SP19 Groundwater Sampler for 1.75 drill rods

Geoprobe® Screen Point (SP) Groundwater Samplers have become standard equipment for direct push operators completing environmental investigations since its introduction in the 1990s. The magic of the SP system is its ability to deliver a protected sampling screen to depth and then to  expose that screen to the formation.

SP19 Groundwater Sampler

The SP19 Groundwater Sampler is designed for use with the Geoprobe® 1.75 rod system, common among Direct Image® operators who perform MIP, HPT, and OIP logging. The heavier rods have a much longer life than the 1.5-inch rods, plus they have dependable O-ring seal at the rod joints. The 1.75 rod makes a good choice for the continuous driving of groundwater profiling, logging, or sampling.

The SP19 sheath, as with all SP Groundwater Samplers, is built with a larger diameter, 1.875 inches (48mm), than the rod system. This larger diameter serves as a friction reducer during driving and also seals the hole as the sheath is retracted to expose the SP screen. Updated SP22 screens are compatible with the SP19, with lengths available in 12 inch, 48 inch, and 60 inch (13 inch, 42 inch, and 60 inch exposed lengths respectively).

SP16 drive points and accessory extension rods for holding down the screen are compatible with the SP19.


Latching SP19


The NEW SP19 with a modified drive head has 59% more area included in the sheath head making it stronger and more durable. Utilizing the latching sampler, connect a pump or other sample line directly to the top of the SP19, isolating the SP19 from water in the rod string above to assure sample integrity. This allows collection of high-quality groundwater samples from an isolated screen in the subsurface.

The SP19 Drive Head (MN 237852) is a “Latching” drive head and is compatible with the latching samplers. When operating the mechanical syringe or bladder pump within this sampler, Geoprobe® recommends using the mechanical actuator (MN 214106) for sample collection.
