Syringe hands, robotic

All-purpose hands and syringe hands, available in a variety of designs, are also required elements of a robotic station. Differently sized objects (e.g. sample flasks, test tubes, probes, hold and press push-buttons) call for different types of hand. A syringe hand facilitates the withdrawal of liquids from vessels. Hand design has benefited from innovations devised by academic research groups [10].

The robot replaces its hand by a gripper (GPH), with which it takes the tube containing the sample aliquot and takes it to the dilution unit, where 10 mL of distilled water are added. Next, the tube is taken to the master lab station, where it is first positioned on the tip fitted to the syringe, which adds 1 mL of p-rosaniline, and then to the fixed tip connected to the other syringe, which adds 1 mL of the sodium sulphate solution. Then the tube is kept in the vortex stirrer for 30 s and subsequently returned to the starting point, where it is allowed to stand for 1 h.
