Tube Sampler

Zone sampler for vertical profile sampling of water from weak-flow containers. The samples is taken in a cylinder with caps on both ends. Before sampling, caps must be secured in open position using a split pin at the end of the string. After submerging the sampler to the required depth, pull the string quickly upwards to free the closing mechanism and close both ends of the sampling cylinder. This will preserve the liquid sample from the required depth in the cylinder. After removing, the sample can be poured in a sample container, or the closed sampler can be hung in suitable place and you may observe the sample sedimentation through the transparent cylinder wall.
