Contamination with cadmium from micropipette tips.
Contamination by cadmium from micropipette tips from two different manufacturers was tested. Tips were washed with two different acids and the washing solutions were analysed by atomic absorption (graphite furnace). The washed tips were controlled by analysing pure acids and were found decontaminated. Clear contamination was found in yellow Eppendorf pipettes, which varied according to the consignment. The decontamination of disposable micropipette tips is emphasized when trace metal contamination should be avoided.
