Dropper system with pre-positioned wiper

Abstract

A dropper system comprises a bulb having a body, a collar, and a flange. The body of the bulb comprises a closed end, an open end opposing the closed end, and a cavity extending between the closed end and the open end. The collar extends axially from the open end of the body and comprises a pipette coupling member that is recessed into an inner surface of the collar. The pipette coupling member is configured to retain at least a portion of a pipette proximate the cavity of the body. The inner surface is tapered between the pipette coupling member and an opening of the collar. The flange extends radially from an outer surface of the collar and comprises a lip protruding axially about a perimeter of the flange such that an annular recess is formed between the outer surface of the collar and the lip.
