The PP-2 dual pump system provides two reliable, variable-speed diaphragm pumps that operate on 12 VDC (adapter included). The PP-2 is avaliable in two standard flow configurations, 0-2 LPM and 0-5 LPM. It is ideal for generating flows for respirometry and gas sampling applications.

The SS-4 subsampler unites a pump, needle valve and linearized mass flow meter of the highest quality into a tough, compact instrument. Its individual gas ports can be used alone or in any combination, making it a versatile solution for sampling or subsampling in gas analysis applications.
