Re: Zeiss Standard gets a new home

So, that's all running off the computer chassis? :) Yes, it is a common knowledge conversion of a computer PS to a psuedo bench power supply. (Although half the youtubers. etc get it wrong!) To be clear, the only component that is mandatory, in addition to a computer power supply, is the resistor y...

Re: Protozoa growth chamber

I was also fortunate to have a Gilbert microscope and also a chemistry set in my youth. (Although, like my youth, I didn't do much with them.) :-)

That is handled; I finally build the 12 volt power supply although I am not happy with the enclosures and will be redoing them.

It sold for $101. Like the Zeiss that I looked at (It too sold for a bit over $100 too at a SWAP auction), the condenser was worth more than the sales price.

Re: Please consider methyl cellulose for high magnification observations of active meiofauna and protists!

I would encourage curious members to give that preparation a try. It is pretty cheap and effective. Now that Fan has finished his analysis if anyone wants some, send me a PM and I will send it. There is no way I would ever use the pound that I have so you folks might as well help put it to good use...

Re: Please consider methyl cellulose for high magnification observations of active meiofauna and protists!

That is great news Fan! Thank you for testing. I believe you will find that the bubbles dissipate if you let the solution set undisturbed. As far as the mix, I will be using 1% or less. Didn't you find 2% to be too thick? Here is the link: http://www.amazon.com/gp/product/B001QQ7LOA?psc=1&redirect=t...

$2.99 Goodwill B&L Microscope

It operates like a stereozoom but with a compound microscope range of magnification!

I have read of professionals that clean their objectives only annually. Amateurs over clean, clean improperly and/or often damage optics.

That said, see if this helps:

I would have called it clear before you mentioned a normally yellow effect with starch. :-) I am having no luck with mixing the powder and water.

Re: Please consider methyl cellulose for high magnification observations of active meiofauna and protists!

Amazon review of methyl cellulose powder: Quote a 1% solution makes a thickish liquid like light cream and is a good liquid paste especially for paper. A 2% solution pours somewhat like honey but is the best for mixing with paint or pigments. Try a little at a time. I fill a squirt bottle with an e...

Glad you started this thread charlie g. I didn't realize so little methyl cellulose was needed! Since I have a pound in powder form, I will send a bit in an envelope if anyone needs some.
