Merry Christmas, jimur

Thank you very much BramHuntingNematodes. The thread speaks volumes of a portion of today's society.

Merry Christmas everyone.

Enlarged, it appears more chemical to me.

My guess is Asellus aquaticus (common water louse) The 2nd photo looks as though it's curled back over itself to me.

Thanks all. I knew one of you guys would know.

Looks to me like it's meant for a low profile knob, to engage the gear rack.

Seems you're correct. Thanks PeteM.

Here is a Zeiss point count mechanical stage: On a Pol scope:

Very clear. Thanks Charles.

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. ...

I would say yes to Arcella

Thanks 75RR and thanx for the link also, I'll hang on to that one.

Sorry for the lack of detail but is this a form of Arcellinida?

where do I get the handbook?

Google the title Don and screen the results for "free" and or "pdf". You'll need the Adobe reader app which is a free dnld also.

there are plenty of books on microscopy, new and old written in English, and a lot can be downloaded for free..

Can you give me some references?

Handbook of Basic Microtechnique (free pdf download) There are scores of others.

Yep, it's kinda nice Rapidray. Welcome to the dark side.

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 ...

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...

Poor man's pol

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...

mrsonchus » Fri Sep 11, 2020 2:54 pm You'd be surprised how good an ordinary razorblade may perform when well-mounted.. Here's a post of mine from way-back Quite impressive Mr Sonchus .Perhaps I should just find a good source for cello tape and save my pennies until I can pay $200 for a low profile...

probably chatter quicker than comfortable

Interesting Bob. I would not have thought there would be enough blade exsposed or cycles per minute to create chatter.

Thanks for the quick response MrSonchus. My interest has evolved toward botany and I think I would like to pursue that area. I just stumbled across a blade holder shown in the 820 ref manual which shows a Model 966 razor blade holder which mounts into the standard knife holder. Screenshot 966.png-00...

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.

You might want to get a group together and share the cost. https://www.tedpella.com/section_html/p ... clear_wall

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.

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.

Not exactly sure what you're looking for but............... You might find this link interesting. It's a DIY which I've used occasionally and pretty simple to make but can be difficlt to clean. There are others including a couple made with salvaged binocular prisms which is a little more complicated...

If you haven't done so as yet follow this link to http://www.microscopy-uk.org.uk A very informative UK site. I understand you don't care to mix your own now but you may change your mind in the future. Once on the site search WALTER DIONI He has an excellent series on very worthy DIY medium for diff...
