Re: Doing Diatoms
ZZ, glad you are not in a hurry, as I have to pick one of 3 machines to transfer a ton of vhs tapes. Not wanting to waste the Pensacola sand I have been trying to filter other stuff, with messy results. Now I am at Ocean Shores, and will bring home a bucket of real sand. With my lab packed I am quit...

Thank you Bill, I missed that option. I intend to cut them into circles to place

Re: Doing Diatoms
Two questions: 1. I have 2 vcrs headed for the dump, but I could salvage the drums for any slide ringer wannabe's. 2. Fan, how did you ship the ziplock to Rod? I'm still looking for the cheapest way to ship sand. 2.1 For the first gross filtration I'm looking at putting a round mesh screen into a Bu...

Re: Finding Diatoms
It is the Lumahai Beach, home to one of the worlds richest olivine sand deposits, and the most dangerous beach. Lumahai means bad water. Any aerial view will show the lava spike at the West end. I found a Hawaiian lifeguard forum, and they advised using a scoop taped to a long stick, so as to not cl...

Re: Finding Diatoms
I got the #210 and #500, and I assume the # number is the same as microns. The small squares work well over petri dishes, but for larger samples having the mesh in a frame seems useable. The sieve set Lorez referenced was way too expensive, but very attractive. I also need to attach a scoop/sieve to...

Permanent analyzer placement in Nikon Eclipse
Not wanting to frequently remove the head on my E600 to place an analyzer filter for polarization lighting, can I leave it there? I know it should be oriented front to back, but what affect would it have on BF, DF, and phase ? I leave a high quality polarizer on my dslr with no detrimental effects, ...

"I think the sand/mineral particles are heavier (more dense) than diatoms and should sink to the very bottom of centrifuge tubes. Diatoms layer should stay above sands, if you spin fast enough. At least, that would happen in research lab centrifuges."
