Single dosing on the Eureka Atom

The Atom is sold in several burr sizes and the range matters here. The Atom 60 runs 60 mm hardened steel flat burrs with a removable hopper holding around 510 g. The Atom 65 steps up to 65 mm. The Atom 75 uses 75 mm burrs — the same size Eureka fits to the Olympus and Mythos — behind an 800 W motor running at about 1650 rpm. All of them share stepless micrometric adjustment, timer-based dosing and Eureka’s sound insulation.

What they also share is a hopper designed to sit full of beans. If you grind one dose at a time, that is capacity you are not using and beans you are letting stale. This blow-out hopper takes the stock hopper’s place so you can weigh in a single dose, grind it, then press the silicone bellows to push grounds out of the burr chamber and chute.

Switching coffees without a purge shot

Timer dosing on the Atom assumes a consistent bean feed. Once you single dose, the grounds left behind between doses are what throw the next one off. Clearing them with air is quicker and cheaper than sacrificing beans to a purge.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
