How to use the glass airflow dryer and precautions

The glass airflow dryer has the advantages of
fast speed, energy saving, no water, easy to use and simple maintenance.
When using, the glass instrument is placed upside down on the air duct of the dryer, and the filtered clean hot air is blown to the inner wall of the glass instrument to dry quickly
.
The dryer is equipped with a hot and cold air selector switch
.
The dried glass tube can be quickly cooled with cold air, which is easy to operate without being hot
.
The limelight in contact with the glass instrument is made of PTFE, which is clean and resistant to high temperature; The air duct is connected by a movable head, equipped with thick (Φ17mm), medium (Φ12mm), fine (Φ8mm), and the thickness is adjustable
.
Thick tubes are used to dry glass instruments 24 and above, and thin tubes are used to dry glass instruments 14 and 19 and smaller glass instruments
.
The dryer can be used for glass instruments
commonly used in laboratories.
It has the advantages of
fast, energy-saving, no water stains after drying, easy operation, simple maintenance and long service life.
How to use the glass airflow dryer and precautions: 1.
According to the size of the glassware to be dried, connect the air duct of the corresponding specification to the air outlet
of the upper cover.
2.
Turn the temperature setting knob to the desired temperature
.
Connect the power supply and turn on the power switch
.
At this time, the cold air indicator light is green; The motor works, blowing cold air
.
Turn on the hot air switch again, the hot air indicator lights up, and start blowing hot air
.
When the airflow temperature rises close to the set temperature, the hot air indicator turns off and the heating stops (the blower motor continues to work).

When the airflow temperature drops below the set temperature, the hot air indicator lights up and the heating continues
.
3.
After the glassware is dried, turn off the hot air switch first, remove it after the glassware is cool, and then turn off the power switch and cut off the power supply
after making sure that the airflow is cold air.
Note: It is strictly forbidden to turn off the power switch directly after drying the glass air flow dryer, so as to avoid residual heat in the equipment and burn out the motor and other components
