It looks like the printing is printed on the surface of the glass, since it's raised up from the surface. IMHO, if you were to submerge only the tip of the bottle in the oil, this would not allow the graduation to reveal itself.
A rubber that is cheaply made in China is not likely to be safe to eat. As a result of the manufacturing process, the bulb has a seam around its center. This is a ridge, maybe 1mm high, around the inside and outside of the hole. Rubber dust will settle into your food or product if the rubber bulb is squeezed too hard or is squeezed and rubbed together or liquid is sucked into the rubber bulb. If the rubber bulb is not filled with extra liquid or food or cleaned well, it would be okay.
I can confirm that the measurements were A thick enough material can be used for its purposes. The pipe I dropped onto the floor did not break when I dropped it.
There are 12 inches between the rubber bulb and the end of the handle I love mine because they reach into gallon jugs for mixing I keep one just for my pH recovery Periods. He is someone I recommend to anyone who is interested in pHs and mixes. My sister loved hers just as much as I loved hers, so I gave them to her.

As far as construction is concerned, it is a quality item. However, what I dislike most about this design is that it can't hold any liquid inside (no matter how much or how little) while holding it tip-tight. Turn the page. If you try to drop 100% bleach or 91% isopropyl alcohol in a small area, you'll find this very frustrating. I would just be a ding-dong if I were just a ding-dong I don't know a simple trick that I should know about Dong and one that I shouldn't ignore -- In any case, I would be glad to update the rating, but I can't keep it tilted at the tip or plug the end. The liquid spills out every time I try and I have not found an effective way to keep it from doing so.
There is no accuracy in these pipettes, and they are The only time I would consider purchasing these would be if they are A cheap rubber cap broke when I tried to install it, and I wouldn't have been able to return it. In addition, they leak extensively Could be a good project for an elementary school, but not.
These aren't without their drawbacks, however. I can't say that these are particularly useful since the rubber bulb becomes frustrating after a while. As far as moving liquid between tubes is concerned, it works well, but I did not check its I dropped one of them from the counter to the floor and it shattered. It seems to be made of tempered glass, which is nice. Although the fragments weren't terribly sharp, they were still fairly large. One piece of food was left on the bottom of my sock because I neglected to sweep it up in my kitchen. For about an hour, I walked around without incident, and then I stupidly thought, "Wow, it feels as though there is something hard stuck to the bottom of my foot. ". I could not recall a greater moment of my life.
To begin with, I had no issues using these glass pipettes. My liquid cannot be touched by plastic and I needed them to measure and transfer it without putting any damage to it. There is no doubt that they are clearly marked, but they are also easy to use. Siphoning liquid into the pipette can be impossible if you don't get the rubber bulb onto the pipette at the top. With just a little difficulty, I was able to attach two, with the other two having to be attached after some You should be aware that these may not be an ideal choice if you have issues with dexterity. I am pleased with the purchase, because they worked, were well packaged, arrived in good condition, and served their purpose.
Those are handy if you do chemistry at home at all. They may seem like a luxury, but actually they can give you a lot of time back. In favor of The finest quality at a very reasonable price.
It's great to have these things! These enable you to fill dropper bottles with 5 and 10 mil droplets with ease. You'll have to allow a small amount of liquid to drip out after you draw it up, but if you arrange your space so that the bottles are right next to the liquid you are drawing up, you shouldn't have an issue. As well as the cleaning brushes that are included, I like them. I am very happy with my purchase.
The mushrooms I use for making ink with are made from these. I like it a lot. Also, I use it to handle essential oils when making soaps. If you need a large size for long tall bottles or shaggy mane mushrooms, this is perfect.
The tool is useful, but measuring specific quantities takes a bit of practice. It only works with liquids that are clear in color. It is impossible to tell how much liquid is in the inside of the glass due to thick and milky liquids coating it.
