The QuatroProbe offers long term instrument reliability, with sophisticated yet simple electronics, mechanics and software, offering automatic washing and purging cycles. Based on Magnetic Bead technology, the samples are placed into disposable QuatroPacks, supplied with the kit, with each QuatroPack holding up to 4 samples for processing. The chambers in the QuatroPacks are spaced 9mm apart for easy access with a multi-tip pipette. Heat can be applied to enhance lysis and/or elution.
