Rienar White 3ML Disposable Plastic Eye Dropper Set Transfer Graduated Pipettes (20 PCS)

Pros:They work. They drip a little, but they work.They're super inexpensive.They're much longer than I expected (6.1"). I guess that could be a pro or a con depending on your purpose.Cons:They're not sterile.You can't accurately measure with these.There's a visible seam running the length of the pipette. One of mine cracked at the seam.The title description reads "20 pcs", but the secondary description reads "pack of 100". You would definitely receive 20 unwrapped pipettes likely coming from a bag of 100 pipettes.

- Hey, for what they are, and for the price, they work great! - If you want absolute precision and all the other bells and whistles, hey, ya ain't gonna get that in ANY *inexpensive* single-use (or few-use) pipette. Ya gets what ya pays for and 't'ain't no sense in cryin' when the least-expensive option possible does not work exactly the same as the super-expensive high-tech analogue. - HOWEVER, if you want something for transferring small (up to 3 ml with this particular model), reasonably-well-measured amounts of adhesives, oils (botanical OR mineral), peroxide, lye solution, or whatever, these have decent chemical resistance, good release of material, and are low-cost. They are also super-easy to use. - They even take-up thick Epoxy components (BSI 30-Minute and BSI 5-minute, to be exact), which I actually did not expect them to be able to handle, which is why I only bought a small package to begin with. They also are "non-stick" and "let go" of the viscous resin and hardener, though it does take a bit of doing. - For "more normal" liquids, the take-up and release are, of course, much easier ;)

I was extremely disappointed that I have gone through 7 droppers that broke immediately after one squeeze. Broke right at the seam in the bladder. Contaminated my samples and had to start over every-time. I stopped using remainder. As this product is described as being research grade quality, I think a 7 out of 7 failure rate at the exact same spot is indicative of bad quality and not in line with the product description.

These work as what they are. I made lip balm with them. I was glad I got a lot of them because if I slowed, the balm congealed in there and I set it aside to throw away and grabbed a new one. They did not do well with the temperature of the double boiled liquid so I knew cleaning them was not an option when dealing with oils and butters. The tips would bend if in contact with the liquid for more than a few seconds and I did seem to get a hole in one. So they should be fine for cooler matters but are quite flimsy. And do not stand up to higher temps. I will be looking for a thicker walled product for warmer projects. That price though, it got me started.

I bought these to experiment with mixing stains to make and match colors. I bought these because they were the cheapest; they're going to be throwaways anyways, so I can't justify putting much money into it right now. So far, they work...okay. They hold a few drops, and can dispense a few drops...but not much beyond that. They split right along the seam of the bulb after a few squeezes, making them useless.

I use these for putting essential oils into capsules They are really handy moving the oils without spillsVery cheap and very useful! I label the eye droppers so that I can use them repeatedly for the sameoils.

While I understand these are disposable, they didn't last more than a few minutes each. I ordered them to fill 10 ml bottles with cool essential and carrier oils, and after filling just a couple or 3 bottles, each one of these droppers split on the seams where you squeeze them. I would not recommend this product unless someone just needs them for a single, very limited use each.

These are great! Very soft & pliable but still durable. My young child LOVES these& takes every opportunity possible to use them to "suck up" (her words!) Anything. Usually water. Once she played outside with a handful of these & a bucket of water. She was SO happy& played SO long!!
