Highest sample integrity!
Manufactured without the use of slip agents, plasticizers, and biocides – substances that have been shown to leach from plastic consumables into the sample and negatively affect bio–assay results or measurements, e.g. nucleic acid quantification by photometric measurements at 260 nm -see Application Note 235 for details
