Leica Biosystems has become aware of a reagent leakage issue associated with a tubing connection to a manifold in a small number of the HistoCore PELORIS 3 instruments. Our investigation has identified that the root cause of the leakage is due to isolated instances of incorrectly assembled fittings on a batch of manifolds. Leakage may expose instrument operators and other laboratory personnel to toxic reagents and pose a slip hazard. In case of significant leakage, tissue processing may be impacted.
