Type CO2 is designed for taking out simultaneously chemical substances in extremely small quantities in the carbon dioxide exhaled from animals as well as the urine and feces, making the most of the innate advantages of METABOLICA® which can produce an enclosed living space.
The main object of the experiment is to take up the combined specimens in extremely small quantities by absorbing the whole volume of CO2 in the exhalation into the monoethanolamine solution. In this case, the CO2 gas in the air taken from the atmosphere must be canceled in advance by adsorbing through the soda lime tube.
With type CO2, kinds of specimens are to be collected simultaneously, so the operation panel is set up in front of the apparatus for easy handling.
In the exhalation-absorbing cassette, a soda lime tube for adsorbing the CO2 gas in the taken air, absorbing tubes for the CO2 gas in the exhalation, empty traps, and air flow meters are accommodated in a component unit. Therefore, the apparatus is very compact and needs no extra space.
The urine and feces can be stored without being changed in quality or decomposed, for instance, by immersing each bottle into the S.S. dewar.
