Abstract
In a micro-liquid transfer apparatus including two washing tanks (first washing tanks A and B), operations to transfer a sample are carried out using two pin tools (pin tools A and B) alternately. While one pin tool A is being mounted on a pin tool holder and is being used to transfer a liquid, the other pin tool B is waiting in a state where the lower end portions of their associated pins are immersed in the first washing tank B. While one pin tool A is being mounted on a pin tool holder and is being used to transfer a very small amount of liquid, the lower end portions of the respective pins of the other pin tool are washed, whereby the liquid transfer operations can be made in progress with no interruption and thus the generation of the operation waiting time can be prevented.
