Today a colleague
asked for my opinion of the fume hood related device described at http://www.isolationsciences.com/home.html.
This is an insert that roughly converts a standard chemical fume hood to a glove
box - but with no glove in, or intended to be in, the gauntlet openings. This
reduces the face opening and permits substantial reduction in ventilation
volume.
The concept is
intriguing and I wanted to ask if there is anyone on this list who has actual
experience with this device, and, if so, what that experience might
be.
My first thoughts
about possible drawbacks were about combustibility (not just flame spread)
and susceptibility to puncture or tearing when new or as it ages. I also
wonder about the possibility of accumulation of airborne contaminants in the
work volume as a result of the lower ventilation rates this
makes.
I would appreciate
you insights based on actual experience with this or something
similar.
