ABSTRACT:
A portable photo chamber for photographically recording the extent of a chemical reaction such as in an immunological test, wherein a substrate emitting radiation such as gamma radiation is supported in facing contact with a film and with intensifying means, so that exposure time is reduced as a result of emission of further radiation such as a visible light from the intensifying means and its recording on the film. The photo chamber includes retaining means for supporting the substrate, which itself is preferably enclosed in a container such as a pipette, and translating means for moving the substrate into closely facing relationship to the film and also to a spaced-apart position within the chamber. In a preferred embodiment, the photo chamber utilizes an instant photographic system with film processing means attached to the chamber, so that the photo chamber is both portable and self-contained for use in remote locations.
