An improved cartridge and method of dispensing test elements therefrom, which seals off the elements from exposure to the atmosphere. The cartridge includes, at its end apertured to eject test elements, a cover plate, said plate optionally being biased into contact with the end-most test element to cover the fluid opening provided in all such test elements. To dispense that end-most element, a pusher blade engages and ejects the element as in conventional cartridges. Optionally, the opposite end of the cartridge is sealed with a duck-bill seal.
