One of the worse purchases I have ever made and I make LOTS of purchases! I rarely write reviews, but had to on this pipette. The readings are all over the place. All I want and expect it to do is measure PRECISELY 10ml of my aquarium water so that I can run tests for nitrate, alkalinity, magnesium, etc. Every time it gives me a different reading! One time it's 12 ml, another 11ml, another 13ml! I then tried dialing it to 8ml since it was consistently 2 ml off and even that fluctuates! It was supposed to help make testing my water parameters easy, but it's a waste of money! Will collect dust on my shelf!

No viene calibrada y no es precisa, no tiene un uso práctico en el laboratorio.

As the title says, this pippete does not come calibrated from the manufacturer. I tested it several times and it always collected/dispensed ~2ml more. I contacted customer service and all they said was sorry and that I can calibrate it myself. I understand that eventually I'd have to calibrate it, but it's beyond my understanding why isn't calibrated out of the box, specially when the manual clearly states that it is ready to be used.

So I’ve worked in a few labs and had to use Pipettes to draw samples. I found this from 1-10mm and thought it would streamline my nutrient process for gardening. It did, but it took me a little work to get there.When I first took it out of the package I filled a glass with tap water and began testing it. It dropped everywhere. I got upset and arranged an exchange. After I got off the phone I started playing with it and the accessories.First thing I did was take the cover off the end. It twisted off. Then there was a black housing for the piston. It turns a couple degrees then pulls straight off. There is a rubber plunger in there with silicone grease on it. I smeared the grease around better reassembled and viola! It worked!!Now I went to my garden and grabbed a graduated cylinder with 1ml markings. I ran through testing it at 10, 5, 3, and 2 ml (my common nutrient doses) and the meniscus sat right on the Correlating line.Not bad, I was happy and I cancelled my return. I packed it all up and put it away. Later on in the evening I was going to mix nutes and I thought it was a great opportunity to break it in. Well, wouldn’t you know it started dripping again. I switched over to my disposable pipettes and when I got done I started trouble shooting.I got the instructions out and read through them thoroughly. I payed particular attention to forward and reverse pipe tying instructions. I followed them step by step and drew 20-30 samples in a row with no drips.All in all I’d say it’s a great little device, accurate enough for my needs. I think it’s a little finicky, but that could also be operator failure. YMMV, but I think in the long run it’ll work just fine.
