Pre-NAT II

The Pre-NAT II allows fully automated high-throughput sample preparation for molecular genetic diagnostics, consisting of nucleic acid extraction and subsequent pipetting of the PCRs. In this way, up to 96 primary samples from various source materials are prepared efficiently, safely and without any manual intermediate steps for subsequent PCR-based tests, e.g. EUROArray and EURORealTime.

After automated barcode identification of the sample tubes, the cell material is lysed and the nucleic acids are extracted by means of magnetic particles. These are subsequently transferred one after another into the automatically dispensed reagents by magnetisable metal rods. In this way, there is no risk of cross-contamination during the transport of liquids. Afterwards, the liquid-handling module of the Pre-NAT II automatically pipettes the prompted PCRs using the extracted nucleic acids and the PCR reagents, which are stored refrigerated in the instrument.

  • Fully automated instrument for nucleic acid extraction for up to 96 primary samples and preparation of up to 288 PCRs per run
  • Various further applications of the PCRs possible, e. g. for EUROArrays and EURORealTime tests
  • Established nucleic acid extraction system based on magnetic particles
  • Pipetting without carryover of sample material, using disposable filter tips, as well as an efficient and resourcesaving dispensing system for extraction reagents
  • User-friendly instrument software with clear graphic visualisation of all process and run times
