Single Channel Pipettors Adjustable Volume Micro Pipettes, 0.1-2.5μl (7010101001)

Unfortunately I don't have a scale that reads to three decimal places, so I can't quantify the repeatability by mass. That said, there appeared to be repeatability in drop size at different settings in the 0.5 to 10 uL range. I bought it to spot TLC plates, and it certainly works well for that.

I needed something to accurately add smaller volumes to my aquarium. I didn’t get this calibrated but it’s hopefully more accurate than the dropper pipe type I was using for my 5 gal tank

I have an aquarium. I test the water. It used to be a pain to get 10ml of water in the tube to test. Dip the tube in, look at the level, dip again for more water or tip a bit out. The tube, and hand, was wet. This thing is wonderful. Dip it in the water, press and release the button, put the tip in the tube, press the button again. 10ml in the tube. Can I do without this, yes. Does it make my life wonderful with butterflies coming out my but, no. Does this make a not very enjoyable thing I have to do a little better, yes. A lot of "laboratory" things can be used outside the laboratory and make lots of things easier. I have a laboratory thing designed to shake bottles that I use to shake my water testing tubes. It has a window showing how much it will move. Turn the button top to change this. These come in all sorts of different sizes. The one I have does up to 20ml. You can set it by tenths of a ml. You can also make tiny adjustments do if you set it to 10 and it is doing 10.1 you can adjust so that it is doing 10. I find that I turn the button on top when using it, so I have to check that the window still says 10 occasionally. They could, easy for me to say, do something different to make it harder to change the amount by accident.

Very helpful! The number on the puppets does not match grade A graduated cylinder. If that is a problem adjust the number to match your standard and use the color codes instead of the numbers.

Making my own coca cola clone per Lab Coatz youtube instructions. This is the same model he uses. Very simple to use.

Excellent sales service, the product meets all requirements. Thank you

I totally cloned some dinosaur DNA successfully and smuggled it in a shaving cream can. A++

It was delivered broken. Everything booked to be working order until I went to use it and it literally doesn’t pull up any liquid.

No tiene ni dos meses que la compre y ya dejó de funcionar. Solo la use 5 veces para medir un volumen de agua y dejo de funcionar ....

شكرا good

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.
