The standard Dopak DPM sampler in system purge configuration ensures the retrieval of a representative and contamination free sample.
This system is now available in a NEW configuration with a flexible dip tube and submerged pump. This new arrangement allows for sampling of liquids from the top of large vessels (with or without agitator) where insufficient vacuum can be created to lift the liquid from the vessel.
So, if you need to take contained liquid samples from tanks/vessels with insufficient vacuum source available then please request details of the Dopak DPM sampler c/w dip pipe & submerged pump.
