Raven CORETAKER is the most durable sludge sampler available. The 1.25" clear polycarbonate tube with ultra violet stabilizers has superior clarity for inspecting settled sludge blankets for color and texture.
The Slip-Lock Coupler has four internal O-rings that seal the clear tubes for a 100% leak proof coupling. Raven's Slip-Lock Coupler is unbreakable in the normal course of usage because it has no 90 degree angles like threaded couplers have.
Raven's CNC machined automatic check valve with internal O-ring has a larger annulus for greater flow through. The ball stop also functions as the fastener for the valve to the clear polycarbonate tube.
CORETAKER® has factory applied yellow depth markers from 1 to 7. Markers 8 through 15 are provided and can be installed by the user if desired.
Additional handling charges may apply due to the 8' shipping length.
