are there any tools for chemistry block diagrams

[madatcad]

I am trying to make a flow diagram showing various lab equipment. Is there a Autocad library available or an alternate software package?

for flow diagrams in general I have enjoyed using this program

and the best part is that it is free!
I don't know if it contains lab equipment diagrams that you are looking for.

Thanks Thalon,
It did not have the lab equipment diagrams I was looking for, but I was also looking for a general flowchart program and this will work for that. I am still looking for a lab version.
