Re: Alboran Sea Diatoms
I tried to make a test permanent side from this sample. I wanted to make a test slide because diatoms react different ways depending on their shape and side. I was trying to see if they would shift during the mounting process. I figured the most likely ones which would shift are the large ones like ...

Re: Buying expired slides - hit or miss
This made me look at my slides.

They do have catalog and lot numbers and date manufactured, but none with expiration da...

For a simple fix, you could seal the edges with varnish or fingernail polish. That way, you wouldn't need the tape.

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 ...

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...

It does look 'crusty' but, you are getting a Standard 18 with 5 objective turret, a trinocular head, phase condenser and lighting with power source. Something a person could work with.

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.
