Method for carrying out a biochemical protocol in continuous flow in a microreactor
First Claim
1. A method for carrying out a chemical or biochemical protocol comprising:
- depositing liquid sample volumes into a plurality of sample receiving regions on at least one mobile sample transport member; and
moving the sample transport member along a pathway such that said sample receiving regions move through at least one temperature regulated zone upon which a thermal transfer member acts, wherein said thermal transport member cycles between at least two temperatures while said sample receiving regions are moving through said at least one temperature regulated zone; and
whwrein the protocol is carried out in an atmosphere sufficiently humid to reduce or prevent evaporation of the liquid sample volumes.

Abstract
Devices and methods for carrying out a chemical or biochemical protocol are disclosed. In one embodiment, the chemical or biochemical protocol is performed by cycling at least one thermal transfer member between at least two temperatures while liquid samples on which the chemical or biochemical protocol is to be performed are continuously moving through at least one temperature regulated zone upon which the at least one thermal transfer member acts. In some embodiments, the device comprises a sample transport member that comprises liquid samples in sample receiving regions. The sample transport member moves the samples continuously through a temperature regulated zone which cycles between at least two temperatures while the liquid samples are moving through a temperature regulated zone on which at least one thermal transfer member acts. In some embodiments, the sample receiving regions comprise wells, hydrophillic films or hydrophillic filaments.
