US WBH-96 Weighted Bottle Sampler

The weighted bottle sampler is a stainless steel metal housing used to secure a bottle for sampling in streams with a velocity too low for isokinetic samplers. Usually an open mouth bottle or a bottle with a US D-77 or US D-95 cap without a nozzle is used. The metal housing has holes drilled near the top for a rope line that is used to secure the bottle and deploy the sampler. It should always be documented that a sample taken with the weighted bottle sampler is not an isokinetic sample.
