Hello All! I've been working at finding an effective slowing agent that will slow the critters and not kill them. My initial material was a 2.5% Methyl...
Mike, You might try the chewable Fiber Source tablets http://www.fiberchoice.com/ made of 100% guar products the inulin and gum make a pretty stiff fluid. It...
Hi Mike, I have scanned and uploaded a very detailed study by Gustav Delly on this very subject - you might find it interesting (being a lazy so and so I have...
Hello Ron, Thanks for the information; as usual Delly has done a beautiful job of detailing what/how things work. I know the 10% methyl cellulose is supposedly...
Hello Gordon, Thanks for the suggestion, but being somewhat of a purist, I'll hold off until I find a source for the pure (99.9) material. If I get too...
Mike, You quest for purity may be part of the problem giving you a very fast of change in viscosity over a narrow range of concentration, temperature and/or...
Hello Gordon, Actually the reverse is true - by starting with pure methyl cellulose (or any other chemical,) one knows exactly what the concentrations are, not...
Mike, Colloidal chemistry is difficult subject. Pure substances have more predicable behavior. That includes getting the concentration, temperature, pH an ions...
Gordon, Not sure what(or which) your point is! Many areas are difficult subjects - colloids isn't really one of them, if it were germane to the discussion. My...
Hi Mike, I must say, that I agree with your position 100%. It is obvious to me, that you know what you are talking about, and understand the subject matter...
Mike, I agree 100% that pure chemicals have more predicable results. But when you mix up a media to keep animals alive and to slow them down you don't have...
Gordon, et al., I agree that pure chemicals are best, but also it depends what you need to do. If the object is just to slow down the critters anything that...
Hi All, OK, is it me, or is the picking on ebay getting worse by the day? I did find another Dynazoom, with no bids, starting at 99 cents, but the guy wanted...
Stan, 'Tis the way of the world! It is the same with restaurants- they never serve as good a meal after the first year or so! The good bargains last until...
Dear All, As I already had an open album at Yahoo Microscope and also because I had not seen any activity here for over a week I posted several diatom ...
Hi David, Admittedly, things have been from slow to stop here for the last week or so, but I would guess that it is a summer time thing. I know, at the best...
Stan, I posted two photos of the Spencer on your photos section. The photos also appeared in a short article I wrote on the Spencer for MICSCAPE. As to the...
Thanks, David, I changed the picture on the groups home page, check it out, your Spencer will well represent the group. Quick question; I can understand the...
Stan, I was extreamly lucky! I have three slides from McMurdo Sound, one from the Challanger Expedition to Kergulen Island, several of Oamaru fossil species,...
Hi Gregg, Arthur, and anyone else with answers, I just found another gray Dynazoom, but have no idea of what the condenser setup is for. It looks like the...
Hello Stan, Gee - testing my memory on that condenser - not ringing any immediate bells for me - not sure why the front element would be fixed - perhaps Arthur...
Gregg, I'm going to have to agree with you, this condenser does not ring a bell. Stan, where are you finding this stuff? I am by no means a B&L expert. In...
Thanks, Gregg and Arthur, First, the condenser; tomorrow, heaven willing, I will post a few pictures of it in my photo file. It is definitely B&L original ...
Gregg and Arthur, OK, no pictures yet, but Pat, my wonderful wife, came up with an answer, "why not use Arthur's cube to see what is going on" Bless you, ...
Gregg & Arthur, ETAL, I have posted the (odd) Dynazoom condenser pictures in my photo folder; 0004- Stage top with permanently mounted lens. 0005- Rack...
Faskinatin', Stan! I have never seen that configuration before, and still have no clue on what it could be used for - conoscopic microscopy, perhaps?? Gregg ...
Hi Gregg, Faskinatin, indeed! I can just hear Arthur's response now, when I ask him for some, periodic gratings, for my conoscopic microscopy. :-) It is nice...
One of our silent members is looking for a replacement for an objective or someone that can repair the one he has that is fogged up. He needs a: Reichert Epi...
The black Dynazoom I had -- and just sold on eBay -- had a normal condenser, with a slide-in auxiliary lens below to fill the low power field. However, the...
