Problem Statement

In a laboratory, chemists often need to make multiple samples of solutions and thus require the pipetting of a common solution many times. However, this can become very strenuous and repetitive to the chemist as well as lead to the propagation of human error. Automated pipetting solves these problems and allows for more precise results than manual pipetting while freeing personnel from the bench.
