1. General
1.2 Product introduction
This product has the optimized structure for the experiment of the high vacuum level and gas
exchange because the Vent (exhaust) pipe and Vacuum (suction air) pipe are separated, and
also the High Heat Conduction Mechanism realizing the vacuum condition that keeps the high
vacuum level and has not the thermal conductivity by air has been applied in this product.
In addition, it remotely controls the experimental equipment by building Smart-LabTM System
through WiReTM App & web Service, and it is implemented so that anytime, anywhere can be
monitored. This product was developed and manufactured considering the best possible ease
for use and safety, and has the following features.
1. Because the Vent (exhaust) pipe and Vacuum (suction air) pipe connected into the inside of
the chamber are separated, respectively and are connected with outside, separately, the
optimized structure for the experiment of gas exchange can be realized.
2. This product can realize high thermal conductivity by adopting the High Heat Conduction
Mechanism which optimizes the thermal conductivity in the vacuum condition without the
thermal conductivity by air.
3. Because the bracket and shelf attached to the inner wall of the chamber are directly
fastened, high thermal conductivity can be reached to the samples on the shelf, and the
fastened shelf can be separated and can support the experiments of the samples with
various sizes.
4. The highest door sealing structure has been realized by adopting high quality Molded gasket.
5. The internal state of this product can be safely checked through the Highly Safety Viewing
Window.
6. Because Jog Dial Knob and Push Button which are rigid and have excellent operability are
mounted, this product has high operating sensitivity and excellent accuracy.
7. Because this product is equipped with a high-quality LCD Display with back-light function, it
is easy to confirm its state.
8. The necessary matters during the experiment can be conveniently used by the support of
SUB MENU.
9. The safety device for overheating prevention, and over current and short circuit prevention
circuitry that preferentially consider the user’s safety are mounted.

* Connection of Vacuum Pump, and Connecting Method of Cold
Trap Bath
-The size of the Vacuum Nozzle and Vent Nozzle located on the right side of the Vacuum
Oven are OD Φ10mm, so these nozzles should be connected to the Cold Trap Bath or the
Vacuum Pump by using the hose with ID Φ8~9mm (Recommending to use a silicone-based
hose).
* Connection of Cold Trap Bath
-The Cold Trap Bath can economically and effectively shut off that the harmful gas and the
vapor of organic solvent which has a fetal influence on the vacuum device are flowed into
the mechanism, so it can extend the life of the vacuum pump and enable the recovery of
the organic solvent.
-If the gas removed from the inside of Oven has many heat when setting the vacuum, the
Vacuum oil in the Vacuum Pump can be often scattered together the heat of the de-
saturated gas. For this reason, because the life of Vacuum Pump can be shortened, user
must protect the Vacuum Pump by cooling the de-saturated gas with the Cold trap.
-When air is injected into the Chamber of the vacuum condition at the time of vent setting,
the samples of the vacuum condition should be protected from other components contained
in the air.
* Connection of Vacuum Pump
-The Vacuum Pump makes the inside of chamber of the Vacuum oven to the vacuum state,
and the vacuum pump model can be selected according to the desired exhaust speed
(L/min).
-The vacuum pump should be installed in the place where is easy to install or remove it and
to perform the work, such as checking and cleaning, and please install this device with
attention to the ambient temperature if fixing it. In addition, please install using the
vibration-proof and rubber, etc. so that the vibration is not transferred to the vacuum pump.

the device at a poor ventilated place or use closed. It may cause a fire or damage
of the device as not to release heat or insufficient ventilation may result.
Please, do not use the samples with sublimation property. Because the sublimable
sample can block the Vacuum line by sublimating before the boiling point and it
can damage the pump, the use of such samples is forbidden.
If user wants to maintain the vacuum state, the Pump should be stopped after
closing the Vacuum Valve, first. First, If the pump is stopped, the oil of pump can
be flown in the inside of oven due to the vacuum in the oven.
The experimental temperature in the vacuum state should be set up lower than
the experimental temperature at the atmospheric pressure.
