Greylock Apothecary 1 mL Dropper Pipette Sets of 2, 6, 12 Calibrated Glass Pipettes - Ergonomic Bulb Design for Full Draws Every Time - 0.1 mL Increments for Precise Measurements - 12 Pack

Bought these to fit on my 4 oz essential oil bottles and sadly it does NOT fit on 4 oz NOW brand bottles as another reviewer indicated. It doesn't even get close to the mid point of the bottle to draw out oils once it gets lower, nor does it fit the lip to close the bottle. Not sure if I didn't receive the same product another reviewer got or if that was a false review, but I can confirm with certainty that it doesn't work on bottles of NOW essential oils. Photos attached to show how far it goes down the bottle and how it cannot reach the bottom.The pipettes themselves do appear to be nice with a strong bulb that doesn't leak back fluids you draw in. Just wish it fit my bottles and were longer to actually be useful. So the product itself is nice, but not useful for my intended purpose and why I purchased these pipettes.

These Droppers are the Perfect Size for Larger Essential Oil Bottles.Love them!!!! and the Squeeze Bulb at the top works Great!!!!

Working great for me. I should've gotten 18 instead of just the 6. I've been using them almost everyday since I received them. The numbers have not even begun to fade like some other pipettes I've used. The tops don't come off. I've heard that's a good and bad thing especially when it comes to cleaningcleaning. I haven't had any issues cleaning mine out. Going to invest in a few more. I wish this company had 5ml & 10ml sizes. That would be fantastic. Overall I'm pleased.Update: Ordered 8 more. Barnyard Shop, love u guys. Any word on the 5 & 10 ml's yet?

The syringes cannot be separated from the tops which makes cleaning almost impossible. Also it arrived with a shard of broken glass embedded in the inside of one of the tops. Since I'm using this to measure precise medicine for a baby, both these things make it impossible to use. Perhaps I should have realized it wouldn't separate but I can't understand who would use this device without being able to clean it. And the glass shard is, of course, unacceptable.

Absolutely perfect. I keep betta fish and measure all their tank additives in milliliters. The pipette I bought was great, but eventually the large bottles depleted past its ability to reach. I got some 2 oz bottles from the Glass Bottle Outlet here on Amazon, but the included lid pipettes are unmarked and only fill up about 1/4 of their length. These fit my bottles perfectly and allow me to accurately measure my micro and hospital tank dosages.As an added plus compared to the plastic bottles the additives come in, the new bottles are clear so I can see the “waterline” depth to insert the pipette. And now I have a separate pipette for each chemical, which is much better than rinsing and reusing the same one.All in all, a good purchase. Recommended.

these trully are the best glass dropper i have ever bought, work great. They do s-uck up more than 1ml so if you need it for 1.5ml-1.75ml these will work perfectly for that much too for that's about how much they s-uck up when pressing bulb fully. takes some getting use to on how hard to press for .5 and even 1ml amount but, no big deal. did notice given bulb design, dropper tends to swing when you depress the bulb to get liquid or oil out.. these did fit my amber bottles, my non see-thru black bottles from thoughtcloud and my others as well.- minor complaint; although pic does show it not doing so, therefore my fault for not noticing, is that these don't reach down far enough and leave about 1/8th+ of the oil in all the 2oz various bottles unreachable, therefore a long pipette will still be needed..-major complaint; whyyyy are these awesome droppers not available for 1oz bottles! was already going to talk to my hubby into figuring out how to shorten these at the part where it goes into bulb for me but, these don't seem to actually separate from the bulb (tried, the pipette wasn't budging) so can't do that...so please seller/maker consider offereing these same styles for smaller bottles.

These are very well made precision instruments. I use them to draw water from my aquariums to put into API water testing test tubes which have a mark at the 5 ml mark. The pipettes make it easy to get the exact amount of water without going over the mark. They are very well made, each pipette exactly alike and each wrapped with foam for protection.

So far so good. I am using these droppers to administer medication. It is great for precision dosing (if you require a 0.5-1 mL dose). All six came intact. I have no reason to use more than one at a time, so all I can say is the one I am using now works well, and I have 5 back ups if/when it breaks!
