Parflux Sediment Trap（Mark 78H-21）

Time-series sediment traps were the original McLane Research Laboratories product line when the company was founded in 1983.

Product Description Time-series sediment traps were the original McLane Research Laboratories product line when the company was founded in 1983.

Sediment Traps collect vertically settling particles into individual sample bottles which are sealed when not in collection mode.

Our traps provide exceptional performance for biogeochemical studies including radionucleide, paleoproxy, carbon cycle analysis. They are also beneficial for environmental and pollution monitoring.
