Lastly, all formats are available in either standard packaging or radiation sterilized. Strip-Ease PCR tubes are offered in strips of eight or twelve. For smaller volume sample processing, individual thin wall 0.2 mL tubes are also available. All Strip-Ease products are manufactured from virgin polypropylene in our own clean room injection molding facility. The use of the highest quality starting materials insures that a hydrophobic surface is produced on the tubes, preventing liquids from adhering and ensures complete sample recovery.
Some manufacturers use inexpensive recycled plastic, thereby compromising tube performance.
PCR Certified Robbins Scientific is the only manufacturer that certifies its plastics for use in the PCR process by performing functional tests on each lot. Samples of each production run are checked for the presence of PCR inhibitors, human DNA, DNase and RNase by incubating tube extracts with appropriate templates and examining the resulting products by electrophoresis.
