1.0 I TRODUCTIO
TheThermo Scientific Savant®DNA SpeedVac®odel DNA120, is a dedicated
centrifugal vacuum concentration system for drying low volume ethanol or
isopropanol-water precipitates of DNA and RNA. The Thermo Scientific Savant
DNA120 OP allows for additional drying down of synthetic oligos in Ammonium
Hydroxide (NH4OH). This design incorporates a glass cover, ammonia post-trap
and Ammonia Neutralizing Solution for fully automated, unattended, odor-free
drying. The post-trap is connected on the back, left side of the unit. It is easily
maintained and replaced. The Thermo Scientific Savant DNA SpeedVac
combines centrifugal force with vacuum for bump-free sample drying. Vacuum is
supplied by an integral, oil-free vacuum pump with an automatic bleeder valve.
The Thermo Scientific Savant DNA120 SpeedVac has a chamber heater that
counteracts evaporative sample cooling and accelerates solvent evaporation
rates to shorten drying times. The operator can select LOW (ambient),
EDIU (43 °C), or HIGH (65°C) drying rates with the 3-position switch on the
front panel.
Several different microcentrifuge tube rotors are available for drying ethanol
precipitates of DNA/RNA, isopropanol-water mixtures, amplified reaction
products in buffer, aliquots of radiochemicals, or other low-volume samples (see
section 5). A unique swing-out rotor (RD2 P) for microplates is available as
well.
The Thermo Scientific Savant DNA SpeedVac is equipped with polypropylene
vacuum fittings to avoid leaks and resist corrosion. A chemical trap kit
(DTK120R) and disposable cartridge (DC120R) should be used for trapping
volatile radioactivity when the system is dedicated for drying down radiolabeled
materials.
NOTE:To assure safe operation and best results, read this manual in its
entirety before operating this instrument.

2.0 I STALLATIO (cont’d)
SET-UP
• Install the system on a stable surface that is clean, dry, level, and
within 4 feet (1.2 meters) of a compatible electrical outlet.
• Connect power cord to receptacle on the left side of the instrument
and plug into appropriate outlet. The cover latch mechanism releases
automatically.
WAR I G: Before connecting the D A120 to an outlet, make certain that
voltage,frequency, and amperage match the D A120
requirements indicated on the label on the left-hand side of the
instrument (120VAC / 60 Hz, 10 A or 230 VAC / 50 Hz, 5 A).
If there are any questions, please consult an electrician.
• Place rotor on the drive shaft in the sample chamber. Hand-tighten
the hold-down knob until firmly seated.
CAUTIO : Use only Thermo Scientific designed rotors in the
Savant D A SpeedVac®.
•For 230 VAC / 50 Hz, 5 A units only: A safety latch prevents
the Savant DNA SpeedVac lid from operating until power is applied to
the system. Do not attempt to open the lid unless the unit is
plugged in.
3.0 OPERATIO
The switches on the front panel control operation of the Thermo Scientific Savant
DNA SpeedVac. The LED readout displays “run” parameters in minutes. You may
choose between three drying rates (LOW/ EDIU /HIGH).

Actual elapsed time can be viewed during a run or at the end of a run. When
switch A is set to “OFF”, both timers are at 0.00 (0 hours and 0 minutes). You can
change the settings only when switch A is “OFF”; settings cannot be changed
during a run.
Set switch B to “RUN” to view or change the run timer. Set switch B to “HEATER”
to view or change the heater timer.
When you do not set a run time the timer counts upward (time elapsed). When a
time limit is set, the timer counts down; the display indicated the time remaining.
Using switch C increases or decreases the time setting in 5 minute increments to
to 9.55 (9 hours, 55 minutes) holding down switch C allows you to rapidly scroll
thru the settings until you release the switch.
• When setting the heater timer, above 9.55 (or below 0.05) there
exists a setting of “CCC” (for continuous HEATER operation),
and “OFF” (for HEATER off).

