The 3-D Orbital Shaker Attachment for the Roto-Shake Genie provides gentle yet thorough mixing of dishes, flasks, beakers and open containers. It moves at a 5 degree angle through a 360 degree rotation (providing a combination of vertical and horizontal motions). This means that every corner or crevice of a container will receive complete mixing, making it the perfect choice for applications such as gel and blot staining/blocking, sample washing, polymer resin preparation, and more. Please note, platform capacity is 1 Kg (2.2 lb).
