Review: Solid Little Glass Funnels for Small-Batch Work - I grabbed these because I’ve recently been diving into perfumery and fragrance blending, and when you’re working with small amounts of oils or alcohol, a big kitchen funnel just doesn’t cut it. These 50mm short-stem funnels hit the sweet spot — small enough for precision work, but still sturdy enough to survive real use. ⸻ Build Quality They’re made from borosilicate glass, so they can handle both temperature changes and exposure to alcohols, essential oils, and other solvents without clouding or reacting. The glass walls are noticeably thick for their size, giving them a nice heft and a feeling of durability. ⸻ Design & Functionality The short stem is perfect when you’re working with shallow containers or small bottles — it won’t get stuck against the bottom and cause liquid backup. The mouth is wide enough for steady pouring, but not so wide that you lose precision. I’ve been using them to transfer diluted fragrance blends into smaller vials without spills, and they’ve been mess-free so far. ⸻ Ease of Use & Care They rinse clean easily — even with viscous oils — and being glass, there’s no lingering scent contamination like you’d get from plastic. For perfume work, this is huge, because residual scents can ruin your next blend. I usually wash them with warm soapy water, rinse, then air dry, and they’re spotless. ⸻ Pros: • Thick, durable borosilicate glass • Short stem ideal for small bottles/vials • No scent retention, perfect for fragrance work • Comes as a 2-pack — backup or multi-tasking Cons: • Small size means they’re not great for larger-volume transfers • Being glass, you still have to be careful not to drop them on hard surfaces ⸻ Final Verdict: If you’re into perfumery, essential oils, tinctures, or any small-scale liquid work, these are perfect. Sturdy, well-made, and the right size for precision without wasting product. At this price for two, it’s an easy win.

## Questions & Answers

**Q: What size (diameter) is the neck?**
A: Hi, Kenney. In the reviews below, David Gailes entered some specifications for this item, and he put the neck diameter at 1/4 inch externally, 1/8 inch internally (ie, the exit hole would only be 1/8 inch). I don't have very precise measuring tools on hand, I'm afraid -- in fact, I only have an old and rather beat-up wooden ruler -- but from what I can discern using that ruler, Mr. Gailes' measurements look good to me.

**Q: I need a small metal or glass funnel to fill (pill) capsules size 00. Would this work for me? Thank you!!**
A: The outside diameter of the stem is 6 mm so it should fit into the 00 capsule which has an inside diameter of approximately 8 mm.  However, the bevel on the stem is >7 mm so I don't know how much material you can deliver into the capsule.  One option might be to cut the bevel off to flush.

**Q: Where are these manufactured? Trying to avoid China...**
A: This item is manufactured in China.

**Q: What is the ID and OD of the stem of the funnel?**
A: OD 9.92 mm or .390 inchID 6.82 mm or .268 inchMeasured with digital calipers
