GRAVEDA BottleTech PrePress

The 4-piece Bottle-Tech PrePress weed-tobi from Graveda was invented by a loyal Graveda customer, namely Tobi. It has quickly established itself as a legendary and useful tool in the field of 'rosin production' (i.e. production without the use of solvents). This is because this manual pressure press for the bottle tech method optimizes the green material as a pre-press before actual pressing with a hot pressure press.

✔️ Ideal preparation for hot-pressing the finest rosin

✔️ Increases purity, strength & yield of the extract

✔️ Milled from 3 robust, durable, already recycled & recyclable aluminium blocks

Equipped with a rosin filter bag measuring 51 x 89 mm (turn it inside out, fold the ends over, ... - better watch a video on the net), you can press small, compact, perfect packets of herbs wrapped in filter paper without any effort on your part.

This reduces the material's footprint prior to pressing, which pays off later. This is because compressing the material by one millimetre increases the pressure per square centimetre. This, in turn, increases the yield, strength, and purity of the rosin. The uniform packets of herbs are then pressed into perfect rosin by a hot-pressure press, ensuring they are pressed totally even thanks to the pre-treatment.
