LOW-MASS SAMPLE BLOCK WITH RAPID RESPONSE TO TEMPERATURE CHANGE

摘要

A sample block for use in the polymerase chain reaction, DNA sequencing, and other procedures that involve the performance of simultaneous reactions in multiple samples with temperature control by heating or cooling elements contacting the bottom surface of the block is improved by the inclusion of h ollows in the block that are positioned to decrease the mass of the block in the immediate vicinity of the wells.
