“Sunflower” 3D Mini–Shaker provides adjustable three-dimensional smooth rotation of the platform and is designed for mixing blood samples, for minigel staining and destaining, sample washing, blot hybridization reactions. Mini–Shaker is a compact device with low energy consumption. The use of direct drive and brushless motor allows continuous mixing up to 7 days and ensures reliable, trouble-free operation for more than 2 years. Non–slip, temperature resistant, silicone mat located on the shaker’s platform provides stable position for vessels during shaking. The platform is suitable for placing a versatile dimpled PDM mat for different size tubes. Mini–Shaker can be used in cold rooms or incubators, operating at ambient temperature range +4°C to +40°C. Optional dimpled mat PDM prevents different size tubes from rolling around the platform.
