In one of the more stringent tests, Porvair microplates and mats maintained structural integrity while powdering dry samples of human hair in the Mini-BeadBeater-96 using two 3.2 mm chrome steel beads in each well .  In contrast, all other plates cracked during use and some even had holes punched through them under the  severe test grinding conditions.  Independent support for these findings come from a leading UK contract genomics laboratory. Testing barley seeds, a notoriously hard carpel to crack, they reported that Porvair deep well microplates sucessfully survived 4 minutes of bead beating using a single 6 mm steel in a high speed shaking bead mill. Plates are made from virgin polypropylene Mats are made from EVA Tested for low extractables Tight specification levels V-bottom to allow total liquid removal, partial collection and to aid re-suspension No inner edges to allow better collection of magnetic beads Manufactured under a DNase/ RNase free environment Plates are autoclavable Working volume of 2ml Raised well rims to improve heat  sealing Conical base which aids sample concentration, reconstitution, and centrifugationYou May Also Be Interested In...Mat Roller1 1/2' rubber roller, for hand pressing mats onto microplates.
