The SSL1 also comes complete with a cradle system, rather than a nonslip mat, to comfortably hold flasks. The cradle-type platform has four rubber cushioned horizontal securing bars with quick release handles. They can be easily adjusted both vertically and horizontally to hold most sizes and types of vessels, including flasks, bottles, and beakers. For example, they will accommodate the following Erlenmeyer flasks or bottles: 12 x 250ml or 9 x 500ml or 6 x 1000ml or 2 x 2000ml.
The main advantage of this cradle system is that it can accommodate different sizes of vessels, a common requirement where shakers are used by different people in the laboratory.

Speed is variable from 30 to 300 rpm. Once set on the digital display, the shaking speed is effectively maintained even over long periods of time. Shaking times can be set to run for 1 to 999 minutes on the built-in digital timer, or the unit can be set for continuous operation.
