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

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.

I've been using these to dose cattle pour-on Ivermectin on my chickens and turkeys. The fluid ruins syringes within a few uses, but these work fine if you don't drop them. I wish they were less breakable, but plastic would degrade faster. Overall, these are far better than any alternative I've found, and a good buy.

These are calibrated 1 ml droppers, though the 1 ml mark is about 1/2 way up the glass. With such a bulbous bulb, it is possible to fill the dropper to the top, but there are no calibration marks beyond 1 ml.

These are great for tinctures and extracts. They make my gifts look like professional products, and people love how easy it is to dose with the graduated pipette.

These do not fit a 3 inch bottle. I had to push the stem into the plunger a bit to get it to fit. Otherwise a good buy.

Definitely no low squeeze...very accurate fill every time. Great tops for my 2 ml oil bottles.

very nice quality and looks just like the photo.

Worked perfectly for my art project.
