Re: Starting with identifying a decent microscope

Kurt, Yes. Q-Tips and cotton balls from the grocery store or pharmacy, but gently. Pressure can drive any hardened debris into the soft optical glass of the lens and cause a scratch. I really dislike lens tissue. People tend to just stick it on their finger and rub it flat on the objective lens, usu...

Re: Starting with identifying a decent microscope

Amoeba, I did also come across this: http://www.quekett.org/ A fair bit of information it seems, but you have to pay to join in order to access much of the site. Since you are in the UK, and new to this (and actually even if you were not) Queckett is one of the best resources available. LOTs of loca...

Re: Viewing Red Blood Cells

.. Immersion Oil can be applied directly to a dry specimen of Blood, with no coverslip. Clinical labs do it all the time for CBC's and body fluid smears. No one coverslips grams stains or the like, either. A thin layer first to substitute for the coverslip, then a larger drop when using the oil imm...

Hi Moose,

The adapter is in good shape and I do have a spare NFK 2.5x projection eyepiece. $225 for both, including shipping.

Re: Wanted: OM Photomicro Adapter L

Hi Moose,

I have a Photomicro Adapter L I'd part with, and I think I have a spare NFK 2.5x projection eyepiece, too. Let me check later this morning to be sure the adapter is in good shape.

Re: Smear mounts and immersion oil

Even, During my 40 years in clinical labs, I've looked at many, many thousands of hematology and gram stain smears with oil immersion and no cover slip. In fact, I've never seen anyone use a cover slip unless it is a permanently mounted slide. Just make sure they're dry first! While using a cover sl...

Re: How do you keep track of image metadata?

Discipline. No matter what method you use, it will require discipline to succeed. :shock: Treat your microscopy as a scientific examination, and the photography as part of a method of recording that examination. The other part, just as necessary, is consistently recording metadata. The key is consis...

Re: MAYBE THIS SHOULD BE IN BEGINNERS CORNER but....

CE, We never had NC objectives in the hematology labs I've worked in, and never used cover slips on non-permanent slides. We always spread a drop of immersion oil across the dried blood smear for low magnification to eliminate the diffraction caused by the dried cells. If, after we added another dro...

That gives you effectively an infinite number of choices :shock: . Experiment! You can spend your entir...

Re: Advice about possible Bh2 purchase please

Ask the merchant if he'll swap out the infinity objectives for a set of DPlans. Pick up the right NFK projection lens for the trinoc and you're on your way. If he won't, and the price is nice enough, buy it, sell the infinity lenses for whatever you can get, and replace them with DPlans (or Splans i...

Re: easyzzom test

VERY nice! :D The annotations work very well, too.
It looks I need to do a bit of home work to see if this is better than Zoomify. I'm mostly interested in a stand alone solution.

Any comments Oliver?

Thanks everyone! If you can get to them when they're young enough, you can twist them pretty much any way you like. 8-) I've often thought the instrument manufacturers should do something like this, but on a much larger scale.

On October 29th, I had my microscopes set up at a Science Fair Expo at the Riverside (CA) County Office of Education. Lots of displays and workshops for the kids wanting to do science fair projects.

Re: investigated 2 places for microbes

Very nasty indeed.

The CSF finding was a big surprise, but not as much as the patient's survival. If I recall correctly, that was the very first survivor. So just like finding a massive number of malignant cells in CSF, pleural or peritoneal fluid, you're looking at a dead man walking.

Different amoeba, different target, different symptoms. Only just ugly, one almost always fatal. Entamoeba histolytica, GI symptoms usually, ugly diarrhea and sometimes organ (liver, etc,) abscesses.
