Title: (EN) Metering device with radial arrangement of valves
Abstract: front page image
(EN)

A multi-function metering device having a plurality of control valves arranged on an annular support. Each control valve can be controlled independently of the others. The annular arrangement of the valves allows the lines to be kept short so that the metering device is particularly suitable for micro-scale work such as in a sequenator or a synthesis machine for the production of nucleotides or peptides.
