Claim 15:
16. A method of assembling apparatus for containing reagents for a chemical reaction, the method comprising:
(i) selecting an elongate receptacle comprising a plastics material, said receptacle being arranged to define an internal volume for containing reagents, wherein said receptacle includes a first end and a second end which are spaced apart along the elongate extent of the receptacle, wherein said receptacle defines a mouth at said second end, wherein said mouth has a diameter which is defined as the longest straight line passing from one side of the cross-section of the receptacle to an opposite side, when the receptacle is configured to define its maximum cross-sectional area;
wherein a region of said receptacle inwards of said second end has a diameter which is defined as the longest straight line passing from one side of the cross-section of the receptacle to an opposite side, when the receptacle is configured to define its maximum cross-sectional area;
wherein the diameter of said mouth is greater than the diameter of said region of said receptacle inwards of said second end;
(ii) selecting a housing for containing the receptacle, wherein said housing includes a first end and a second end, wherein said second end of said housing includes an outwardly facing surface;
(iii) with the receptacle within the housing such that the second end of the receptacle is adjacent the second end of the housing, positioning the second end of the receptacle over the outwardly facing surface;
(iv) securing the second end of the receptacle in position relative to the outwardly facing surface;
wherein said mouth is permanently deformed so that the diameter of said mouth is greater than the diameter of said region of said receptacle inwards of said second end.
