Great video and observation. Thanks for sharing.
How long does this process of budding and reproduction takes till the new creature breaks free?

Re: WTB: Zeiss Universal, Photomicroscope II or III stand
Hi,
also note that the Zeiss Stand WL focus block is the same as used on Phomi and Universal.
I used a Phomi focus block to fit it on one of my Zeiss Standard WL.

I can confirm this statement.It's held on with like 6 bolts, there are no alignment issues.

Re: Need help with a stuck part on a Zeiss PM3 tube head
Hi Scarodactyl, This is heresy, but I have once replaced it with a normal set screw like it should have had in the first place. Wonder why you replaced the wonderfull, over engineered, spring loaded fixation mechanism? :D After re-lubricating it will do again a nice job for the next coming 20 years....

Re: Need help with a stuck part on a Zeiss PM3 tube head
Hi Tim,
I have used the Zeiss GF 30 gear grease. But a soft to medium viscous gear gease should generally do the job I guess.
In the German Forum there is also a member who sells a comparable grease for quite low costs...but maybe would not work due to shipping costs to USA in your case.

Hello Tlansing, thrust me, from my own experience do not try to remove the threaded brass sleeve...it is not required and has NO benefit.

Re: Need help with a stuck part on a Zeiss PM3 tube head
These pins need to be completely dismantled. Use petrolether or xylene to remove the old, hardened grease. Relubricate and re-assembly. Here you find the details of the pin mechanism. The principle is all the same on the Zeiss standards (PM): https://www.mikroskopie-forum.de/index.php?topic=4004.msg...

Hi Javier,
a nice video, well done. The Rotifier obviously makes a good object to demonstrate the different effects.
Just the simple bright field illumination is missing![Smile :-)](./images/smilies/icon_e_smile.gif)
