1.The valve switches to connect the left- hand syringe to the Tee-junction and probe.

2.The piston of the right-hand syringe remains in the top position to prevent liquid from entering the syringe.

3.The left-hand piston descends to aspirate the specified volume of sample liquid.

Aspirating Small Volumes via the Probe

1.The valve switches to connect the left- hand syringe to the reservoir, thus disconnecting the left-hand syringe from the right syringe.

2.The piston of the left-hand syringe remains in the top position.

3.The right-hand piston descends to aspirate the specified volume of sample.
