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.
