PROBLEM TO BE SOLVED : To provide an aerodynamically streamlined enclosure for enhancing probability of meeting requests for accuracy and stability. SOLUTION : A system for preparing a pharmaceutical compound comprises : a scale having a platen configured for placement of an object thereon; a supporting arm comprising a first end coupled to a portion of the scale and a second end extending to a position above the platen of the scale; and an enclosure housing extending from the second end of the supporting arm and configured to house at least one input device. The enclosure housing has a curved front profile to minimize flow disturbance when the system is positioned within a flow hood. SELECTED DRAWING : Figure 14 COPYRIGHT : (C)2019, JPO&INPIT
