A device which can dispense a composition such as a pesticide, herbicide, fungicide, or other toxic composition into a liquid such as a solvent without exposing the composition to the atmosphere. The device comprises a jacket having a perforated top and an open bottom; a container having an open top which is sized to be removably retained within the jacket; a means for breaking a seal over the top of the container only after the container has been sealingly engaged within the jacket; a means for sealingly engaging the container and the jacket after the container has been inserted a predetermined distance into the jacket; and a graspable element coupled to the base of the container for allowing the container to be manipulated when the container is retained within the jacket.
