Angular blast shields are available for this purpose. We incorporated the use of this when we had to run our Hydrogenator (the good ‘ol Parr Shaker!)

A VBE (Ventilated Balance Enclosure might work as well.

 

But I would like to know why can this line (sounds like a Schlenk line to me) cannot be used within the hood?

 

Hope this helps.

 

Cheers!

Subject: [DCHAS-L] Shielding for large vacuum-manifold?

 

[Multiposting.  My apologies if you’re seeing this in duplicate.]

 

Has anyone seen, developed, or researched solutions for shielding laboratory-scale vacuum manifolds for pulling high vacuum on glass vessels?  This would be a large (approx. 10-foot wide) glass manifold that would not be located inside of a fume hood.  We want to reduce the hazard of flying glass in the event of a glassware failure and resulting implosion. 

 

While this particular apparatus is part of a renovation for a new research group, we have some similar equipment on our academic campus that could benefit from the same kind of solution. 

 

Sliding panels/doors?  Enclosures?  Hanging blast shields?  Anything like this in use?
