The micro-plate centrifuge is a unique mini instantaneous centrifuge which is special designed for the 96-hole micro plates. It can quickly spin down droplets and condensation. It is used before and after thermal cycling to improve PCR yield. Put the micro plate from the slots of the top vertically ( leakage for liquid will be kept in the micro plate under the action of surface tension) , the spin-down work is easily finished. Two operation modes humanized configured – short mix and time setting operation, makes the experiment more convenient and efficient.
