With the 'Rosin Bag Filters' from Oil Black Leaf®, the production of the finest, exquisite smoke oil extracts is very easy. If you use the nylon filters for extraction using the so-called 'rosin technique', the result is the purest, high-quality concentrate, as the nylon bags reliably filter out all plant residues during the extraction process.
In the 'Rosin technique', green plant parts, flowers or pollen are packed in baking paper and pressed in a heated rosin press with strong pressure at a temperature of approx. 70°C to 120°C or 158°F to 248°F (depending on depending on plant type) pressed for a few minutes.
If you first fill the material to be pressed into the 'Rosin Bag Filters' bag, then wrap it in baking paper and then place the package in the hot press, you will get the desired, precious and absolutely pure concentrate in no time at all thanks to the additional filtering. It is called 'Rosin' and as a concentrate it has a more intense and stronger effect than the starting material. The 'Rosin technique' itself is completely harmless, there is no risk of explosion due to the use of butane gas or chemical solvents.
The 'Rosin Bag Filters' have a non-stick inner coating so that the sticky plant residue that remains can be easily removed from the filter bag. The extraction process can be repeated up to four times, depending on the desired level of purity. The 'Rosin Filter Bag' is made of a special nylon fabric, which is particularly heat-resistant (up to 240°C/464°F), robust and reusable. The 'Rosin Bag Filters' are available in different sizes and mesh sizes, depending on the amount and type of raw material used.
