The end of this Nasco Swing Sampler allows collection from different angles, including 90°. The unit is designed for easy sample collection from horizontal flowing streams, such as lakes and sewers. The sampler features an adjustable length fiberglass pole and a bottle held in place with a plastic snapper ring and an adjustable locking device. Other types of bottles can be attached to the sampler, but different fastener types may be required to hold them in place.
