Reaction container arrangement for use in a thermal cycler
First Claim
1. An arrangement of reaction containers for bringing about temperature cycles in a liquid mixture contained within the reaction containers, which comprises:
- (a) a plurality of reaction containers each having substantially the same shape and dimensions, each reaction container having(i) a first conical wall region, and(ii) a second cylindrical wall region adjacent the first conical wall region, and open at one end to form the opening of the reaction container, the thickness of the first wall region being less than the thickness of the second wall region; and
(b) a plurality of closures, each closure being configured and dimensioned to fit within the opening of a reaction container and close the reaction container in a gas-tight manner, each closure being configured and dimensioned to be piercable by a pipetting needle.

Abstract
A throwaway arrangement of reaction containers each having the same shape and dimensions for bringing about temperature cycles in a liquid mixture contained within the reaction containers. Each reaction container having a first conical wall region, and a second cylindrical wall region which at one end forms the opening of the reaction container. The thickness of the first wall region is less than the thickness of the second wall region. The opening of the reaction container is adapted to receive a cover for closing the container in gas-tight manner when placed on the opening of the reaction container. To facilitate handling and access to the liquids in the reaction containers, the arrangement reaction containers is annular, and the closure of each reaction container can be pierced by a pipetting needle.

10. An arrangement of reaction containers for bringing about temperature cycles in a liquid mixture contained within the reaction containers, which comprises:
-
(a) a plurality of reaction chambers each having substantially the same shape and dimensions, being made in one piece from a plastic with each reaction container being joined to at least one other reaction container by a flexible web, each reaction container having (i) a first conical wall region, and (ii) a second cylindrical wall region adjacent the first conical wall region and open at one end to form the opening of the reaction container, the thickness of the first wall region being less than the thickness of the second wall region; and (b) a plurality of closures made in one piece from the same plastic as the reaction containers, each closure being joined to at least one other closure by at least one flexible web, each closure being piercable by a pipetting needle, and configured and dimensioned to fit within the opening of a reaction container and close the reaction container in gas-tight manner. - View Dependent Claims (13)
