Sharps refill container with counterbalanced lid is designed for use with Sharpstar In-Room Enclosure System. Design minimizes the potential for overfilling by stopping in the "FULL" position when container reaches maximum capacity. Economical horizontal drop maximizes container volume. Lid design limits accidental or intentional access to container contents and allows visual monitoring of the fill level. Container locks for final disposal.Sharps refill container with counterbalanced lid is designed for use with Sharpstar In-Room Enclosure System.
