The Dagan 6400Advanced
is a system, which consists of six fully programmable
High Voltage constant current generators for use with
single or multi barrel microelectrodes. Without the
need of any batteries, precise iontophoretic drug
ejection is accomplished by passing controlled
constant currents through the drug carrying
electrodes.

Current
Monitoring
The
6400Advanced measures the ACTUAL current
passing through the electrode barrel (rather than the
expected current), and displays the current in nA's on
the digital read out monitor. The output current can
also be monitor via a back panel BNC. Each channel
also has a monitor LED that alerts the operator of
electrode "BLOCKING" (microelectrode failure
to pass current).
|
Time
Programming
The
6400Advanced includes the versatile AUTO SEQUENCE
PULSER which switches any or all channels into the eject
mode sequentially for the duration of its independently
preset drug ejection time with a common interval time
between channels. Each channel can also be independently
operated via the front panel controls or an external
digital control. Combinations of these are also
possible.
