100mm Glass Funnel, Short Stem, Borosilicate Glass, Heavy Wall, Karter Scientific 213V12 (Pack of 2)

This glass funnel is perfect for people who want to transfer small amounts of liquid into tiny bottles. I use it for e-cigarette liquid transfer. It works great and it is clear so you can actually see the liquid go into the container you are filling. I highly recommend this to anybody who wants to transfer small amounts of liquid. Being that it's glass, I would recommend storing it in a safe place. Mine hasn't broken but I'm sure it would if I dropped it on the ground.

Finding a quality funnel for oil painting mediums was damn near impossible. Finding a quality small sized funnel was a chore. This little dude is the solution. Now it is not indestructible! But I've have dropped it a few times on my tile floor and somehow it did not break. But I'm not pressing my luck because it is glass! Some of the oil mediums (mixtures of my design) will discolor and likely cross-contaminate plastic funnels and (I also fear) saturate the plastic (making them even more flammable than normal). So glass was the only way to go!

Very cool! Worth the money!

I used this funnel to make my lip balms and am reviewing off of that use only. Do not buy this for that use because the wax, among other products I use, get clogged in the tip. More product got stuck and clogged than what went into the snort chap stick tubes. Complete waste of products, time and money. I'm sure this funnel works great if you only use it with thin liquids. UPDATE: I found a new use for this little guy; I make my own essential oil rollerbottles in 10ml amber bottles. This is perfect for adding a carrier oil into the bottle. Just perfect!

I bought it to use as a wire mold to make a merkabah shape. 50 mm is very small. It will be useful for transferring essences/extracts for example Frankincense, that I use often. It is not useful as a wire twisting mold, although it is tough (I did not break it yet). About big enough to put all of a woman's five fingers inside, smaller than a cocktail glass same shape and might be useful for holding a sphere on top of a pyramid by using the stem as a shaft to pierce a top ball which is then sealed with hot glue. If I clamp it it might break using 14 AWG and smaller wire won't stay either. I'll get a bigger funnel for molding wire into a cone.

was exactly what it said it was, in the answered questions there is an accurate measurement of the stem diameter. the only discrepancy is that the bottom of the stem is angled, which is actually a benefit. some people are saying this thing is flimsy, but I think they were angry because they broke it. this is as solid as you would expect a glass funnel of this thickness, and it has functioned for the past few weeks exactly as I had wanted it to. I use this for pouring my kombucha into grolsch-style bottles and I avoid plastic for health reasons. This funnel is perfect for that, and the price is reasonable considering how difficult it is to find a funnel that isn't a derivative of that stainless steel funnel/strainer combo from china that every company has bought and is trying to resell here.

I go these thinking they would be useful for setting up a gas trap. While I have not done that yet I did discover this was a great size for filling my titration burette. They are smallish and seem delicate. However I've managed to drop them a couple times without breaking them.

Arrived on time and packaged well enough. The first thing that stood out is how ridiculously thin the glass was. It struck me as being the kind of quality I would find at the dollar store, the ID and OD measurements of the stem were off from other measurements given in the Customer Q&A/Reviews, with the ID of the stem being slightly over 1/4" and the OD of the stem being slightly over 5/16" (measured with a digital caliper and rounded down to the nearest reasonable fraction). The stem was not perfectly centered and leaned slightly, and the ground edge on the stem was done fairly cheaply as well and not polished. Also, some of the reviews are almost for sure fake. See if you too can find the one(s) that sound like it was written by a direct representative of the company! Thick glass? High quality? I'm throwing the BS flag! Either these reviewers have vastly different expectations/ideas of what 'thick' or 'quality' glass means or they lie like a rug :). QC doesn't explain it either. I've been through buying cheaper/thinner glassware before and it only seems like a good deal until slowly, piece by piece, the cheap glass breaks in the dishwasher or falls over on its side in the sink and can't survive its own weight, etc. If you, like me, are interested in a higher quality funnel even at a higher cost, then I hereby nominate the Carolina Biological Supply Company as at least one place you can go and buy just one Pyrex funnel, but of substantially higher quality. Very thick, no bubbles in the glass, stem is perfectly centered and ground to a much cleaner edge and polished, looks like it was made with a good mold. Definitely more than twice or thrice as well made, as well as thick. Surprisingly, for being quite a few multiple times nicer, the main additional cost is shipping. Might be worth looking into for some of you. Their site can be found at carolina<dot>com. The product is listed as "Pyrex® Short-Stem, Fluted, 60-Degree Angle Funnel", and then pick the size that is closest to your needs. You're welcome.

Vienen muy bien empacados, igual a lo que se describe

good for filtering

Great item. For Diy e juice, stem Just to thick for normal 30ml Bottles (plastic). works for glass and unicorn Boyles great in 30ml, Also any other bigger bottle sizes. Was not protected that well during shipment. Wasn't broke so no big one

Love this tiny funnel - It's about the size of a pop socket in diameter at its widest, ​and the neck is thinner than a Starbucks tall straw. So useful for working with essential oils and not making a huge mess.

Well built.
