Aim Lab's PathFinder 350A Archiver is a compact bench top workstation for automating the capping (foil sealing), sorting and archiving of sample tubes directly from analyzer racks into low cost storage racks. When sampling is complete, analyzer racks are loaded onto the PathFinder 350A for processing. Those sample tubes where all requested tests have been completed are foil sealed and sorted into uniquely identified storage racks. Tubes are capped with a laminated foil which seals the tube preventing evaporation and leakage during transport or freezer storage.
