Solinst 103231 1.66" Bladder Pump Drop Tube Assembly

Solinst 103231 1.66" Bladder Pump Drop Tube Assembly. The Solinst 1.66" Bladder Pump Drop Tube Assembly allows samples to be obtained from greater depths than the standard 500 ft. (150 m) below grade for Solinst Bladder Pumps. The Drop Tube places the screened filter intake of the Pump as deep as necessary to access the sample zone desired. The Drop Tube Assembly is easily installed on existing pumps, even in the field. Pumps are operated in the same manner as those without a Drop Tube, which maintains high sample integrity.
