Re: Zeiss Photomicroscope DIC Inko questions.

What is required beside your #2 DIC slide and DIC condenser is the polarizer and analyzer to obtain cross polars first. The #2 DIC slide has the analyzer and you would need a polarizer under the condenser. The equipment should work even with the IIIRS fluoro unit as long as you're not going through ...

Fantastic diversity.
From which depth (in the mud, and below the water) was the sand collected ?
It is great that you do not boil in acid any more.
I still acid treat, but just let the sample set in it and not boiled. See the edit above.

Samples off of rocks two feet under maybe too deep. Look for rocks near the surface which are slimy to the touch. Once you scrub the rocks, let the water settle and put a drop of the concentrate under a microscope to see if there are any diatoms. Drano's main ingredients are basis (sodium hypochlora...

Re: So how do you prep a tuna slide?

I don't believe plastic can get into the flesh of fish or other animals and show up as filaments. They would need to be digested at a molecular level and you would never see strands of plastic in the flesh. Most likely it may have been in the stomach or other contaminants while processing.

You can get good darkfield with just side lighting. One in each direction and proper positioning will remove some glare you might get.
