AS ONE PTFE Groundwater Sampler Mini Type

This sampler pumps groundwater etc. from a pipe or thin pipe with a minimum diameter of 1.5 cm.
It is made entirely of PTFE, with a body outer diameter of 1.2 cm and an inner diameter of 0.8 cm.
The top has an open structure, and the holes on the top left and right for passing the hanging wire are 4mm in diameter.
The tapered insertion type bottom is designed to minimize leakage of the sampled water even when the sampler is pulled above ground.
When the sampler descends, the sampled water enters and leaves the tube through the upper and lower holes, and when it ascends, the ball inside the bottom blocks the bottom hole, making it difficult to discharge. Therefore, it is not suitable for sampling water from springs that contain debris, etc.
Individually packaged in plasticizer-free polyethylene bags, they can be used immediately after opening.
