GRAVEDA Rosin Bag Filter Bags

GRAVEDA's precision-manufactured rosin bags, which are specially designed for use with rosin presses (such as the Graspressos from GRAVEDA), maximize the quality of the extracts. Made from heat-resistant, high-strength material, the bags have micron-precise mesh sizes to ensure an optimum flow rate and filtration. The result is pure, consistent and high quality extracts, utilizing every gram of the source material.

✔️ More extraction quality

✔️ Every gram of the source material is optimally utilized

✔️ Optimum flow rate & filtration

✔️ Heat-resistant, high-strength & reusable

✔️ Available in different mesh sizes

The mesh size of Rosin bags is specified in microns. A micron is one thousandth of a millimetre. The smaller the micron size, the finer the sieve and the purer the extract (also depending on the source material, of course). Here is a brief overview of which micron size is best for which material:

5 Micron:
Optimal for: mechanical separation of waxes from terpenes.
Why? These ultra-fine sieves enable a very specific separation, ideal for advanced extraction processes.
15 Micron:
Ideal for; production of THC-A.
Why? This size is specially optimized for filtration during THC-A production.
25-35 Micron:
Ideal for: finest materials such as bubble hash or dry sift.
Why? These fine sieves prevent small particles from passing through the sieve and mixing with the rosin.
72-90 Micron:
Ideal for: general hash extractions and high-quality flowers.
Why? These sizes offer a good balance between flow and filtration, resulting in a pure cannabis concentrate.
120-220 Micron:
Ideal for: fresh cannabis flowers and optimum yield.
Why? When processing flowers, it is less likely that fine particles will get through the sieve. A coarser sieve enables a better flow and yield.
