I could not read it because the explanation was only in German. I do not know whether it is a problem of making the silicon part of the pipette insertion port, but it hangs up even when I want to suck it up and keep it. For the lever under the wheel, it flows out rather than dropping a minute amount. There was explanation that fine adjustment to the micro range can be done, but it was not true. It was disappointing though it was prepared to some extent because the price was affordable. I hope if you can also write the producer country if possible.
Dispensing operation using a Pasteur pipette with a diameter of about 7 mm

Like a safety pipettor, it is a tool for safely and conveniently operating a pipette, but it can be operated with one hand, it is a very excellent product in workability because it can perform a sucking / discharging operation like a syringe. Especially useful when dispensing continuously. Somewhat satisfied reason: · Sometimes internal grease up is necessary (not maintenance free) · Spring of the lower part (under the wheel, pushing the lever, opening the valve under atmospheric pressure) is weak or sealing it once it is opened There was a problem that there was a problem that the liquid could not be retained after inhaling (gradually leaking liquid). The latter is not a problem to be troublesome, as we solved the problem by simply extending the spring a little bit and strengthening the force to hold the hemispherical rubber part (sealing the open hole), but if possible improve I would like to ask you.
