Abstract

A quantitative sample transfer device for receiving and holding a sample while it is weighed and for transferring the weighed sample material into a flask without losing any sample, the quantitative sample transfer device having a hollow central body segment with a flat bottom surface, a first hollow neck at one end of the central body, a second hollow neck at the opposite end of the central body, a removable first cap for occluding the first hollow neck, a removable second cap for occluding the second hollow neck, an opening in the central body for introducing a sample into the body, a lid permanently attachable to the body segment over the opening that remains permanently closed once closed and a set of lateral ridges on at least one neck that allow for the release of air when a solvent is introduced into the transfer device to flush any remaining sample into the container. The lid may be hinged to the body segment.
