An apparatus for heating samples of biological material contained individually on a plurality of fixtures contained on a centrifuge. A flash tube is located adjacent to the centrifuge to convert electrical energy from a capacitor into heat as the samples of biological material go past the flash tube. A trigger signal is used to cause the capacitor to discharge as the biological material moves past the flash tube. Circuitry is used to control the amount the capacitor is charged by using a fixed number of pulses having a controlled amplitude and to prevent charging of the capacitor when the capacitor is discharged. This causes the flash tube to accurately heat the samples of biological material to a predetermined temperature prior to analysis.
