The thermal cycler (also known as a thermocycler, PCR machine or DNA amplifier) is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction (PCR). [1] Thermal cyclers may also be used in laboratories to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid ...
Quantitative PCR instruments monitor the progress of PCR, and the nature of amplified products, by measuring fluorescence.. The range of different fluorescent labels that can be monitored, the precision with which they can be measured, and the ability to discriminate signals from different labels, are relevant performance characteristics.
A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold ...

Heinrich Johann Welker (9 September 1912 in Ingolstadt – 25 December 1981 in Erlangen) was a German theoretical and applied physicist who invented the "transistron
It removes heat from the engine exhaust steam to condense it back into water. In the case of the WHE-25 engine in the previous sub-section, of the 146.5 kW of heat energy supplied in the initial steam, 10 kW was converted into electricity. That leaves 146.5 - 10 = 136.5 kW of heat energy to be removed by the condenser.
The company was founded in 1939 by William M. "Bill" Lester (1908-2005) and his first wife, Betty L (Lubarsky). [1] Rapidly establishing itself as a “leading contractor of custom-made parts and products in plastic” [2] Pyro employed the injection molding method for forming plastic shapes, which Lester had perfected in the early 1930s.
