ULAB Scientific Glass Funnel 100mm, Stem Diameter 13mm, 3.3 Borosilicate Glass, Heavy Wall, Pack of 1, UGF1002

Sometimes (a lot of times) i procrastinate cleaning bottles so this is good if i wanna put protein powder in a dasani water bottle.

This is the perfect size to refill 4+oz Boston bottles. The stem is too wide for the mouth of smaller sizes. I decant quite a bit of zeolite on a regular basis, along with soda ash, shampoo, melted shea butter, etc. Plastic funnels have a way of grabbing onto anything, causing clumping and waste. This funnel eliminates that issue. Materials roll off it efficiently. Also, if you have allergies, this is the best option out there as it's plastic&nickel free and easily sterilized&cleaned. It's very high quality and seems resistant to scratches so it appears that it will wind up being very durable over time. The higher thickness of the glass means dropping it is less likely to break it. I accidentally gave it quite a smack with a sauce pan and was certain I had broken it. Nope! I haven't tested it at temperatures beyond probably 125°F so can't speak to it's performance that way. It was packaged very carefully and arrived in pristine condition before the original estimated date. Very pleased with this purchase.

Nice thick glass holds up well. It's a lot bigger than I expected. I thought the stem going down would be shorter and thinner but it works fine.

Just right for pouring paints and coatings, easy clean up!!!! Have not broken one yet, but if I do I think they are good quality so I'd buy them again.

The wide tube diameter allows for well-blended fruit. If something clogs the pipe, blow on the opposite end to clear the jam.

It admirably condenses dispersed flow through a single orifice.

This shipped quickly and was true to description. It’s perfect!

Well made good glass
