AS ONE PE Disposable Groundwater Sampler, 300mL, Pack of 24

This disposable sampler pumps water from holes, pipes, boreholes, wells, observation wells, etc. with a minimum diameter of 5 cm.
It is also suitable as a simple water sampler for drawing water from large sources such as reservoirs, ponds, lakes, and dams.
The clear polyethylene terephthalate (PETG) body with a 4cm outer diameter allows for visual observation of the sample, amount, suspended state, and floating matter. It contains a black polyvinyl chloride (PVC) ball, and the top and bottom caps of the body are made of white polyethylene (HDPE), with no weight inside.
The upper part of the body is shaped to make it easy to tie wires.
When the sampler is lowered, the internal ball floats inside the body, allowing the sampled water to flow in, and when it is raised, the ball blocks the lower outlet, making it difficult for the sample to be discharged.
The bottom outlet diameter is 1.5cm, so it is not suitable for collecting water from springs that contain debris.
After lifting, inserting the included polyethylene discharge tube into the bottom discharge outlet will lift up the blocking ball, allowing the sampled water to be easily removed.
No adhesives or oils are used in the manufacturing process, and after completion, the products are washed with detergent and deionized water, dried in a drying room, and then individually packaged in plasticizer-free polyethylene bags, so they can be used immediately after opening.
Returns are not possible once the product has been opened.
