Wanted: Info on Spiral dilution plater

[crawford at bscr.uga.edu]

I'm looking for vendor/pricing info on a spiral dilution plater - a 
device that dilutes a suspension of bacteria while dribbling it in 
a spiral pattern on a petri plate. It allows estimation of the 
initial titer of the bacteria as a function of how far "down" the 
spiral colonies appear after incubation.
I can't find it in any of the usual catalogs (Fisher, VWR, etc)

	Thank you for any help you can give me.
