Biohit M Series Pipet Pipette Pipettor M20 M100 M200 M1000 M5000

Used by me in a wine laboratory service I offered as a consultant. Serviced in 2017 and used lightly for two years. In storage ever since. Excellent condition. The M1000 is missing the filter in the tip. The M20 and M100 are missing a cosmetic trim piece in the hook part of the pipette, where you would hang it up on a rack (see photo).
