Review on Scientific Microchemical Disposable Pipette Pipettor by Dang Esq

Received the pipette yesterday. I took it to work today to try. It's relatively cheap, so my expectations were moderate. Although it was a busy day, I finally got a chance to try it out for a few minutes. To evaluate the instrument, I used the analytical balance in our laboratory. Tenths of milligrams can be resolved when reading to 4 decimal places. I randomly selected 4 samples. I set the pipette to 5 mL and drew 5 mL of Type I deionized water and checked the mass of the collected sample with a balance. Obviously I didn't do a proper calibration check, I only had a few minutes to see what it would do right out of the box. The average weight of 4 samples was 5.0128 grams. The lab was within 3 tenths of 20C all day. As a result, the dropper gave me a normal 5.0mL for all 4 doses. I am with what I am saw today, completely satisfied and look forward to testing the device in the future. Nice? Absolutely worth buying. We'll see how it holds up over time.
