Abstract: A reagent cup device 1 includes a plurality of individually sealed reagent cup compartments 7, each holding a reagent cup 8 having an open end and an inner surface, at least part of which is coated with a chemical reagent. Each reagent cup compartment 7 is closed and has a first end covered by a first breakable seal 5 and a second end covered by a second breakable seal 10. Since the reagent cup compartments 7 are individually sealed by the breakable seals 5, 10, it is possible to gain access to the interior of a reagent cup compartment 7, and thereby to the reagent cup 8 held therein, without breaking the sealing of the remaining reagent cup compartments 7. Thereby degradation of the chemical reagent in the reagent cups 8 is reduced, and the expected lifetime of the reagent cups 8 is accordingly increased. The breakable seals 5, 10 may be provided with weakened zones in order to easier break the seals 5, 10 when access is desired.
