Sampler, Wading Type, US DH-81

The US DH-81 is most commonly used for trace metal, biological or sediment sampling during normal flow in small to intermediate-size streams or through ice. It uses the US D-77 cap that has an internally molded vent tube and all parts are autoclavable. This construction enables the sampler to be used for collection of depth-integrated samples for bacterial analysis.

The DH-81 is useful for sampling during cold weather because the plastic sampler head and nozzle attach directly to the bottle, eliminating a metal body and a sampler-freeze up condition. The DH-81 uses a quart-size glass container and a standard wading rod that is ordered separately. Nozzles are available in 1/8 inch (3.2 mm), 3/16 inch (4.8 mm), 1/4 inch (6.4 mm), and 5/16 inch (7.9 mm) diameter sizes.

The DH-81 includes a DH-81A adapter, D-77 cap, 1/4 Plastic nozzle and 1 Qt-size Glass Bottle. WADING ROD IS SOLD SEPARATELY
