Simply add 2 ml of sample to the tube, tightly replace the screw cap, and mix the contents by inverting the tube a few times. Place the vials in the DigiPREP CUBE, set to 150 °C, and allow to reflux for 2 hours. Once cooled to room temperature, the samples can be measured using a UV-visible spectrometer.
