Study investigates inherent contamination in deep well microplates

An independent academic study provides a detailed analysis of deep well microplates and the significant levels of contamination found in more than 50% of the commercially available plates tested.
The study gives data on a large range of microplates from numerous manufacturers based in Europe, USA and China. Mass spectral data shows that persistent contamination from a range of compounds found in the raw polymer master batch continues to be evident in many of the microplates tested. The effect of extractables leached out of the deep well plates identified in this report depends on the exact application for which the plate was designed but is highly likely to significantly affect their performance and contaminate samples stored in them.
The authors of the report conclude it is likely that a low grade polypropylene was used in the production of a significant proportion of the deep well microplates that leached extractables when tested.
