An outer, first container portion (50) has a peripheral wall (52) which has an opening at a first end (56) and at a second end (60). A porous filter (58) covers the second end. An inner, second container portion (70) has a peripheral wall (72) with a region which is formed from a first material which is impermeable to the powdered reagents but is permeable to water and to solutions containing dissolved reagents. The first and second container portions are configured such that the second container portion peripheral wall abuts and is connected to the first end of the outer first container portion. The first and second container portions define a first powdered reagent receiving chamber in the first container portion for receiving a first reagent and a second powdered reagent receiving chamber in the second container portion for receiving a second reagent. The porous filter is impermeable to the first reagent but permeable to water and to solutions containing dissolved reagents.
