Method of operation
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
