Fully automated sample extraction system

Fully automated sample extraction system has been in operation at the Shanghai CDC.

The main automated operations realized by the system include:

Capping, uncapping, pipetting, dosing, stirring, centrifugation, and filtration. The expected throughput is 96 samples/16 hours.

Main functions:

◆ Capping and Decapping

Equipped with two different capping and uncapping bases, two tubes can be operated at the same time.

To avoid contamination, the caps are used one-to-one with the reagent tubes.

◆ Pipetting and Filling

Equipped with a 5mL pipette, which can be fixed or moved with the liquid level, and 4 syringe pumps of different models.

Stirring

Magnetic stirring mode, one batch can handle 30 50mL centrifuge tubes at the same time, stirring speed and time can be set freely.

◆Centrifugation

The centrifuge has been deeply modified to adapt to robotic arm operation and run control.

One batch can process 6 50mL centrifuge tubes at the same time. The maximum speed is 9000rpm, and the speed and time of centrifugation can be set freely.

◆ Temperature Control

The sample table is of sunken design, and the temperature is set at 4±3℃ according to customer's needs.

◆Filtration

Positive pressure is used to make the liquid pass through the filter and enter into the empty sample tube, and other filter membranes can be replaced according to the needs.
