APPARAT ZUM STUFENWEISEN DURCHFUEHREN VON CHEMISCHEN REAKTIONEN.

摘要

An apparatus for the stepwise performance of chemical reactions comprises a cup-shaped reactor vessel (1) spinning around its longitudinal axis and a pipette (11) for applying sample, reagents and solvents onto the inner wall of the vessel. The pipette (11) is slewable around an axis (23) and can be positioned at a location (17) from which it can be lowered into reservoirs (51, 5b) for drawing in or for ejecting liquid; the pipette (11) can furthermore be positioned at a location (19) from which it can be lowered into the vessel (1) for applying sample, reagents or solvents onto its inner wall or it can be positioned at a location (18) from which it can be lowered to remove reaction products and excess products from the bottom of the vessel (1). The apparatus can be used for automatically sequencing proteins or peptides (Fig. 1).
