Introduction
The document discusses the increasing need for reliable methods of extracting plant DNA due to the expanding requirement for genomic profiling of food and commercial crops. Traditional methods like bead-beating can damage microplates, leading to contamination.

Product Overview
Porvair Sciences has developed deep well microplates designed to withstand the forces of bead-beating machines. These microplates are made from pure, virgin polypropylene, free from extractable compounds, ensuring no contamination during DNA extraction.

Design and Features
The microplates feature reinforced walls and supporting ribs, providing strength and stability. They have a 2 ml square well block with a total volume of 2.12 ml and a working volume of 1.90 ml per well. Matching cap mats are available, including a special polypropylene cap mat for freezing at -80ºC, which prevents cross-contamination by expanding and shrinking at the same rate as the plate.

Performance and Testing
Data from a UK sequencing laboratory shows these plates can endure four minutes of bead-beating at 1750 rpm with no damage. The plates are available in sterile versions and come in packs of five, with cap mats in packs of 50.

Additional Products
A magnetic separation plate compatible with these microplates is available for those requiring magnetic separation.
