All our objective bottles actually store them this way.  The lens screws into the lid of the bottle and points down.

Subject: Oil in a 10x objective

Can anyone come up with a plausible explanation as to how oil got
into the 10x objective on our LSM510 with an upright stand? Yesterday
someone complained about poor imaging through the objective, and I
discovered that there was a bubble of oil trapped between internal
elements. I'm at a loss as to how someone got oil inside this low
mag, non-immersion lens. Any ideas?
