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

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...

I shall stick to collecting from marine environments, like the warm and sunny beach where
South Pacific was filmed. Your comment, Lorez, well taken, thanks.

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, ...

Re: Microscope storage

Some place it right on top of the specimen, others over the top of the objective, and others in the head assem...

Please forgive me for that post. I misread someones question about which

How did you organize? I have the 3 basic scopes, with 8' of desk space. Other than by
weight or price I can't find any reasons for which one goes where.

Re: Doing Diatoms

"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."

What designates a 'research lab centrifuge'?

Cool. I'm awaiting some lab stuff to try all this, and have yet to order the cleaning
chemicals. The link you gave me for the HP is for 8oz, would you suggest a larger
quantity? 16oz for $12 ?

Yup, graphite fingerboard, carbonfiber neck, and ballbearing tone ring suspension.
One of the first made, and handed to me by Tom at Wintergrass.

Wahoo, quickly send me details. Dale Oops, sorry, Apo, I thought that link was from Lopez, who has friends with parts with attractive prices! Honestly, I can't think of another objective I could use. My spread is 4-10-20-40-60X. I dont use oil, so a 100X is out. BTW, the 15X eyepieces work very well...
