Dear members,

Thank you  so much for all the responses to my question on : containment and safety in weighing dry Nano materials.

We will be looking at a hood from Flow Science with Bag in and bag out system in the case one filter fails. The regional salesman will be bringing a demo hood for my research group to  try out with their balance.   You all are right:  this field is still so new and researchers are so excited to try out new methods. WE IH people tend to be nervous about the full extent of the toxicity of such compounds using conventional methods, in this case, on the lab benches!  

Thank you again for all  your insights into this matter. Your help was invaluable.  Have a great weekend.
