ONiLAB 701010101014 1000ul High Precision Pipette, Single Channel, Manual Variable Volume Pipette

Works very well just don't release the thumb plunger to quickly or it'll shoot up into the neck. A slow release and it's spot on every time and exact measurement.

Hidden in the instructions, they tell you to “go to the first stop point” to draw liquid in. Initially, I was pushing the drawing mechanism all the way down and couldn’t see why it was taking up so much liquid. Then, I tried it as the instructions suggested (and pushed all the way down to push liquid OUT) and it was accurate to 1 mg. This is perfect for perfumery. Inexpensive and dependable. I can even clean the tips and reuse them. Well done, onilab! I’ll be back!

This aren't in the same league as the ones you find in professional labs that easily cost ten times as much, but they are fantastic for home/hobbyist use. I go through tons of single use pipettes that are inaccurate and wasteful, but with this, I just have to trash the tip and I'm back in business. It's so much easier to use too. And to anyone who is complaining about inaccuracy, I did not have that issue at all. I confirmed using distilled water on a milligram scale and found it to be very, very good in terms of accuracy and precision.

Definitely not callibtated. Make sure you callibrate it and you are good to go. These make you feel like a science god though.

Had it for about a month now, and the ejector already broke. It worked great when it worked but broke quickly
