Abstract
An apparatus for the stepwise performance of chemical reactions characterized by a cup-shaped reactor vessel spinning around its longitudinal axis, and a pipette for applying samples, reagents, and solvents onto the inner wall of the vessel. The pipette is rotatable around an axis, and can be positioned at a location from which it can be lowered into reservoirs for drawing in or for ejecting liquid. The pipette can furthermore be positioned at a location from which it can be lowered into the vessel for applying sample, reagents or solvents onto its inner wall or it can be positioned at a location from which it can be lowered to remove reaction products and excess products from the bottom of the vessel. The apparatus can be used for automatically sequencing proteins and/or peptides.
