    Why does a science forum not have pictures of mice and rats?

The internal components are easily knocked out of calibration if you drop the pipetter. My opinion is that storing upright on a hanger ensures that the pipetter isn't dropped (even a small distance) while horizontal. In addition, it would be natural to store the pipetter horizontally in a drawer, where it would be subjected to even more jostling. The recommendation to hang the pipetter on a carousel discourages this practice.

I don't think that there is a specific reason, I've never seen a publication with this topic.
A reason to do so maybe that when someone has got fluid in the pipet it will drip out and not contaminate the plunger.

It saves space on the desk/bench that is anyway strewn with stuff and equipment.

That is....if she posts at all.

Maybe in your lab, Dr. H! :P My bench is sparkling clean at the end of every day...

:rolleyes:
So, Dr H, do you interested in taking me in the future? I feels like I do share some similarity with them. :P :D
will try to post a picture of my recent bench soon...

In some manuals it is mentioned pipettes are stored upright to prevent liquid from getting into the pipette (and corroding).

This is what they told me too when I got an introduction on "how to work in the lab".
