Water Sampler
No tangled lines with this efficient, economical sampler. A single line deploys and triggers the collection of a 1.5 liter water sample from any convenient depth in lakes, rivers, or ponds. The flow-through design allows a valid sampling for measuring temperature and water quality. A 14 meter line is supplied. NOTE: Volume may vary slightly. It is recommended that you verify the exact volume of your bottle prior to use.

How Clean Is The Water
Water pollution is a major public issue today. This kit allows students to test local water samples for pH, available phosphate, chloride and lead concentration, oil determination and bacterial contamination. This kit will support a demonstration, or small groups, or three repetitions for a single investigator and will require two 45-minute class periods, along with three or four days of observation.
