The Graveda Rosin Bags (51 mm × 89 mm) are premium-quality filter bags designed for solventless rosin extraction. Made from durable, heat-resistant nylon mesh, they ensure clean, efficient yields and are available in multiple micron sizes — each suited to different materials and extraction goals.
These bags are known for their exceptional build quality and resistance to blowouts, even under high pressure. Perfectly sized for most standard rosin presses, they offer consistent filtration and maximum terpene and cannabinoid preservation.
Choosing the right micron size:
-
25–37 µm: Ideal for dry sift or bubble hash, offering maximum filtration and purity. Produces the cleanest, terpene-rich rosin with less yield.
-
73–90 µm: Best for ice water hash or finer material, balancing yield and clarity.
-
120–160 µm: Great for pressed flower, allowing optimal flow of oils while keeping plant particles out.
-
190–220 µm: Suitable for larger flowers or fresh-frozen material, maximizing yield with less restriction.
No matter your method, Graveda Rosin Bags provide reliability, precision, and quality you can count on.
