Overview
The ZPOW Powder Dispensing System is a fully enclosed floor standing robot which has been designed to dispense plant sample from input tubes to output well plates. It is controlled from a desktop PC using software written by Labman specifically for this application. The system handles 6ml FluidX input tubes and 96 position well plates via a dual arm Tecan Omni. The robot has a capacity for up to 9 input racks and 12 well plates. Each input rack contains 24 tubes. The system picks each input tube, pierces a small hole in the cap and then dispenses powder using controlled vibration and feedback from a high precision 5 decimal place weigh cell.
