This is a sampling device, which enables you to draw off a small quantity of fermenting beer, wine, cider or spirits, to test the gravity. It's easy to sanitise and simple to use and is narrow enough to be easily used with demijohns. To use, first sanitise, then dip into the liquid to be tested. Place your thumb over the open end, and lift out. Place pipette inside trial jar and remove your thumb, to allow the liquid to flow out of the pipette.
