I was wondering if anybody can explain what qualitative difference  
exist, if any, between different brands of plain glass slides. For  
example, over on the Ted Pella page ( http://www.tedpella.com/histo_html/slides.htm 
  ), for a 2-box pack of 144 slides, the price varies from about $10  
for the Pella Economy Slides, all the way up to $40 or $60+ for Gold  
Seal or Corning slides.

My question is, is there any advantage or optical difference with the  
more expensive slides? Corning advertises theirs as "water white"  
glass, which I imagine implies something about the transmittance or  
refractive index, but I'm not sure.

Dear Peter
It's all about the ions in the glass and relative composition of it's components
I'm on a trip  but when I ve time  I post a link

Thanks
   Cheers

Axel

If you go to www.proscitech.com.au (no connection) you'll find it all
explained.

Differences are such things as colour, flatness, precision and lack of
autofluorescence.  

You need to be doing very demanding work for it to make a difference,
but it's nice to know the expensive ones are there when you need them.

While you're on the topic of cover glasses, I am wondering if people have
suggestions for economy brands that consistently give "clean" products.  I have
been disappointed by the glass chips (50-100um) that are dusted over the
surface of many brands.
thanks,
