DigiPREP Digestion Blocks
Version 16.0
SETTING UP
Place the DigiPREP block in a fume hood. The
controller must not be placed in the fume hood.
With the controller’s power switch in the “off”
position, do the following:
` Connect the block’s umbilical cable to the con-
troller.
Disconnecting or reconnecting the
umbilical cable while the controller
is turned on, especially while it
is on the RUN screen, will likely
result in permanent damage to the
instrument.
` Connect the power cord to the back of the
controller.
` Connect the DigiSET (or DigiSET dongle) to
the back of the controller.
` Connect DigiPROBE (or DigiPROBE dongle)
to the back of the block.
If you are not using the DigiPROBE
or DigiSET, the dongles must be
connected; otherwise, an error
message may be displayed.
` Insert the glass well liner into the DigiPROBE
well (Small hole near right of block).
` If you are using DigiPROBE, insert the probe
into the well liner.
The system is now ready to be plugged in
and turned on. Please see your controller
manual for operation instructions.
OPERATION WITH PROBES
DigiPROBE
DigiPROBE (optional) may be
used with DigiPREP systems
to monitor and control the
sample temperature (when
placed in the sample) or the
block temperature when placed
in the storage well located
on the block).
When using the DigiPROBE with
the DigiPREP HP, a flat-bottomed,
conical flask is recommended for
best results.
Install the probe in the port marked “DigiPROBE”
on the back of the DigiPREP block. If using to
monitor and control the heating of the block via
the sample temperature, insert the probe end into
a control sample with the probe holder supporting
the DigiPROBE. (The 010-515-036 is used with 15
ml DigiTUBEs, 010-500-035 probe holder is used
with 50 ml DigiTUBEs, 010-501-010 is used with
100 ml DigiTUBEs and a 6"(15 cm) probe. The 010-
500-037 probe holder is used with glass digestion
tubes and a 10" (25 cm) probe).
DigiTUBEs are used with DigiPREP
Jr, MS, and LS, up to 115 °C.
When DigiPROBE is not being used it
may be placed in the storage well, located
at the rear right corner of the graphite
block. Ensure that there is a glass liner (catalogue
number 010-500-041) in the well.
The control sample should be a
typical digestion sample. The tip
of the DigiPROBE should be
approximately 1 mm from the bottom
of the digestion vessel.
Serious temperature overrun may
occur during digestion if the
DigiPROBE is not in an appropriate
sample or the storage well. Always
place the DigiPROBE in the storage
well when not in use.
