Pulsar Bamboo Sifter Box

Open the bamboo lid and place the 125-micron sifting screen over the dark glass collection tray. Load your herb, trim, or cured flower onto the top surface of the sifting screen. Close the bamboo lid over the screen and shake the box gently for several seconds, allowing gravity and movement to pass the finest trichome particles through the mesh and into the glass collection tray below. Open the box, remove the screen, and use a scraper or small brush to collect the pollen that has accumulated on the dark glass surface. The dark glass makes it easy to see and collect even small amounts of kief.

The Pulsar Bamboo Sifter Box Small measures 3 inches by 5 inches, and the Medium measures 4 inches by 6.5 inches. Both sizes use the same 125-micron sifting screen, dark tempered glass collection tray, magnetic closures, and finished bamboo construction. The Medium provides more sifting surface area, which allows processing of larger quantities of herb per session and accumulates kief more quickly for high-volume users. The Small is better suited for personal use, travel, and discreet storage. Both sizes produce equivalent kief quality.

Kief is a pale, light-yellow fine powder that can be difficult to see and collect on light-colored or transparent surfaces. The dark-colored tempered glass tray creates high visual contrast against the pale kief, making even small yields clearly visible and easy to gather completely with a scraper or brush. Tempered glass is chosen because it is smooth, non-porous, and easy to clean, and it does not retain odor or degrade over time with repeated isopropyl alcohol cleaning. A scraper tool glides smoothly across the glass surface, allowing users to collect all of their kief without any material sticking to the surface.

Most 4-piece herb grinders with kief catchers use screens in the range of 100 to 150 microns, which is similar to the 125-micron screen on the Pulsar Bamboo Sifter Box. The key difference is the sifting method and scale. A grinder kief catcher collects kief passively as a byproduct of grinding, in small amounts per session over time. The Pulsar Bamboo Sifter Box actively sifts herb or trim in a shaking motion, processing larger quantities at once and producing more kief per session. The sifter box is also better for processing uncured or unground herb, trim, and dried material that cannot go through a standard grinder.

Yes. The Pulsar Bamboo Sifter Box is well-suited for sifting trim, loose leaf, and cured flower alike. Trim — the small leaf material removed from cannabis buds during harvest — typically contains a significant concentration of trichomes and can be sifted in the bamboo box to collect kief that would otherwise go unused. For trim sifting, a gentle shaking motion over a longer period produces more thorough trichome separation than a few quick shakes. The dark glass tray makes the accumulated kief visible even when starting from loose material with a lower trichome density than cured flower.

Detach all three sections by separating the magnetic connections. Use a scraper or small brush to collect any remaining kief from the tempered glass tray before cleaning. Soak the sifting screen and glass tray in isopropyl alcohol for 10 to 15 minutes to dissolve residue, then brush clean, rinse with warm water, and dry completely. The bamboo lid should be wiped clean with a damp cloth rather than soaked, as prolonged water exposure can warp bamboo. Avoid harsh abrasive materials on the glass tray surface. Reassemble once all parts are fully dry.
