Barnstead Thermolyne® Cimarec® Digital Hot Plates and Stirrers
In development over two years, and representing a significant improvement in safety, performance and value, these redesigned Cimarec® hot plates and hot plate stirrers feature a new digital display, conveying much more information than a simple pilot light. Temperature settings are adjustable in 9°F (5°C) increments “ from ambient plus 41°F to 1004°F (5°C to 540°C), depending on model. Microprocessor-controlled feedback technology maintains consistent, repeatable temperature settings (ideal for labs that perform repetitive procedures) and allows the use of metal vessels or sand baths. Hot Surface Alert¯ safety systems help to protect users from accidental burns. Bright red warning lights signal when heating surface is above 122°F (50°C), and the digital display flashes "HOT" - "OFF" when heating is turned off, until heating surface is below a cool 122°F (50°C).more
The seamless reflective white ceramic top enhances sample visibility and provides an easy-to-clean and alkali / acid resistance surface. Flat top and high-wattage heating elements (wire-wound mica element) combine to provide superior heating transfer and fast time-to-boil. Integral ring-stand holder accommodates 1/2" (1.3cm) diameter support rod. Rugged low-profile cast aluminum body provides stability and durability. The hot plate stirrer includes a more powerful motor, which prevents slow speed lurching¯ and allows operation in high viscosity solutions (400rpm at 350 centepoise). Exclusive StirTrac technology keeps stirring speed at set point regardless of change in viscosity, provides a stir brake that stops the stir bar from any speed, and provides fine control at slow speeds. The stirring range is a wide 50 to 1200rpm.
Three sizes offer flexibility from microscale chemistries to larger vessels. Sample load capacities are 35 lb (15.9kg) on 10 x 10" (25.4 x 25.4cm) models, 25 lb (11.3kg) on 7 x 7" (17.8 x 17.8cm) models and 15 lb (6.8kg) on 4 x 4" (10.2 x 10.2cm) models. All models supplied with detachable cord. Stirring models include 2 x 3/8" (51 x 9.5mm) TFE-coated stir bar; 4 x 4" units include 1" (25.4mm) stir bar.
