2-Pack 10ml Glass Graduated Dropper Pipettes for Lab Use

Amazon CustomerAmazon Customer: This is exactly what I wanted, meets my need perfectly for drawing water from my fish aquarium so that I can fill test tubes precisely to 5ML to test the water. This saves me so much time. It comes with 2 pipettes, my only complaint was the second one when I put the rubber part on was so tight it actually tore putting it on, but whatever I only needed 1. Chemistry class finally gave me a real world use case knowing this existed.

C M: I needed a measuring device to get nutrients out of a bottle and into my AeroGarden. This works perfectly. Before pouring the nutrients from the bottle into the cap and then into the AeroGarden was a nightmare! A mess everywhere! Dripping down the bottle, overflowing the cap, missing the garden opening! This has definitely helped me tremendously from getting frustrated!

Justin: The measurements were relatively accurate. Clean easily as long as you dry them near a fan to get the water out of the inside. It is pretty tough to pipette a full 10ml at once. I usually would only get about 8ml at max. If I squeezed any harder to compress the bulb more my accuracy would decrease due to my hand shaking. The photo shows a cleaning brush but I didn’t receive one which is why I’m giving it 4 stars.

Jonathan Swearingen: I've had these for a while now and finally decided to write a review. They haven't broken nor chipped, they seem solid. They might chip if they fall off a counter but honestly I wouldn't be surprised if they didn't even crack from a casual drop like that although I don't think I've dropped them.

crazyjake: I bought these to use for acid additions to my brewing and hydroponic water for pH adjustments. The items were packaged well and nothing was broken upon arrival. Package includes two glass droppers with rubber squeeze bulbs, two glass stir rods, and a cleaning brush.

My only gripe about these is that they are not exactly like the items pictures, which show the number for each full mL measurement. While the ones I received have a wide line to denote each full mL, only the even numbers are shown on the glass droppers. Disappointing but not a deal breaker.
