30-cm Column heater (CH-30A)
The optional 30-cm column heater heats the column compartment to any
temperature, from 20ºC to 90 ºC, that is at least 5 ºC above ambient. The
30-cm column heater mounts on the side of the system stack.
An active preheater heats the incoming solvent before it enters the column.
The active preheater can be located at the top or bottom of the column
compartment, to accommodate UPLC or HPLC columns. You can disable the
active preheater when solvent pre-heating is unnecessary.
Description
Passively heats the incoming solvent before the solvent
enters the column.
Captures any leakage from the column or column
connections and routes it into the drip management
system.
