Questão de Química

Considere o seguinte texto: Designed for lower throughput needs, the has a capacity for 32x0.2ml tubes. The wells are arranged in a 4x8 format, allowing the block to accept strips of 8 as well as individual tubes. The block heats and cools very quickly - at rates as fast as 5°C/second. A proprietary algorithm controls block temperature, bringing samples quickly to the target temperature without any over- or under-shoot. Excellent block uniformity ensures consistency sample to sample. Operation of the is controlled from the large, full color, touch screen. Icon driven menus allow users to get running quickly. Programming is extremely 9 simple and includes options for time and temperature increment/decrements, adjustable ramp rates, and an auto pause and restart functions. More than 100 typical programs can be stored in memory and easily recalled. After a run, samples can be held at 4°C. An on-screen report is also available at the completion of a run. The heated lid is self adjusting - the spring loaded platen in the lid comes firmly into contact with the tops of the tubes to prevent sample evaporation and condensation. There are no knobs to turn or levers to adjust. The temperature of the heated lid can be changed or the heating function of the lid may be turned off.
