2010 R&D 100 Winner
eVol from SGE Analytical Science, Ringwood, Australia, pairs a digitally controlled electronic drive and an analytical syringe, overcoming problems associated with air displacement pipettes and dispensing organic solvents. It also removes the human limitations of manual liquid handling. The device incorporates SGE’s patented XCHANGE technology, a magnetic coupling mechanism developed to enable the automated and quick change of syringes, tools, and devices.
This digital positive displacement dispensing system accurately aspirates and dispenses aqueous and non-aqueous, viscous, volatile, and hazardous liquids. Separate aspirate and dispense speeds can be set to allow for variations in sample properties, such as viscosity and vapor pressure. A programmable digital drive removes variability in results from operator to operator. Accuracy is +/-0.2% for a calibrated syringe at full scale.
The eVol complies with global laboratory standards. Calibrations can be done internally. Calibration factors for up to ten syringes can be stored and loaded when the syringe is loaded.
