certificate. Probe Accuracy (includes calibration uncertainty and short-term stability): –196°C ± 0.030°C; 0°C ± 0.030°C; 200°C ± 0.031°C; 420°C ± 0.035°C

Initial added temperature calibration/configuration

Factory-calibration of the CAV-2000 at the customer-requested temperature. This option is helpful for customers who plan to operate the CAV instrument at two or
more pre-set temperatures. Also includes calibration oils and an ASTM thermometer for the calibration temperature.

Heat Exchanger Tube (CAV-2200 only)

All CAV-2200 instruments are shipped with a Heat Exchanger Tube built into the left-hand bath. The Heat Exchanger Tube option provides the same cooling option for the RIGHT-HAND bath for circulation of cooling liquid from the user’s refrigerated chiller. It is recommended when both baths may be operating below 40°C. The Heat Exchanger Tube facilitates bath temperature stability near ambient temperature and may make testing possible at slightly sub-ambient temperatures. The Heat Exchanger Tube must be used with a chiller.

Analog Thermometer for Heated Trays

Analog lab-grade thermometer. For use in heated or high-heat sample trays. Probe protector has convenient pocket clip.

Digital Thermometers for Heated Trays

Digital lab-grade thermometer. For use in heated or high-heat sample trays. Probe protector has convenient pocket clip.

Non-Heated 20-vial Sample Holder

20 cup Sample Holder replaces one 13-cup Standard Sample Tray. The 20-vial holder increases the number of samples that can be tested in the CAV without operator intervention. A total of 40 samples can be loaded for each bath unit. Requires Exhaust Collector Box [P61.3575] for use.

Exhaust Collector Box

One per bath unit, the Exhaust Collector Box is required when ordering the Non-Heated 20-cup Sample Holder.

10-Cup Sample Holder Option

Sample Holder for use with plastic Solo® cups. This option includes the 10-position sample tray and holder inserts. VISCPRO software configuration can easily be changed to accommodate the new tray. Additional vial options for the CAV.

Spare Parts Option

(Indicate tube range and temp when ordering) Two Years Recommended Spare Parts, including pneumatic and electrical components, seals, tubing, ballast, gaskets, o-rings, screws, and more. Customer must specify Tube range.
