Abstract
A wiping cap closure device used for removing the non-calibrated residue fluid attached to the outside surface of a pipette tip during the fluid transfer from a container. The wiping cap is constructed using a conical shaped resilient wiper section extending to a conical tip. The conical shaped wiper section is configured to include at least one helical formed slot extending from said conical tip forming at least one wiping finger. The wiping finger is resiliently held against the outside surface of the pipette tip inserted therethrough during the fluid transfer. The wiping finger provides squeegee like means to remove all of the non-calibrated residue fluid inadvertently attached to the outside surface of the tip as the pipette tip is withdrawn from the container leaving the non-calibrated residue fluid within the container for further evaluations or tests.
