一般描述
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:
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
其他说明
The use of insulated, flat-bottom glassware and aluminum cooling blocks maximizes heat transfer rates from media to cold plate and are highly recommended for use with this equipment.

Evidence suggests that affective disorders are associated with altered thermoregulation, and it has been hypothesized that therapeutic strategies targeting body-to-brain thermosensory systems may be effective for treating depression. Consistent with this hypothesis, a recent randomized, double blind, placebo-controlled clinical trial
