Water Samplers
 | | Van Dorn Water Sampler |
The Van Dorn Water Sampler, available as either horizontal or vertical models in capacities of 1L, 2L and 3L. They are available with either transparent or non transparent bodies. The devices are messenger operated.
The Marpet Water Sampler has a capacity of 500ml. The bottle holding the water sample can be removed from the sampler body once the sample has been obtained, and replaced with another bottle. This alleviates the necessity to decant the sample immediately after it is taken. This means that the design is ideal for obtaining multiple samples. The device is messenger operated.
