2 System description and options
Your HT-8 and/or HT-12 Evaporation System is
comprised of an evaporation chamber and rotor, with
an external a cryopump-condenser unit.
Vacuum is provided by the Scroll Pump, although
other types of vacuum pumps can be used.
Solid-state case heaters and Coolheat radiant lamps
heat the chamber and samples.
The control of chamber, bucket and sample
temperature, vacuum ramping rate, chamber
pressure, rotor speed and run time are all handled by
an embedded PC.
The end user has the facility to auto program run
parameters for any (recognised) solvent/mixture
entered. These optimised run parameters are
highlighted in
Cyan
on the display screen, when this
Auto Program
facility has been selected.
Recognised Solvent(s) available from drop down
menu.
Sample Holder type available from drop down menu.
Lyophilisation (Freeze Drying) is available as a Rotor
Speed (Very Low (50g)) selection on evaporators
equipped for this configuration.
Please note:
Lyophilisation samples are to be frozen
prior to being placed in evaporator.

is available, providing it was
specified at the time of placing the order.
The
Run Progress
screen now has a fully featured
graphical display, providing annotated plots for
temperature and pressure (now a log scale).
The control software enables the user to specify and
store a library of up to 100 different evaporation
profiles in an uncomplicated manner.
Run profiles can also be linked to provide multi stage
runs. Up to 100 different profile steps can be linked
and iterative loops can also be programmed.
With a maximum single run time of just below
100 hours, the system is extremely flexible to
meet every requirement.
