Flow Rate Control (0,1 – 3 mL/min)
Hydrogen Mode, see endnotes
CatCart® Heater
Pressure controller 1 bar = 14,5 PSI
Stops the pump but keeps hydrogen
Stops the pump and vents hydrogen
If using elevated temperatures, always allow the system to cool to 40°C
before attempting to remove the CatCart®.
Ensure the water reservoir is topped up at all times. The cell must not be
allowed to run dry or the cell will cease immediately and irreversibly to
function.
During use, the perspex cover on the H-Cube® must be closed.
Spent CatCarts® should always be placed into deactivating vials prior to
disposal.
Normal COSHH stipulated procedures for the safe handling of chemicals
should be followed at all times
Fill up water tank
Switch on H-Cube®
Flow Solvent
Through System
Insert CatCart®
Wait until you see solvent eluting
from the reaction line!!!
Set Temperature and Pressure and Mode
on touch Screen, Press START
CONTROLLED MODE
FULL HYDROGEN MODE
Wait until hydrogen is
eluting from the reaction
line and the hydrogen
output is constantly under
25 in the bubble detector
box on the Service Screen
Wait until hydrogen comes
out of the reaction line
Transfer pump inlet line over
to the reaction mixture
When the reaction mixture is
almost dry, add reaction
solvent-Wash for 10 mins.
When you have finished
flushing the system with
solvent press Stop or Stop
and Keep H2 on the touchscreen and Stop on the pump

For reactions at 1 bar-Use Full Hydrogen Mode
For best results in controlled mode start at 50 bar
For solvent compatability-see page 66 of the manual
