All,

 

We have operations where we only need to protect the product being tested and not the worker, mostly procedures where we are looking for very low levels of non-hazardous particulates on the surfaces of pharmaceutical containers.   Although we call the laminar flow units we use for these procedures clean benches, not hoods.

 

But we also have a hood we purchased from Air Control (Microvoid) that is used for ICP prep where we are looking for very low levels of metal ions.  It has both a laminar flow through a HEPA filter to protect the product/testing and also draws air into it, like a standard hood, to protect the worker.  It is constructed entirely of a polymer – no metal whatsoever.  We purchased it because our scientists felt that they were getting contamination from our regular hoods in their work.  It seems to alarm quicker than a regular fume hood… there is a lot more going on with the air flow… and it is also more challenging to do the annual PQ on it, we have to call in an expert.

For someone in my end of the biz where all our air contaminants have hazards, that was hard to comprehend.  I hope we really have exposure data and know for sure that besides being non-infectious, these DNA/RNA thingies also do not provoke allergies or have any other hazards.

Monona--think PCR with non-infectious DNA/RNA (RG1).  Or tissue culture with non-mammalian cells.....

best,

I'm confused:  On the first page of the link it says:

 

These vertical laminar flow Hoods are ideal for applications which are not hazardous to the operator but require a clean work area.

Shelly,
 
    From what I have seen, the Laminar Flow Hoods are one of the best on the 
market.  Performing Lockout/Tagout audits, I see a lot of the bench top vertical 
models.  Here is a link for your viewing.

I hope this helps you out.
 
Respectfully,
