Automated sample preparation enables efficient, standardized purification of nucleic acids. The EZ1 Advanced XL enables purification of nucleic acids using proven magnetic-particle technology for use in routine in vitro diagnostic applications. Reagent production is subjected to stringent quality control assuring reliable and robust performance. An easy-to-use instrument, prefilled and sealed reagent cartridges, and simple protocol selection and worktable setup help to prevent handling errors and allow the system to be operated by anyone — from the novice to the expert. Manual handling of potentially infectious samples is minimized, ensuring safety to the user and reliable processing of samples. Purified genomic DNA is ready to use in sensitive downstream diagnostic assays based on enzymatic amplification, such as polymerase chain reacation (PCR) for genotyping.
