A test device by immunochromatography comprises a case including a dropping window for a specimen and a detection window, and a test piece in the case. The test piece includes first and second detection portions, and a dropping area common to the first and second detection portions. When the specimen is dropped on the dropping area through the dropping window, the specimen migrates downstream and the same specimen reaches the first and second detection portions. The first detection portion traps a complex of a first labeled body and a first antibody contained in the specimen. The second detection portion traps a complex of a second labeled body and a second antibody contained in the specimen. The first antibody is produced by vaccination or infection with a predetermined virus. The second antibody is produced by infection with the virus. Thus, a test result from each of the first and second detection portions, both visually observed through the detection window, can be determined in parallel and at the same time.

A gas detector is provided and includes a gas detector element, electronics to interface with the gas detector element and an enclosure configured to expose the gas detector element to an exterior and to form an electronics housing area in which the electronics are disposed whereby the electronics are isolated from the exterior.

A fluorescence microscope system for imaging a sample having at least two different fluorophores includes an illumination system configured to emit illumination light for exciting the fluorophores; an optical detection system configured to generate images of the sample based on fluorescence light emitted by the excited fluorophores; and a control unit configured to determine whether to image the sample in a concurrent imaging mode or in a sequential imaging mode, based on at least one characteristic of each of the fluorophores and based on at least one parameter of the optical detection system and/or the illumination system.
