The Model 404 Inertial Pumps are a simple and inexpensive option for groundwater sampling, purging and monitoring well development. Pumps are able to handle very silty water. They are ideal for dedication.

The Inertial Pump consist of a length of riser tubing, LDPE or PTFE, with a one-way footvalve connected to the end. Various diameters are available, and stainless steel or Delrin┬« footvalves are offered. Sizes range from a Mini 1/4″ (6 mm) OD Inertial Pump to a 1″ (25 mm) OD Delrin footvalve. The sizes allow options for 0.4″ – 6″ ID wells. When operated by hand, depths of 100 ft. (30 m) can be reached.

The 1/4″ (6 mm) OD Mini Inertial Pump (MIP) is made for sampling from the narrow channels of a Solinst Model 403 CMT System.

The Model 860 Disposable Filters meet filtration requirements and provide a quick and safe method for preparing groundwater samples for metals analysis and for filtering large volumes of turbid water. They have 650 cm2 of effective filtration area and use a 45 ?m membrane. The polypropylene filter is disposable, saving the need to decontaminate or replace filter discs. The filters have a 3/8″ (9.5 cm) hose barb inlet and outlet, and a 1/8″NPTM vent/drain connection.
