Water Samplers

Horizontal Beta Water Samplers

Intended for shallow or deep waters, these bottles are called “horizontal” because they descend, parallel to the bottom. They are ideal for sampling at the thermocline, at other stratification levels, or just above the bottom sediments.

Horizontal Alpha Water Samplers

Vertical Beta Water Samplers

Use vertical bottles in mildly corrosive water, marine water and water with large amounts of suspended solids or adhesive colloidal solids to collect plankton and floating sediments. The wide mouth collects a true water sample with no contamination from other water levels.
