As the need to determine the genomic profi les of food and commercial crops expands, the requirement for reliable methods of extracting the plant DNA increases. Standard methods such as bead-beating or grinding mills have traditionally been used. When conducted in polypropylene microplates, the extreme forces applied by commercially-available bead-beating machines can cause damage to the plates leading to cracking, leaking and ultimately, cross-contamination.
Good quality injection molded polypropylene microplates for science should be free of extractable compounds and additives. Such additives, designed to strengthen household products, are definitely not suitable for scientific applications and therefore J.G. Finneran and Porvair Sciences have taken a diff erent approach.
