Fill it with rinse-free sanitizer (starsan, iodophor or hydrogen peroxide). Place the bottle over it in an inverted position, and press the spring to sanitize the bottle. Place it in the dryer for the excess sanitizer to drain away and you are ready to bottle and seal. This time-saving device is a must-have for those with large batches.
We can fit it on top of the bottle tree dryer to save space and for convenience. For more details refer to this step by step instructions
It is also called Vinator, Sulphiter and Avvinatore Lux.
