Quality manfactured device for creating highly reproduceable, linear gradients for density-gravity centrifugation applications, for gel-electrophoresis and for column-chromatographity. Can be used with magnetic stirrers for mixing of phases. Equipped with a solid base for secure positioning. Available in 7 different models. The smaller devices are manufactured out of a solid acrylic block. Devices for bigger volumes are made of 3 parts (2 vessels, 1 base) All gradientmixers are equipped with a hose a fitting at the side and stop valves.
