The actual PCR process is pretty innocuous, and does not involve any volatile or toxic chemicals. The phenol and chloroform might be used subsequently on the samples, but not in the machine. I cannot really see why the machine itself would need to be in a hood.
Hope this helps.

Some of the references I reviewed on this technique listed a variety of hazardous chemicals associated with this process (phenol, chloroform, etc.), but they are somewhat dated and I wonder if these machines use these chemicals.

From what I can see in the instrument manuals I downloaded, the ventilation needs seem to be limited to temperature control considerations, but I thought I would check with the DCHAS list to see if anyone has experience with chemical exhausts from these systems.
