SieNA
is a modular
robotic magnetic purification system for Sample Prep needs in molecular
diagnostics and clinical microbiology. The stand-alone system
combines a magnetic processor, sample carcode reader and a servo
controled robtic arm to automate any pipetting protocol. As the
automation need may change during the long lifetime of SieNA, the
modular design allows for the addition of pluggable modules later to
increase the sample throughput or changes in the extraction
protocols. Additonal magnetic processors and pipetting pumps may be
integrated in Siena.
Magnetic
Mixing
Based on the
proprietary MixSep™ process, this unique purification technique
utilizes a rotating magnetic field to re-suspend and mix the
magnetic particles without “fluid shear” ensuring unparalleled
purification efficiency even at very low levels of the target
substance.
Liquid Handling
Servo driven
pipetting arm integrates a modular pipetting system for fast
positioning of pipettes for aspiration and transfer of samples,
reagents and purified samples in the volume range of 10ul up to
2000ul. All pipette systems are independently driven by micro
annular gear pumps and equipped with liquid level sensors. The
standard two pipette systems can be expanded to include four
independent pipettes and either washable or plastic disposable
tips can be employed. No maintenance or replacement parts required
for the pipette
pumps.
