A: Place the Mini-UniPrep G2 into an autosampler
that takes standard 12 mm × 32 mm profile
vials for automated sample injection into your
instrument. Before your run, ensure that the
autosampler needle height is set to a minimum
height of 5 mm, to avoid contact with the bottom
of the inner glass insert.
B: Pierce the septum and draw the filtered sample
into a syringe for manual injection into your
instrument.
For optimum performance, the assembled and filled
Mini-UniPrep G2 device should be kept in an upright
position and not be subjected to excessive agitation to
prevent the sample being spilled out of the protective
