The bottom sediment sampling equipment also named stainless steel Sediment Sampler or Sludge Sampling Grab, is a kind of manually operated grab bucket for river bottom sludge collection.

It is suitable for collecting underwater sediments and sediment in rivers, lakes, reservoirs and other places. The Bottom Sediment Grab Sampler is a kind of laboratory equipment, which is used for collecting mud(sediment/sludge/deposit) samples from the bottom of rivers, lakes, ponds, shallow sea etc.

The simple design means it is simple to use. Heavy duty hinges and the hinge pins can absorb thousands of bottom impacts. Self-closing scoops have centre pivot closing action.

When the scoops strike the bottom, their tapered cutting edges penetrate well with very little sample disturbance. An attached underlip wipes the scoop clean of pebbles and cobble that would interfere with closing. By the same token, removable side plates prevent the lateral loss of sample as scoops close. This well-regarded self-closing sampler uses our patented spring-loaded pinch-pin™ that releases when cable or line slackens. A safety pin replaces the pinch-pin™ when not in use to prevent injury.

Removable screens on top of each scoop allow water to flow through as it descends. This lessens the frontal shock wave and reduces surface disturbance. Both screens are covered with neoprene rubber flaps that close during retrieval. Choose only stainless steel for severe conditions. Ship wt: 67 lbs. Crane and winch recommended due to working weight.
