The Cannolator Measuring Cup 250ml is a borosilicate glass beaker designed specifically for use with the Cannolator Cannabis Extractor by Medi-Wiet. It lets you measure your carrier oil down to the millilitre, so your cannabis oil batches come out consistent every single time. If you've been eyeballing quantities with a kitchen jug, this is the upgrade that actually makes a difference to your end product.

This cup is designed to pair with the Cannolator Cannabis Extractor from Medi-Wiet — if you haven't got the extractor yet, grab the Cannolator Complete Set, which includes everything you need to start making cannabis oil at home. Already have the full kit but cracked your original cup? This is the exact replacement part.
Consistency is the whole game with homemade cannabis oil. The Cannolator extraction process works by passing a solvent through your plant material and collecting the concentrated result in a carrier oil — olive oil, coconut oil, whatever you prefer. The ratio of carrier oil to extract determines your final potency. Get that ratio wrong and you're either wasting good flower on weak oil, or accidentally making something far stronger than intended.
A standard kitchen measuring jug gets you in the ballpark, but the markings are spaced for cooking — 50ml increments at best. This Cannolator cup has tighter graduated markings designed for the smaller volumes you actually work with during extraction. When you're measuring out 30ml or 80ml of oil, that precision matters. We've heard from plenty of customers over the years who started with kitchen equipment and switched to purpose-built gear after their second or third batch came out inconsistent.
The borosilicate glass is the other reason this isn't just a fancy beaker. Regular glass can crack when you pour warm oil into it or place it near the Cannolator's heating element. Borosilicate handles thermal shock — it's the same material used in laboratory glassware and high-end coffee pour-overs. Pick it up and you'll notice it feels thinner and lighter than soda-lime glass, but it's actually tougher where it counts. The one honest limitation: borosilicate is more resistant to heat than impact. Drop it on a tile floor and it will shatter just like any glass. Keep it on a stable surface while you work.
Medi-Wiet — formally Stichting Medische Marihuana — is a Dutch non-profit organisation that developed the Cannolator system to give people a reliable, repeatable way to make cannabis oil at home. The Cannolator itself is a small extraction device that uses food-grade alcohol to strip cannabinoids from plant material, then evaporates the alcohol off, leaving you with a concentrated extract. The whole system was designed with simplicity in mind: no lab experience required, no dangerous pressure vessels, just a straightforward process that produces consistent results.
This measuring cup is one of the purpose-built accessories Medi-Wiet developed alongside the extractor. It's sized specifically for Cannolator batches — 250ml is enough for a generous run without being so large that small volumes get lost at the bottom. Every component in the Cannolator ecosystem is designed to work together, which is why we'd always recommend using the matched accessories rather than improvising with kitchen gear.
You can, but kitchen jugs typically have wider increments (50ml+) and are made from soda-lime glass or plastic. This borosilicate cup has finer graduated markings suited to the smaller volumes used in Cannolator extraction, and it handles heat far better than standard glass.
Yes. Borosilicate glass handles dishwasher temperatures without issue. Just avoid abrasive cleaners or scouring pads — they can wear the printed measurement markings over time.
Borosilicate glass contains boron trioxide, which gives it a very low thermal expansion coefficient — roughly 3.3 x 10⁻⁶/K compared to about 9 x 10⁻⁶/K for regular soda-lime glass. In plain terms, it won't crack when you pour warm oil into it or expose it to rapid temperature changes during extraction.
It's made by the same manufacturer — Medi-Wiet — specifically for the Cannolator Cannabis Extractor. The 250ml capacity and cup diameter are designed to sit beneath the Cannolator's collection point. It's the same cup included in the Cannolator Complete Set.
That depends on how much plant material you're processing and what concentration you're after. Most Cannolator users work with between 50ml and 200ml of carrier oil per run. The cup's 250ml capacity covers the full range with room to spare. Follow the dosing guidance included with your Cannolator extractor.
Borosilicate glass is heat-resistant and can handle boiling water temperatures. However, this cup is designed for measuring and collecting — not as a heating vessel. Don't place it directly on a hob or open flame. Use it as directed in the Cannolator setup.
Yes. If you bought the Cannolator Complete Set and cracked or broke the original cup, this is the exact same 250ml borosilicate measuring cup that came with your kit. Same manufacturer, same specs, same fit.
