Portable system for freezing of embryos based on the use of Peltier cell

摘要

b "portable system for freezing of embryos based on the use of cell Peltier" d , developed for freezing embryos of bovine species and automatic equ00b3inas,Being the instrument of field, characterized by controlling the temperature inside a cooling chamber (8) by executing functions of increase and decrease of temperature gradients.As well as to stabilize it at a desired temperature within the range of + 40,0u00b0c - 40,0u00b0c.Plate composed of microprocessor (1), a communication interface circuits, composed of a / D converters (f) and D / a (3), a plate with a current source (4),Responsible for power control in a Peltier cell (6), where it is located in the cooling chamber (8) of the embryos.
