The OPTIMA ImmuFill, designed for filling bottles with (ancillary) reagents, dispenses liquids into bottles of varying diameter and depth. Its format can be changed in less than 30 minutes. An integrated robot inserts the bottles together with their caps into the star wheel. Only the robot’s vacuum cup needs to be switched when changing formats, which can be done quickly and easily with a plug-in coupling. In addition, 2-, 4-, 10-, and 100-milliliter bottles can be processed on one wheel.
