The Mighty Gripper is a unique piece of equipment - recognised world-wide as being the best sampling device available. The uniqueness is in the fact that water or other liquids are sampled directly into the bottle that will go to the laboratory. There is no decanting from collection container into final bottles so no chance of cross contamination. They are also autoclavable for sterilizing purposes. The equipment is mainly used for water sampling from rivers, streams, dams, ponds etc. They are also used in industrial situations for sampling chemical strengths and dilutions in vats and holding tanks.
