Yes, the droppers work with any size essential oil bottle I've tried. I've used them in a 5ml bottle, a 10ml bottle, and a 2 oz bottle. As a result, they should fit into a 1/2 oz (15ml) bottle.
I'm not sure how I feel about the enamel. Yes, you can use acrylic paint, but you might want to cut the end off to make the hole bigger. If not, because the initial hole is small, it may take some time for it to get into the tubing.
For $3, there were 20 items in the order.
Yes and no; they can be reused if the part where your thumb squeezes isn't accidentally broken. It's not a silly question at all:

br> They're a little dripping, but they get the job done. They're very cheap. br>They're also a lot longer than I anticipated (6. 1"). Depending on your purpose, I suppose that could be a pro or a con. br>br>Contrary to popular belief, there are a number of disadvantages to using this product. They aren't sterile, and you can't measure accurately with them. The pipette has a visible seam that runs the entire length of it. One of mine had a crack in it. br>br>Though the title description says "20 pieces," the secondary description says "pack of 100. " From a bag of 100 pipettes, you'd almost certainly get 20 unwrapped pipettes.
I was extremely dissatisfied because I had already gone through seven droppers, all of which broke after just one squeeze. The bladder shattered right at the seam. My samples were tainted, and I had to start from the beginning. I stopped using the word "remainder" because it was taking up too much of my time. Given that this product is advertised as being of research-grade quality, I believe that a 7 out of 7 failure rate at the same location indicates poor quality and is inconsistent with the product description.
Hey, they're great for what they're made of and for the price!
- You ain't gonna get absolute precision and all the other bells and whistles in ANY *inexpensive* single-channel audio system. (or a small number of) Pipette is a word that has a lot of different meanings. You get what you pay for, and there's no point in crying because the cheapest option isn't as good as the most expensive option. a high-cost item analog in terms of technology
- BUT, if you only need to transfer a small amount of liquid (up to 3 ml with this model), this is a good option. well- Adhesives, oils (botanical OR mineral), peroxide, lye solution, or whatever are used in small amounts and have good chemical resistance, material release, and are low-cost. They're also low-cost and high-quality. It is simple to use.
- They go so far as to take- BSI 30-thick Epoxy components 5-minutes and BSI I didn't think they'd be able to handle it, which is why I only bought a small package in the first place. They're also "non-" Though it takes a little practice, you can "stick" and "let go" of the viscous resin and hardener.
- The take-out container is ideal for "normal" liquids. Of course, getting up and letting go is a lot easier;.
However, the prospect of purchasing a plastic item that will end up in the trash after a day or two of use does not appeal to me. It's a pity that similar non-profit organizations aren't able to help. All of the disposable items appear to be either small or 7" in length. They do the job for a while, but they're not very useful as an art tool in the long run - It's simply too delicate.
Weed killer can be applied using this tool. I bought these droppers so that I could apply weed killer to specific areas (i. e. , so that the liquid only hits the weeds and not the plants you want). I've had no problems with the quality, and I've been able to use just one dropper for months. Because the liquid would never come out unless the bulb was squeezed, I was overjoyed. My only suggestion is to sell them in smaller quantities.
These are effective in their current state. I used them to make lip balm. I was glad I got a lot of them because the balm congealed in there if I slowed down, so I put it aside to throw away and grabbed another one. They didn't like the temperature of the double-boiled liquid, so I knew I wouldn't be able to clean them when working with oils and butters. If the tips were in contact with the liquid for more than a few seconds, they would bend, and one of them appeared to have a hole in it. So they should be fine for cooler situations, but they're a little flimsy. Also, they don't hold up well in hotter temperatures. For warmer projects, I'll look for something with a thicker wall. That price, on the other hand, was what got me started.
Despite the fact that these are disposable, they only lasted a few minutes each. I had them fill 10 ml bottles with cool essential and carrier oils, and after only a few bottles, each of these droppers split along the seams where you squeeze them. I would only recommend this product to someone who requires it for a single, very limited use.
I had no trouble controlling the droplets. I don't normally purchase disposal plastics because I despise waste, but pipettes are extremely difficult to clean. As a result, the simplest option is disposable. I'm going to place another order!.
