At approximately 500mm² the OS sits very comfortable on the benchtop but is best suited when used on its tailor made trolley. The OS trolley ensures that the equipment is situated at its optimum working height and is mounted on full swivel and lockable casters that enables safe and free movement of the equipment when needed. The OS is capable of processing volumes from 0.5mL to 8mL per process with a dead loss volume of < 0.1mL per process.

The OS is recommended for total volumes of up to 24mL which is ideal for those users who wish to upgrade from small bench-top techniques such as bead beating and sonication. The OS takes advantage of Constant Systems precise and consistent hydraulic control which is fully scalable through the whole product range from 0.5mL single preparation processing to large volume processing at 150L per hour. This precise control ensures that the entire sample is processed at the operators set pressure to ensure accurate and consistent results and in most cases a single process or pass is adequate therefore multiple passes are not required. The OS model can be utilised for processing fluid, re-suspended, viscous, tissue, plant and frozen sample types.
