It continues to provide a smooth, quiet, reproducible and uniform orbital shaking motion (19mm circular) for a wide range of laboratory applications such as cell per tissue culture, hybridization, staining and destaining gels and much more. This advanced orbital shaker has a programmable memory for up to 4 different programs. Its easy recall function allows for quick entry of your program. Furthermore, the VSOS-4P has a pulse operation for a short processing run. The VSOS-4P's digital capabilities allow you to visually set the rpm speed and time.
