Description:
The Cannon CT-1000 High Temperature Bath maintains the accurate control required by ASTM D445 for kinematic viscosity measurements with glass capillary viscometers. Up to seven glass capillary viscometers (in holders) can be placed in the bath. The top cover contains seven round holes 51 mm (2 inches) in diameter. CT-1000HT can achieve a temperature range from 25°C to 200°C. The temperature selection dial includes quick-set options for 25, 40, 60, 80, 100, 135, 150, 165, 185, and 200°C Temperatures from 150 to 200°C can be controlled to 0.03°C (more precise than required by ASTM D 445 for high temperature viscometry). After selection of the temperature, the bath will equilibrate within a fraction of one degree of the desired temperature. A fine tuning control then allows temperature adjustment to within 0.01°C of the target temperature. By switching to the "variable" setting on the front panel, any temperature within the operating range can be obtained. The bath chamber is a cylindrical clear Pyrex® vessel 300 mm (12 inches) in diameter x 300 mm (12 inches) high. A stainless steel baffle coated with white PTFE is located in the center of the bath to provide a good background for viewing viscometers. Two fluorescent lamps illuminate the interior of the bath brightly and uniformly, without glare. Two heating elements inside the bath rapidly heat the bath medium to any temperature within the bath range. A stainless steel cooling coil is also incorporated. When connected to tap water or a recirculating water chiller, the cooling coil allows operation at temperatures slightly above or below ambient. Use the CBC-100 Bath Cooler to control temperature down to 15 degrees Celsius below ambient. A solid-state control circuit equipped with a stainless steel-encased thermistor provides proportional control of temperature. A motor-driven stirrer ensures a uniform temperature throughout the bath. All wetted parts of the bath are made of stainless steel, glass, or PTFE®. The bath housing is fabricated from heavy aluminum and coated with a corrosion-resistant epoxy finish. Viscometers, holders, bath oil, and thermometers must be purchased separately. 17 Liter bath capacity. Shipping weight: 123 Lbs.
