" Addition and Subtraction Key: When setting parameters, it is used to increase or

decrease the value.

2.Temperature setting:

Press "

a. Put the digestive tube containing samples in vitro digestion rack, will waste gas in the in

vitro digestion absorption equipment rack (hands holding a waste gas absorption bottle, to absorb

the gas bottle seal on the digestive tube, cover can.)

b. According to the above diagram, connect the tap water and the pumping pump, and pay

attention to the proper water flow (3/4l /min). First pick good extraction tee (the suction filter

pump), adjust flow after connected to the gas absorption tube (besides using standard, our

company also with another high matches: vacuum pumps, filters, and exhaust gas absorption

equipment connection. This method can neutralize the harmful gases such as SO2, which is easier

to operate.

c. Connect the power cord in the fitting, open the main switch of the ship type power supply,

the temperature instrument is bright, and the first infrared quartz tube is energized to start the work;

Press the power switch 1, and the second infrared quartz tube begins to heat; Press the power

switch 2 the third infrared quartz tube begins to heat.

d. According to the instrument instructions and set the temperature in two stages: first of all,

first set to a temperature of 200 degrees, after reaching the temperature continue to heat the 20-30

min, and then reset the temperature continue heating 30 to 60 min after 450 degrees, then the

sample will gradually stop boiling, and then began to change color, when the sample color

becomes completely transparent blue-green liquid continue heating 10-20 min, after digestion to

complete at this time.(such as moisture content is exorbitant, heating of the digestive wall with

black objects, to extend the heating time until the color of the sample becomes transparent

blue-green liquid)

Generally, the time required is 60-90min from the boot to the sample, which is determined

according to the sample (the higher the nitrogen content, the longer the digestion time).

e. After the digestion is completed, it will be moved to the test tube cooling rack together

with the tube digester and exhaust gas absorption device.
