Weewooday Glass Droppers Pipettes Graduated Lab Dropper Glass Liquid Pipette with Big Rubber Hats 20 cm Stir Rod Washing Brush Transfer for Liquid Essential Oil(16 Pieces,Blue,10 ml)

These are great. they are a little bigger than I needed, but they are sturdy and have a graduated scale along the side so you know how much you are applying. I love that they are glass, and won't add unnecessary plastic to the environment when I'm dead and gone. They came with two brushes for easy cleaning. A solid, useful product.

Love them. Good quality. Nice.

I got these to use in my big bottles of Fragrance oils. They work perfectly. Grat suction, it measures perfect too. They reach to the very bottom of the tall bottles when they are almost empty which is what I needed these for. The glass is a nice thick sturdy glass. The bulbs seem to be made from a good rubber material s I think they will last awhile. My only concern was they arrived in a shipping bag that contained a thin box with all the components in it. This box was crushed upon arrival. I was afraid the glass parts would be broke but they were wrapped in a bubble wrap which I guess saved them or I was just lucky. Otherwise, the product itself is really great quality.

Work well, strong and robust. The graduations do not come off with mineral spirits or acetone. Best of all, the bulbs are actually large enough to suck up 10 mL of fluid. That said, the packaging is terrible and I am shocked that nothing was broken.

Perfect glass dropper I only needed one but good to have spares and the cleaning brushes that came with them I use for testing 5ml of fish tank water.

If you need to be precise with the ml (or ounces) dosing for liquids - then these will come in HANDY! I have used these to precisely measure out 12ml of liquid (vs. the 20+ that would accidentally come out (and spill due to the backflow)).The glass stirrers are useful for stirring liquid while being easy to keep clean (rather it is oily or non-oily). The brushes are nice, though they don't go all the way to the tip (which can be tricky to clean regardless)).The size of the droppers did take me back a bit. I wasn't sure what to expect for a dropper sized to extract up to 10ml of liquid at a time - but these are definitely not small and petite (despite how they appear in the picture).

Perfect for my need to add distilled water to a flooded car battery. Actually this one is on my standby generator, but same thing.

These work so well, I am a little sad I didn't find them sooner! The company even included two cleaning brushes that fit these perfectly within the package. Would definitely purchase again.
