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.

Maybe in your lab, Dr. H!

So, Dr H, do you interested in taking me in the future? I feels like I do share some similarity with them.
will try to post a picture of my recent bench soon...
Expecting the world to treat you fairly because you are a good person is like expecting the lion not to attack you because you are a vegetarian.

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".
