Abstract
A dipwell tray for a variety of liquids to be selectively applied by sharp pointed needles to a person's skin. For example, the liquids may be antigens used in skin testing for allergies. The tray has a number of so-called dipwells with co-planar mouths or top openings. In use, the liquids are introduced into the dipwells and the needles are then inserted into the dipwells, making the set-up loaded and ready for the needles to be removed one-by-one with liquid adhering to their sharp points. In order to facilitate the removal of the needles the top openings of the dipwells are provided with oriented needle-receiving pockets whereby the needles in the dipwells will be inclined in a desired oriented direction.
