Abstract: A method and apparatus for effecting rapid thermal cycling of samples, by producing a high-velocity air flow through a closed loop flow path, and energizing an electrical heater within the closed loop flow path to heat the air flowing therethrough to a desired temperature. A sample holder is introduced into the closed loop flow path for exposing the sample holder to the high-velocity heated air flowing therethrough for rapidly heating the sample. The sample is rapidly cooled to a desired temperature by de-energizing the electrical heater, and opening an air outlet from the closed loop flow path, while continuing to produce the high-velocity air flow therethrough.

Abstract: An apparatus for controlling the temperature of at least one liquid reaction mixture, the apparatus including (a) at least one reaction vessel having open proximal and distal ends, the at least one reaction vessel including a gas permeable, liquid retaining, barrier positioned at a proximal portion thereof; (b) a pump being in fluid communication with the proximal end of the at least one reaction vessel through the barrier, for generating negative or positive pressure within the at least one reaction vessel, for translocating the at least one liquid reaction mixture through the distal end into and out of the at least one reaction vessel; and (c) a temperature controller being in thermal communication with the at least one reaction vessel for controlling the temperature of the at least one liquid reaction mixture when maintained within the at least one reaction vessel.
