Golgi apparatus

There are two reasons for this: A) the compu-stage is a very delicate piece of equipment movable in all directions (x, y, z and two tilt angles) and we don’t want it to get damaged; B) all high-resolution EMs run a high vacuum (as the electron beam would get dispersed in air) and inserting the specimen rod incorrectly poses the danger of allowing air into the column, which then means having to pump the microscope for quite a long time before it can be used again. To allow the specimen to be inserted, the sample rod needs to go through an airlock, which is the pumping noise that can be heard when introducing the sample.
