Maintenance Chips (MNT)
Maintenance (MNT) chips are used when priming the system and performing
instrument maintenance using wizards (described later in this chapter) or
when performing a long-term instrument shutdown. The maintenance chip is
used for these operations because it is not damaged by the maintenance
reagents. MNT chips do not require temperature equilibration (stored at room
temperature) and do not require initialization.
When using a maintenance chip it is important to keep it clean. Before
inserting a maintenance chip into the ProteOn™ XPR36 instrument, it should
be removed from its cartridge and inspected to ensure it is clean. Never insert
a dirty maintenance chip into the instrument.
When an MNT chip is inserted into the instrument, the buffer pump starts
running at 25 μl/min constant flow and consumes 216 ml of buffer in a 24-hr
period. During extended time periods with an MNT chip in place, Bio-Rad
recommends switching the buffer to a full bottle of distilled or deionized water
to avoid wasting buffer and to eliminate the risk of running the system dry.
Following use, the chip should be immediately rinsed with deionized water,
70% isopropyl alcohol and wiped dry with a Kimwipe. When the chip can no
longer be cleaned, it should be discarded.
