Automatic sample preparation system

Reduce expensive lab space by condense most functionalities on a small footprint. The accroma does not require lab infrastructure and can operate 24/7 in normal commercial space with electricity. #1 Rack The rack of the accroma system is incorporated into the door for optimal access and has 124 positions. It can hold multiple formats like sample- and dilution tubes, centrifuge counterweights and tubes containing reagents for dispersive solid phase extraction (dSPE). To maximize flexibility, additional solvents and filter types can be placed on the rack as well. • Sample Tubes • Dilution Tubes • Additional Filter Types • Centrifuge Counterweights • Additional Solvents • dSPE tubes #2 Shaker • Milling • Extraction • Homogenization The shaker accelerates accroTubes vertically with a standardized frequency and amplitude. By shaking the tube either milling or extraction can be performed. By adding one or multiple milling aids like a steel ball into a tube turns the shaker into a ball bill but without sample loss. Even the hardest samples can be grinded by the powerful shaking. If solvent is added to the tube prior shaking, the process is called wet milling or homogenization, which combines milling and extraction into one step. • No sample loss • Reproducible • Quick • Shortens extraction times #2 Analytical Balance • Weighing The balance from Mettler Toledo is the central verification element of the accroma system. Tubes are tared and gross weights are determined after the insertion of samples or solvents. Volumes are calculated from the measured mass with solvent densities.
