Blood films are heat-fixed the same way as bacteriological smears: let the slide dry and poor it 3-4 times trough a not too hot flame, preferably a flame from...
How does one find a microscopy club? How long do you hold the slide in the flame on each pass? Yours, Dora Smith Austin, TX tiggernut24@... ... From:...
* Google? * Nothing wrong with some trial and error... Just pass it slowly trough the flame a few times. Every pass should take some 2-3 seconds only. ... ...
Hi all, Yesterday, in bottom sludge from a spring I found a diatom that I have never seen before. Would the diatomaniacs take a look and see if they can help...
My guess is a side view of a gomphonema species. Yours, Dora Smith Austin, TX tiggernut24@... ... From: Dan To: microscopehobby@yahoogroups.com Sent:...
Hi Dora, Gomphonema has some beautiful shapes, so I think that is a good guess. I cannot find any pictures on the net to back that up. I think the diatom is...
Key is that the ends aren't the same size. Yours, Dora Smith Austin, TX tiggernut24@... ... From: Dan To: microscopehobby@yahoogroups.com Sent: Monday,...
Dan, A lovely specimen! You have Entomoneis ornata (Bailey) Reimer. This genus used to be called Amphiprora, and you may find it under that name. The...
Hi Group: I am new to this hobby, and have some "dumb" questions.. 1.. Where do you find Diatoms.? 2.. How do you prepare a slide for viewing Diatoms.? 3.....
Diatoms can be found on rocks and in the mud near and in any body of water, atleast as deep as sunlight can penetrate. They also like to grow in home...
I just finished making two incinerated slides of diatoms from Bartlett Reservoir, Arizona. When the cover slips were dry, I noted that there was an unusually...
Hi Nessie These aren't dumb questions as they remain relevant no matter how experienced you are and the best researchers are still seeking answers to elements...
  Hi Richard, relateing fluxes in ceramics heat cycles to high salt solutions with diatoms reminds me of colligative properties of aqueous solutions in...
Charlie, Thanks for your comments! I'm sure you are correct about marine diatoms, and I would not try incineration with these without several washes in DW. ...
Yvan, Back from a trip I'm catching up with my emails. First, thanks for this excellent summary on the use of M-G-G. Now a question: some old timers, very,...
I usually study diatoms with PC, but sometimes the resolution is not the best, and oblique BF works better. I've placed two photos in my album (Dick's...
  Hi Dick, beyond my expectations, patiently...Leszek, Bill Dailey, Michael-TOG, Yvan Linderkins(?sp?)...and you...have drawn me to appreciate directly/and...
I took some "scunge" from the bottom of a pool and there is "life" in the sample. How do I get rid of the garbage (it blocks out the good stuff) , so I can...
I came across a paper that stated that oblique lighting can effectively double the resolution of an objective. This paper used curved stops in the light path....
I wouldn't say I study diatoms, but I have found this too. Â I spent some time yesterday looking at a Kemp 8 form test slide and was able to resolve the...
The ap I mentioned is the small one - amphipleura pellucida. I used a 100x na 1.3 objective and a 1.25na condenser, both oiled. I also used a green filter. May...
Thanks for the hints. I'm using an M20 with 1.3 / 1.3 condenser / objective. I didn't try green filtering it... because I forgot. Â The oblique stop is an...
Hi Mark, a proper Wild lens should be able to show Frustulia (the second from the end) in dots in brightfield, with a dry condenser. If that one doesn't show,...
