Disclosed is a test cassette comprising a continuous length of test carrier tape (22) in a supply chamber (12), the supply chamber (12) having an opening (52) sized so as to allow the test carrier tape (22) to pass through into a test zone (32) into an uptake chamber (14) where the test carrier tape (22) coils itself onto an uptake mandrel (26), the supply chamber (12) being sealed from the environment whereby the opening (52) of the supply chamber (12) allowing the exit of the test carrier tape (22) has a spacer (42) disposed either side of it, filling the remaining width of the opening (52) of the housing (16), a cover plate (34) being biased by a spring (38) to cover the spacer (42) and tape (22), thus covering the opening (52) and sealing the cassette (10). |
