A chemical reaction pack and method of using same

Abstract

Abstract In techniques for detecting nucleic acid material, there is a risk of contamination during unstoppering of reaction containers and transfer of liquids used in such reactions. This is because aerosols are produced during such unstoppering and transfer, which may contain some amplified nucleic acid material. Described herein are improvements in a disposable chemical reaction pack (10) and method for examining fluids using such a pack, in which liquids can be reacted and examined without the need to unstopper the reaction container and transfer the liquid to a further container for examination. The pack (10) comprises a first chamber (20) into which liquid to be examined is first inserted and sealed. This chamber (20) is connected to a second chamber (24) in which the liquid is examined. A rupturable seal (34) is provided between the first and second chambers (20, 24), which allows liquid to flow from the first chamber (20) into the second chamber (24) once linear pressure has been applied to the liquid in the first chamber (20). Advantageously, an expansion chamber (22) is provided intermediate the first and second chambers to control the velocity of liquid transfer from the first chamber (20) to the second chamber (24).
