About Van Veen Grab Sampler

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 mudsedimentsludgedeposit samples from the bottom of rivers lakes ponds shallow seas etc

The simple design means it is simple to use Heavyduty hinges and the hinge pins can absorb thousands of bottom impacts Selfclosing scoops have center 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 cobbles that would interfere with closing By the same token removable side plates prevent the lateral loss of sample as scoops close This wellregarded selfclosing sampler uses our patented springloaded pinchpin that releases when cable or line slackens A safety pin replaces the pinchpin 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
