Abstract
A valve block assembly with internal delivery channels and a common outlet channel is provided. Access of reactants to the delivery channels is controlled by diaphragm valves, preferably equipped with relief grooves to accommodate deformation of the diaphragm. Reservoirs feeding the delivery channels have an inert atmosphere controlled by pressurizing and venting channels in the valve block. Exposure of plastic tubing to oxygen is kept to a minimum. The assembly is particularly adapted for use in a DNA or protein sequencer to supply reactants without cross-contamination or oxidative decomposition.
