شكرا good

Worked as expected and priced well compared to a lot of the lab equipment you'll find online. No complaints.

Nice and accurate. I use this for my reef tank. Far better than 10 cent syringes. As others have noted- don’t push all the way down. Slowly apply pressure until you feel a soft “stop”, then slowly release- never let it spring back. The second full stop is unmeasured and just for pushing any remnants out. One thing that would have been nice is if they included multiple tips. Can’t really use just one for everything.

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.

I purchased 3 of these for testing aquarium water more precisely than the disposable 5ml or 10ml syringes supplied in most aquarium test kits. 2-10ml version They are not even close to being accurate, as measured with certified graduated cylinders. Not only are they not accurate, none of the 3 are off by the same amount. Depending on the scale volume set, they are off by .2 to 1.2ml Complete garbage. I get far more accurate results from the disposable syringes, as sad as that reality is. These are glorified eye droppers, no more. Stay far away and realize why an accurate pipette costs hundreds of dollars, and hope that your local lab, doctors office or testing facility is not using this garbage.
