Compressed air collector NCAC-200 is used to determine the microorganism according to the specifications of the new GMP method and the microbiological detection for phytoplankton sampler is up to 50L/min, 100L/min. In the sampling process, the input gas is not wasted, and 100% of input gas is applied to the process sampling. The core components are imported from the original two compressed air collector and compatible gases used are helium(hr), argon(Ar) and nitrogen(N) gas also Adjust the cavity pressure in the body, but on meter readings, observe whether the appropriate adjustment.
