Quality Importance for Deep Well ­Microplates

Porvair Sciences have announced a new technical report that demonstrates the importance of high quality raw material selection for the manufacture of deep well microplates. Deep-well plates today find widespread use in rapidly ­expanding applications including cell growth monitoring, combinatorial chemistry and sample storage. In all these applications it is critical that the deep well plates do not negatively impact sample integrity. Polypropylene is a material commonly selected for deep well microplate manufacture because of its inertness and heat resistance. The technical evaluation report concludes that not all polypropylene deep well ­microplates offer the same level of protection of sample integrity. Further use of some grades of polypropylene used in commercially available deep well plates can lead to sample contamination due to leaching of moulding aid chemicals present in the raw polymer.
