The size of our plates on our handheld unit guarantees that 80% or more of the surface area is used in each press. This causes the rosin and wide variety of terpenes to exit the plates to a cool, safe zone immediately. In combination with our unique sloped design and heating process, this makes temperature control unnecessary. Once pressure is locked in, and the unit is powered on, the plates will heat from room temperature to 250 degrees. Each terpene melts at a different temperature and will be pushed out one at a time outside the plates, this allows for the highest-quality rosin and maximum yield with only one press!The Ju1ceBox Tabletop Twist Rosin Press was specifically designed for commercial purposes considering the huge demand of rosin or concentrates. The built-in temperature control allows each press to be adjusted between 160’F and 350’F.
