Abstract
Methods and apparatus configured and adapted to provide less carryover in an automated clinical analyzer are disclosed. The methods include immersing a pipette into a neutralizing liquid vessel and aspirating a neutralizing liquid (e.g., a hypochlorite solution) into an interior of a pipette. The aspirated portion of the neutralizing liquid used to cleanse the pipette interior is then dispensed back into the neutralizing liquid vessel, rather than disposing of the used neutralizing liquid to a waste station. Apparatus and systems configured to carry out the methods are provided, as are other aspects.
