Interesting Attachment......ID???

Anyone know the intended purpose of this attached mounting bracket? I think it is for a POL microscope. At first thought, such a DIY attachment would seem to be fairly easy to fabricate and offer some great potential for a non POL unit when using lower power objectives with longer working distance. ...

Re: A few starch grains from a potato

Thanks for the kind words mrsonchus. I was actually disapointed with the image but I find them rather attractive for starch grains. :) Producing these is quite simple. Just slice a potato, brush the "juice" from the fresh cut surface onto a slide with a drop of water and you have them. Under normal ...

Re: Does anyone tried metal washer and flat rubber o-ring as spacer?

These type slides are an alternative to a well slide Bob, not intended for permanent mounts. The idea of using a cover slip with them could slow water evaporation but normally they're used without one. With some protists moving constantly in and out of focus a "poor image" becomes somewhat a moot po...

Re: Does anyone tried metal washer and flat rubber o-ring as spacer?

If you intend to make well slides they would work. However I would use nylon washers, (available at the big box), and forgo the metal and o-rings. The nylon work very well. If you are wanting spacers, you could use broken cover slips, a drop of super glue spaced to roughly match to the corners of yo...

Thanks for the quick response MrSonchus. My interest has evolved toward botany and I think I would like to pursue that area.

Info needed on AO 820 "tome"

Are there blade holders available for the AO 820 which allow the use of regular razor blades? If so where might I locate one and what might I expect to pay? I presume if available it would clamp into the standard blade holder. Will also appreciate any alternate info or suggestions.

Thanks for that Jimur, they are cheap enough to have a try with and if it doesn't work I can keep my coffee warm 🙂
With the proper size ceramic tile it could multi-task by drying a few slides and keep your coffee warm at the same time. :)

Re: Hot plate?

Although I have a slide warmer and have used it preparing slides in crystal growth I generally get better results with longer drying times. I would think a coffee warmer with a small ceramic tile sitting atop it would work well.
