A reagent dispenser is provided for dispensing multiple reagents particularly for use in analyzing biological specimens and the like. The dispenser includes a pair of reagent chambers with selected reagents therein, and a dual nib for hermetically sealing the reagent chambers. A portion of the dispenser is deformable to break or otherwise to displace the nib in a manner permitting the two reagents to flow together and mix within one of the reagent chambers. The deformable portion or the dispenser can then be squeezed to express the mixed reagents for delivery to contact a specimen to be analyzed. In a preferred form, the dispenser is cap assembly for removable mounting onto an open-ended tubular housing to cooperatively define a specimen chamber within the housing for receiving the specimen on a swab or the like. |
