[labnetwork] Methods/tools for removing wafers/pieces from hot platen (hot plate or CVD system)

[Albert William (Bill) Flounders]

 Bill Kiether,
I recommend you search for "pizza spatula", "pie server"and other SS
kitchen tools.
Several of these tools have an offset handle that is very helpful.
You can sharpen the front end or evaluate purchase of a "bench scraper" or
"scaper / chopper" or "rocker cutter" and use the two tools as a pair.
In general kitchen supply companies have a wide range of tools that are
useful in the lab.
They are good quality, non particulating SS, designed for dextrous use etc.
Also, our french fry warmer is superior to any lab glassware dryer.
Bon appetit
