USGS Frame Bag Sampler w/Slotted Bottle, 4L

The Frame-Bag Sampler uses a collapsible bag that is placed in a special slotted 4 or 8 L bottle with a US D-77 cap and nozzle assembly in which the vent is plugged. The slotted bottle is held in a Stainless Steel frame to which various sizes of sounding weights can be attached. The size of the weight depends on the stream velocity along the cross section that will be sampled. The advantages of the Frame-Bag Sampler over the D-77 Bag Sampler are that the Frame-Bag Sampler can be used to collect a larger sample volume and, therefore, to sample greater depths. It can be used to collect samples in streams with greater velocities because heavier weights can be attached to maintain proper orientation of the sampler in the stream. Bag and sounding weight ordered separately.