3.1 MODE SELECTIO
The dual timer front panel permits operation of the Savant DNA120 in one of the
two modes. Select switch A to either:
•MA UAL-to initiate a concentrator run that you can start and stop
manually. The run starts when switch A is set to “ ANUAL” when
switch A is set to “OFF”. The unit will end the concentrator run.
or
•AUTO-to start a concentrator run for a predefined time interval. The
run starts when switch A is set to“AUTO”. The run stops
automatically at the end of the predefined time selected. The front
panel maintains two independent timers (switch B).
•RU -timer measures the duration of the current run. You can view
or change this timer, (using switch C) when switch B is set to “RUN”.
Each of the above consists of a user-specified target setting and a timer of actual
elapsed time.
A three-digit display shows hours and minutes. A decimal point separates hours
from minutes. For example, 9.55 indicates 9 hours and 55 minutes. The display
can be set to show either the setting or the elapsed time.
The decimal point flashes when a run is in progress (auto run or manual run). The
decimal point is always lit when a run is not in progress.
3.2 SETTI G A TARGET TIME

Switch A should be “OFF”.
Set switch B “HEATER” to bring the HEATER time to the display. Adjust switch C
until the display shows the desired setting for HEATER. You can select:
• “OFF”-to disable the HEATER.
or
• “CCC”-to operate the HEATER for the duration of the run.
or
• A specified length of time. The HEATER switches off at the end
of this time interval. If a longer time than specified run time is
specified, then the HEATER shuts off at the end of the run.
Start the run by setting switch A to “ ANUAL”.
During the run, you can toggle the unit to display the following information.
• Elapsed run time. Set switch B to “RUN”. Since there is no
present run time, the display counts upward, showing the hours
and minutes that have elapsed in the current run.
or
• Remaining heating time. Set switch B to “HEATER”. If a
specific time setting for the HEATER is selected, then the
display counts down and shows it.
3.3 EXAMPLE OF A MA UAL RU
5

Switch A should be “OFF”.
Before starting the Auto Run, specify, a run time as follows:
Set switch B to “RUN”. Adjust switch C until the display shows the desired duration
of the run in hours and minutes.
Start the run by setting switch A to “AUTO”.
During the run, you can toggle the unit to display the following information:
• Remaining run time. Set switch B to “RUN”. The display now
counts downward, showing the hours and minutes of time left
in the current run.
or
• Remaining heater time. Set switch B to “HEATER”. If a specific
time setting is selected for the HEATER, then the display counts
down and indicates the amount of time remaining before the
HEATER shuts off.
To terminate a run, set switch A to “OFF”.
3.4 EXAMPLE OF A AUTO RU
Thermal energy can be applied to the concentrator chamber to counteract the
cooling effect of evaporation, it maintains samples in the liquid state, and
accelerates the concentration run. The DRYING RATE switch selects the desired
drying rate:
“LOW” maintains the concentrator chamber at ambient temperature.
“MEDIUM” maintains the concentrator chamber at 43° C.
“HIGH” maintains the concentrator chamber at 65° C.
Select the highest drying rate if you desire accelerated drying. To ensure against
overdrying of samples, and possible denaturing, it is recommended that the
HEATER timer be set for only a portion of the total run time (e.g., 50%-75% of total
run time).

5.0 ACCESSORIES

Some drying applications produce exhaust vapors that are hazardous. Even
small volume samples, dried rapidly in quantity in the DNA SpeedVac®, in
aggregate can emit volatile solvents to the atmosphere. Add a post-trap or a
chemical trap.
For samples labeled with radioactivity, Thermo Scientific strongly recommends an
adsorbent filter be attached to the DNA SpeedVac exhaust port. This prevents
release into the laboratory environment. The DTK120R Chemical Trap Kit traps
volatile radioactivity and organic solvent vapors. Periodically, the exhaust from the
DTK120R Chemical Trap should be monitored for radioactivity to make sure the
filter cartridge is not depleted. A typical configuration is shown in Figure 1, shown
on page 6.
For questions regarding a specific application, contact Thermo Scientific.
APPE DIX 1
PROPER HA DLI G OF HAZARDOUS EXHAUST VAPORS
(1) Prewarm the chamber, set switch B “Heater” to med setting 10 to 15
minutes prior to placing samples into the rotor.
(2) When the total volume of sample exceeds 6 to 8 ml per run, a small
amount of aerosol is created at exhaust port. Use the post-trap
assembly to collect the condensate (ANT100).
(3) The DNA SpeedVac is compact enough to place in a laboratory fume
hood, if necessary.
(4) Before using the DNA SpeedVac for applications other than those
recommended, contact Thermo Electron for additional information.
