Siphon with telescopic tube and valve.

By adjusting the length of the tube, the siphon can fit many different fermentors. A 15 mm high anti-sediment tip leaves the bottom sediment behind (unless the fermentor is tilted). A mounting clip to secure the siphon to the fermentor is sold separately.

The vessel to be emptied is elevated so that it's bottom is above the the receiving vessel. Start the flow by filling the hose by sucking on it.
The flow can be regulated by turning the adjustable valve.

Use a suitable cleaning agent / disinfectant when cleaning. Do not use hot water.
