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. 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.
10. This product is remotely controlled by connecting to PC through RS232 communication port, and
can be transmitted data.

* 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.
