Liquid and Gas Sample Tool

Maximize diver bottom time.

Tooling designed to capture gas or liquids escaping underwater for the purpose of recovery to surface for analysis.

Three tools are offered.

One tool captures high pressure samples of gas or liquid. Sample filling relies on pressure differential between the isolated sea level pressure inside the bottles and the surrounding ambient sea water pressure. This filling operation happens once per bottle, per dive.

Two tools capture low pressure samples of gas or liquid. There is an electrically operated and hydraulically operated version of the low pressure tools. Sample filling is mechanically achieved via a syringe ingesting or expelling the sample whilst submerged for multiple opportunities in case first sample fill was in the wrong location.

Why is Vortex Dredge Superior to other ROV Units?

Vortex dredges have been designed to combine high suction values and high water volumes to tear up sticky soils with very high suction then keep it flowing with high water volume. Powerful, simple, effective.

Example: Getting a "RIDICULOUSLY THICK MILKSHAKE" ® ™ to move through a straw is similar to dredging a very sticky seabed and suction is key because if you drive a suction hose deep into sticky mud the water flow in the suction hose will often stall and the hose is essentially filled with a 'plug' of mud and only high suction will clear the hose. Once the hose is clear then water flow takes over. Suction does the work and water flow continues the work done.

VORTEX performance figures DO NOT have a small print clause with an Asterix symbol next to figures which would represent "best case Scenario" removal rates as opposed to actual removal rates.

VORTEX removal rates are ACTUAL removal rates as seen with actual material moved using Magnetite black iron sand and rocks weighing 2.375kg per liter as to the sample product.
