Liquid handling robots and pipetting systems are commonly used in the automation of chemical or biochemical laboratories. The systems automate a diverse range of the workflows used in drug discovery, genomics, proteomics and cell biology research. The containers used in the systems include microplates, tube racks, and reservoirs. The DURAN® microplate holders allow the small 10 or 25 ml GL 25 DURAN® bottles to be used on the decks of many liquid handing robots. DURAN® bottles may be used in stability testing of new drug substances as analogues for the larger DURAN® bottles. The small screw topped DURAN® bottles are a robust, thicker-walled alternative to vials made from glass tubing. The microplate holders are compatible with liquid handling robotic workstations, and automated pipetting system from the major manufacturers such as Tecan, Flow Robotics, Fluent, Eppendorf, Hamilton, Beckman, PerkinElmer, Agilent Technologies, and Thermo Fisher Scientific.
