Qnubu Autosift screen: choose the exact micron for your dry sift
The Qnubu Autosift electric vibrating sifter separates resin from flowers automatically, and its result depends on one thing: the mesh. With the Qnubu Autosift screen you can fit your machine with the mesh you need at every stage, available in 40, 70, 90, 120 and 180 microns. Each mesh size gives a different kind of extraction: maximum purity, balance or higher yield.
Which micron to choose
The resin passes through the screen and the plant matter stays on top. The finer the mesh, the fewer particles get through and the purer the extraction; the wider it is, the more you get in less time.
| Screen | Type of extraction | Best for |
|---|---|---|
| 40 µm | Ultra-fine selection: only the smallest, most resinous particles pass | Those after maximum purity who accept giving up some quantity |
| 70 µm | Balance between quality and yield: clean, aromatic and stable extraction | The most versatile option for most growers |
| 90 µm | More throughput without losing definition, with good organoleptic quality | Those wanting a bit more volume while keeping a good finish |
| 120 µm | Generous production: more quantity in less time, with a more plant-like profile | Those who prioritise quantity |
| 180 µm | Fast, wide-grain filtering: lets even coarser material through | Large volumes and pre-filtering where yield comes first |
How to get the most out of them
Having several screens lets you adapt each session to your priority. A common method is to work in two stages: a 180 µm pre-filter to quickly separate most of the resin, then a finer screen (70 or 40 µm) for a more select fraction. Keep each fraction separate: you’ll have one resin of maximum purity and another with more quantity.

Tips for use
- Dry, cold material: moisture clumps the resin and clogs the mesh; a few hours in the freezer help trichomes break away.
- Don’t overload the screen: the material needs to move with the vibration.
- Collect the first fraction separately: the first minutes give the cleanest resin.
- Cleaning: after each session, clean the screen with isopropyl alcohol and let it dry completely before refitting.

FAQ
Does it fit other machines?
No. This screen is designed for the Qnubu Autosift electric vibrating sifter.
Can I use it by hand, without the Autosift?
It’s designed for the Autosift, where it gives the most consistent result. Like any framed screen, you can also sift by hand: gently rub or shake the material over the mesh, with a tray or baking paper underneath to collect the resin.
Which micron should I get if I only buy one screen?
The 70 µm is the most versatile: a balance between purity and quantity. If quality is your priority, choose the 40 µm; if volume is, the 120 or 180 µm.
What is the 40 micron screen for?
It’s the finest in the range: it only lets the smallest, most resinous particles through. It gives the purest extraction, in exchange for less quantity.
How do I clean it?
With isopropyl alcohol. Then let it dry completely before use: a clean, dry screen lets resin through far better.
