Re: Doing Diatoms a Different Way

Welcome Jacky! Good you made it over here! I use capillary tubes over an alcohol burner with no soot. I would probably break my tips trying to clean the off. I have a system where I twist and work the capillary tube over the flame until I have a solid middle and then do the pull as I'm coming off th...

And to think that when they first came out brand new, fully loaded, it probably cost around $10,000...the price of a small car.

Re: Doing Diatoms a Different Way

I haven't sold any as of yet but I have sent some prepared slides of diatoms to people in exchange for sample material they have sent me from overseas. I make them type slides from the sample they send me.

Re: Weekend with New 'Scopes

I'm loving this comparison. Things which may make a difference: 1. There is a lighting difference...one LED and the other 30W tungsten. I wonder if you put the LED one in the back of the Zeiss if you see an improved difference than the tungsten light. 2. Filters in place. The Zeiss has in base filte...

Re: Doing Diatoms a Different Way

Just updated my setup: B&L StereoZoom 7 with 15X eyepieces, 1.5X auxiliary lens which now gives me 157X max magnification. I finally found the 1.5X B&L auxiliary lens for a reasonable price. The addition of the 1.5X auxiliary lens and extra 52X magnification really makes a difference checking out sm...

For the stage, you probably won't need to go beyond taking the top of the double layered stage off and clean the old grease from the rails (in red), the gear (circled in red) on the lower section and the corresponding areas on the top piece including track. Regrease lightly with a light grease. Zeis...

I think you should get at least $200 back, but start by telling him you want $250 back. The...

I may have one...will need to check the spare trinocs I have, to ensure they are suitable. Even with the trinoc head, you will also need the proper phototube. I think there are still some on ebay.

Re: Brasso

I do believe that the "copper" coating, which you refer to, is actually just the lacquer which Apo refers to. As the lacquer ages, it also can get darker. The Brasso is taking the lacquer off along with with blemishes and it also will take paint off, so you need to be careful. After getting down to ...

Re: Zeiss Axioskop 50

I would agree. It all depends on what is on the scope. If it is loaded (Phase, DIC, Neofluar or Apo objectives) and a good price, it would be a good option, but upgrading can be very expensive. Just the APlan infinity objectives cost $200-300 each. Neofluars, PlanApos, Phase, cost hundreds to thousa...

That is a very good point. Also the IIIRS Fluoro unit also has an 'Open' selection which allows you to use regular transmitted light through the unit.

That has the IIIRS epi-fluoro unit with both HBO and halogen lighting. The condenser is a Phase condenser and it also has a nice circular stage. Here is one which just popped up with circular stage, phase condenser and looks like the better Neofluar objectives. https://www.ebay.com/itm/Zeiss-Lab-Mic...

Also, You can use any regulator/transform which can step up the voltage from 6-12V for the tungsten/halogen lamps, but the HBO 200W mercury lamps use separate 110/220V regulator.
