Until the tank is full

.

Start the pressurization and open the pressure regulating valve to allow water to flow into the high pressure chamber chassis to just overflow.

Place the sample without wrinkles on the rubber ring in the water collector, overflow excess water to ensure no air bubbles in the clamp; cover the upper pressure plate and evenly clamp the sample.
