There is disclosed a thermal cycling cuvette (30, 30a, 30b, 30e, 30f, 30g) constructed with a chamber (32, 32a, 32b, 32c, 32d, 32e, 32f, 32g) having an improved sample fluid thermal time constant. The fluid surface-to-volume ratio, and the cuvette thermal path length and thermal resistance of at least one of the walls that provides a major surface of contact (34, 34a, 34b, 34e, or 164, 34f, or 164f, 34g), are selected to provide such a thermal time constant that is no greater than about 10 seconds for a cuvette volume no greater than about 200 µl. Also included in the cuvette are means (60, 60a, 60b, 60c, 60d, 60e, 60f, 60g) permitting the introduction and removal of liquid into and from the cuvette. A preferred construction permits ready and substantially complete removal of the liquid.
In addition, a method for the amplification of nucleic acid sequences is described.  
                            本发明公开了一种热循环比色皿(30、30a、30b、30e、30f、30g),其腔室(32、32a、32b、32c、32d、32e、32f、32g)具有改进的样品流体热时间常数。流体表面与体积比、比色皿热路径长度以及提供主要接触面的至少一个壁(34、34a、34b、34e 或 164、34f 或 164f、34g)的热阻的选择是为了提供这样的热时间常数,即比色皿体积不大于约 200 µl 时,热时间常数不大于约 10 秒。比色皿中还包括一些装置(60、60a、60b、60c、60d、60e、60f、60g),允许将液体引入比色皿或从比色皿中取出。一种优选的结构允许随时并基本上完全清除液体。
此外,还介绍了一种核酸序列扩增方法。
