Plate is thin-walled and designed for rapid thermal transfer. Precision molded to ensure well-to-well and plate-to-plate uniformity. The flexible design accommodates differences in expansion coefficients between the metal thermal cycler block and polypropylene tubes. An alphanumeric grid helps in sample identification. To facilitate orientation, the two left corners of the plate are cut away. The amplate is easy to seal since no cylindrical wall extend above the plate. More economical than using single tubes. Autoclavable. Packed in cases of 100 with tamper-proof, re-sealable bags of 10 plates each.
