Reagent cartridges are prefilled with all reagents required for the purification procedure, including accessory enzymes, and are labeled with 2D bar codes. Partially used cartridges can be resealed for later use giving you complete cost control.
The QIAsymphony SP processes a sample containing magnetic particles as follows. A magnetic rod protected by a rod cover enters a well containing the sample and attracts the magnetic particles. The magnetic rod with cover is positioned above another well and releases the magnetic particles. The QIAsymphony SP uses a magnetic head containing an array of 24 magnetic rods, and can therefore process 24 samples simultaneously. Steps 1 and 2 are repeated several times during sample processing.
