KINGLAKE Plastic Transfer Pipettes 3ML,Essential Oils Pipettes,Graduated,Pack of 100, Makeup Tool

A key thing to remember when using transfer pipettes is that they are not meant to be extremely accurate. They get you to a ballpark amount. One should use a graduated cylinder or a calibrated pipette to do closer measurements. Accuracy wasn't the reason for my purchase. We used these in our labs while I was a student and we used them when I taught chemistry. It would be absolutely unfair to think you could use one of these and get an exact 2 mL (or whatever measurement). The key for transfer pipettes is to make sure that when you squeeze the bulb that the bulb then opens to fill the pipette with liquid which can then be transferred. That is their purpose. Transferring a mL or three to another container. They are meant to be disposable so you do not mix solvents. If you are planning to reuse them, they can be labeled with makers or an adhesive label. With that in mind, I am writing this review. These pipettes are exactly what I expected. The opening where liquid is picked up is about 2mm. For some fine measurements this would be too big. For transferring liquids to vials from a larger bottle these will work great. I use them for transferring essential oils so I don't have to cart my essential oil bottles upstairs every time I refill the diffuser. Much easier than trying to pour the expensive oils. I can recommend these fully.

I purchased these because I'm beginning to dabble with creating homemade cleaning, skin, and hair care products and I needed a way to extract essential oils and carrier oils in an exact way for recipe writing. EOs and some carrier oils are expensive and using pipettes help me from cross-contaminating the oils as well as use more precision than just "eye-balling" the amount of oil. These pipettes are great and the price for the number you get is very competitive. I like them very much. I'm certain there are other uses for them but as I mentioned, I only use them for oils.

As advertised, consistent markings. Can’t imagine I’ll need more for a while. If I do, I’ll be sure to purchase this pack once again.

We used these for a craft to make T shirts with Sharpies and rubbing alcohol and they worked great. They are better than the medicine droppers we used last year because they don't let as much liquid out as quickly and so the craft was better controlled without the T shirts getting too wet. With the great price, each kid could have one to themselves so we didn't have to share.

Bought these to use to transfer essential oils to smaller bottles for samples and giveaways. They were easy to use and dispose of for each single use. They sucked up the liquid easily with one squeeze and it didn't drip out until you let it go when needed. Often these things drip all over when moving from from one container to another but I didn't have any problems with these doing that. I like that they are nice and light as well . I would definitely order these again if I needed.

Wow! What a great purchase! My refractometer came with only one pipette for testing wort (beer). I found this bundle of 100 at a great price, and now, rather than reuse the same one over and over, I just recycle that one, then grab a fresh one when I need to test. This pack should last me a long time! Recommended!

Used these for kids' rockets and they were great. Pay attention to the size--these are fairly small.

For viscous liquids, the opening can be easily trimmed back, which makes the opening bigger, to allow a quicker fill. I use these mostly for resin art and molds for resin, which allows more control for resin applications. Inexpensive and there are a lot of them. So the supply lasts quite a long while.
