Descripción

Descripción general

These portable, low-temperature control devices utilize efficient, solid-state, thermoelectric modules to control temperatures from +25 to -20 °C. Unique, dual heat exchanger utilizes either fan forced air or tap water for cooling. Connects to water source using 1/4 in. I.D. tubing. Stirring models have a built-in, adjustable-speed, magnetic stirrer to keep solutions at equilibrium. Useful for reaction kinetics, recrystallizations, cold traps, freezing point determinations, controlling exothermic reactions, condenser for distillations, freezing biological and blood specimens, cold bath or storage chambers. Not CE compliant.
Specifications:

• Rapid cooling to -10 °C (forced air) or -20 °C (tap water), 130 BTU/h initial rate
• Cooling to -40 °C possible by circulating coolant
• Equilibrium reached in 2 to 3 min
• 3 in. diam. aluminum top plate handles solutions up to 200 mL
• 18 gauge aluminum cabinet, 7 W × 5 D × 5 in. H
• Wt = 8 lb

Analog models have adjustable power supply to control cooling.
Digital models have dial-in temperature control with digital setpoint in 1 °C increments, automatic thermistor temperature control (order thermistor sensors separately below), and digital meter readout to 0.1 °C with 0.1 °C accuracy.
