I am trying to find where to buy thermometer microscope slide(s). The slide 
has a series of bars (one per degree Celsius), which change color when each 
bar's temperature is reached.

No success through Google, two linkedin groups, or searching the MSA 
microscopy listserv or confocal listserv. Someone at linkedin suggested that 
Reichert used to make them. Fairly common in cytogenetics labs. 

thanks in advance,

George
