Review on Adjustable Single Channel Pipettor with Scientific Precision by Tim Wadman

The pipettes I have received are very, very good, the quality is first class and second to none. Unfortunately, they sent me the wrong way, and even with the replacement model, they sent me the wrong way. The spares they gave me are excellent, they have no defects but as I said when I open the box of one of the spares I did not open the other, the instructions were the same as the first one saying that They have to pull the handle out with a tool and they don't say anything about how to unscrew what they did they sent me pictures a pdf file with pictures to show me how to do what i would like to change my rating from one star to five stars, it is a very reputable company and we will do our best to satisfy our customers, thanks to FourE's for your generous response. I would buy lab equipment from you and anything else I need you sell whenever I need it, thanks again Sean Captain
