Questions & Answers
The word "disposable" comes up frequently in their description. You'll be lucky if you can use them even twice. After only three or four times of being squeezed, the top seam spits. I think they'd be better if they were a little more powerful, but, as I previously stated, these droppers are disposable.

These work well with thin liquids like water, but they won't work with anything thicker. It did not work with vegetable glycerin, but it does well with liquids such as water.
I bought these to use in art projects where I needed to drip alcohol onto ink. They effectively absorb liquid and, in most cases, do not allow it to drip out in an unintended location. The droplet is relatively simple to manipulate. Later, I needed one to measure liquid medicine for a cat, so the volume markings on the side came in handy; overall, the price was reasonable, and they did exactly what I needed.
These were given to me as part of a chemistry set that I purchased. Although it was created ten years ago, it was almost never used. It had been in the garage for a while, but I recently got it out. Make a cleaning plan. Complete all of the 400 experiments that came with the set, as well as those from an Advanced Chemistry book I purchased on Amazon. Obviously, medicine droppers aren't required for all of the experiments, but I didn't want to spend the money on a more expensive set. a set of droppers that costs a lot of money Then there's the matter of rinsing them. These disposable ones are ideal for my requirements. I was taken aback by how long it took. They're quite large! They're a minimum of 6 inches long. Obviously, it holds far more liquid than a standard 4" dropper. They are, once again, disposable. So, with a hundred of them, I should be able to complete all of my relevant experiments without difficulty. When you need disposable medicine droppers, this product is HIGHLY RECOMMENDED!.
The simplest droppers are these. The tips are all ragged from the molding process, but this can be fixed by cutting a small section off with scissors. They're graduated (with a 1/2 ml mark and 1 ml marks up to 3 cc), but they're not particularly accurate. And they're basically the same thing. They don't come apart for cleaning, so they're only good for a limited amount of time. br>br>However, they're exactly what I was hoping for. They do what I need them to do (give me a way to measure small amounts of airbrush paint so I can duplicate similar mixes later), and they're inexpensive. I gave them three stars because I've seen other droppers with less ragged tips and less shape variation.
This product was used to make thin resin for use in molds. I, on the other hand, refused to take it. I went ahead and tried another, assuming the first had failed. I tried six times in total and received no results. Water was also ineffective. Just not a well-made product; I bought the same pipettes at a craft store, which were a little more expensive but worked perfectly. It's not uncommon for items to be out of stock.
These were purchased for the purpose of filling lip balm tubes. For what I needed them to do, they were ideal. Plus, there are so many that I won't have to buy any for a long time! For the quantity, this is a fantastic deal! Thank you very much!.
For my herbal needs, these are ideal disposable droppers. They're what I use to add oils to custom orders and to make sample tinctures. I'm not a big fan of using something once and then throwing it away or recycling it, but when it comes to herbal supplements that people might ingest, you don't have a choice.
I feel a little bad buying 100 of these when I'm only going to use a few, but they're great for adding paint or subtracting excess paint from my acrylic pours. You can see me demonstrate them on my YouTube channel AVA Art (Aerial View Aesthetics):.
