PCR Thermal cycler sample block with function of selective temperature control for PCR

摘要

The present invention relates to a PCR block capable of independent temperature control, and more specifically, the upper and lower ends of a plurality of heating chambers constituting an array can be selectively energized by dividing each of the upper and lower ends of the heating chambers into columns and rows, and temperature is matched one-to-one to the heating chamber. Since the measurement sensor is provided, each heating chamber can be accurately controlled independently, and the conventional thermal chamber can be replaced only by combining the heating chamber coated with a heating element between the upper board and the lower board in the form of a printed circuit board. , The structure is simple and the manufacturing cost is reduced, and the heating chamber having the shape of the upper beam is directly heated to allow direct heat conduction to the tube body close to the inner side, and the heating and cooling can be performed quickly due to the small heat capacity of the heating chamber. It is an object of the present invention to provide a temperature circulator for PCR having a plurality of single thermal chambers that can shorten the temperature cycling time.
