Solinst 408M Micro Double Valve Pump Assembly Length:3/8" Pump (PTFE) converting readings to Specific ConductanceThe Solinst 408M Micro Double Valve Pump miniaturizes the same double check valve pumping principle as the 408 into a flexible, coaxial PTFE tubing assembly only 3 8" in overall diameter. A small filter pump body at the intake fitted with a sintered 316 stainless steel 50 micron screen feeds formation water into both an outer annular drive line and an inner 3 16" sample line. Compressed gas cycled down the annulus by a surface control unit closes a
