The stirring speed for this instrument is variable continuously from 0 to 300 RPM using a 2" stir bar in an aqueous solution. It can vary from that figure depending on the viscosity of the solution and the size of the stir bar. The maximum RPM under a no-load condition is 500 RPM.

Allgemeine Beschreibung
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:
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.
Specifications:
- Rapid cooling to -10 °C (forced air) or -20 °C (tap water), 130 BTU/h initial rate
