Abstract
A container with a rotatable lid for reading and handling diagnostic reagents in tape form comprising a body portion, a lid portion, a continuous tape, a reagent-sensing device, and a storage device. The body portion includes an inner and outer surface. The lid portion is attached to the body portion and is adapted to rotate from a closed position to an open position. The continuous tape includes a diagnostic reagent. The reagent-sensing device is attached to either the body portion or the lid portion and adapted to read the diagnostic reagent. The storage device is attached to the body portion that is adapted to hold and dispense an unused portion of the continuous tape. During the rotation of the lid portion, the continuous tape is advanced from the first storage device and is extended over the reagent-sensing device.
