Labnet’s Revolver lab sample rotator accepts a variety of tube sizes and mixes them horizontally, vertically, or any position in between. Changing the mixing angle is easy simply turn the rotisserie. No tools are required. Interchangeable rotisseries accept tubes from 1.5 ml to 50 ml. Each rotisserie is split into two halves. Each of the halves can be exchanged to mix more than one tube type at the same time. Each rotisserie half can be rotated independently from a center point on the shaft. Placing the halves in line with the shaft produces an end over end tumbling motion, similar to that used to mix blood tubes. Rotating the rotisserie at a right angle to the shaft produces a gentle mixing motion, ideal for delicate samples. Any position in between these two extremes may be selected to achieve the desired mixing action. Rotation speed is fixed at 18rpm (20rpm for 230V models). The Revolver lab rotator can be used in ambient temperatures from 4°C to 55°C, making it ideal for a variety of laboratory settings such as Molecular Biology, Biochemistry, clinical and Histochemistry. Small enough to fit on a crowded bench, the rotator is easily moved where it is needed – the bench, cold room, incubator or biological hood. With a molded housing and unique rotisserie design, the Revolver is easy to clean and decontaminate. A 36 x 1.5/2.0 ml rotisserie is supplied with the Revolver. Other configurations are available separately.
