Water Sampling

Ghost wipes are essential for the water sampling process. This heavy-duty wiping tool cleans rough surfaces thoroughly before dissolving in the lab for a complete dispersal of analytes. The lack of fibrous material in the wipe allows for clean and precise sample intake. Zefon International carries multiple ghost wipe options, all excellent for water sampling.

HotBlock is another highlight of our water quality sampling equipment. The HotBlock can hold up to 54 water samples at once and digests them before metal determination. HotBlock features high-quality racks that facilitate the loading and unloading of water samples. Check out the Zefon International HotBlock offerings today.

Once you bring your sample to volume and insert a filter, the tool lets you analyze it. Our FilterMate is available in packs of 100 and works in most laboratory setups.

FlipMates digest GhostWipes. They also provide optimal filtration for your water samples. Zefon International offers a pack of 100 FlipMates for your water sampling needs.
