Re: Diatom 640X Oblique Illumination

Thank you mrsonchus
These are quite a bit more informative than the previous "No Entry" signs ;) Very nice to see the technique so well used on botanical samples, rather than the usual pond life studies.

Re: Programmed nuclear death in Paramecium

Can you give me any idea (order of magnitude: minutes, hours, days) of how long it takes from completion of conjugation to completion of the programmed nuclear death process - i.e. complete resorption of the fragments of the old MAC? I wasn't sure so had to check the literature and it appears the p...

Apparently eosin aqueous solutions are very prone to mould growth, so I suspect bacterial growth could also be an issue.

Re: WTB Slide Storage Cabinet

A worthy project well worth the invested sum. I still don't own a 3D printer but seeing what you guys are doing with them has piqued my interest. I assume you have to create a program to print something like this? I'm not very computer savvy so that's probably my main hesitation. Are those all your...

Kirby Thanks for the kind words. For printing I used a standard Creality Ender 3 printer which is relatively small and cheap but still has a good build volume. This project doesn't exactly stretch the printer to its limits on size but it is getting close. I used a PLA filament that I buy for $35.00 ...
