The Mini Auto Siphon is perfect for those small fermenters where a full sized auto siphon can be too large. This siphon will work great for 1 and 2 gallon sized fermenters. Simply insert the auto siphon into your fermenter or carboy, push down on the racking cane (included) and a siphon is started. The tip on the racking cane is slightly larger than normal, which filters out a lot of the sediment during transfer. Disassembles easily for cleaning and sanitizing. Uses 5/16" or 3/8" siphon tubing (not included).
