The key to successfully using something like this would be to ensure that EACH unit has sufficient exhaust volume and capture velocity.  A system designed to provide local snorkel ventilation may not provide enough exhaust volume for any sort of open face enclosure.

You might try searching for Plexiglas balance draft covers.  They sound about the right size but you would need to modify the back panel.  I googled Plexiglas balance covers.

Hi,

 

I don't know if such a thing might exist, but I want to ask just in case. I'm looking for an "adapter" of sorts that would sit on a benchtop and sort of contain an experimental setup under existing snorkel ventilation.  At my home institution, we have something like this.  They are plexiglass boxes about 18" tall, 14" wide, and 16" deep, open at the front cut out in the back for a bench-level ventilation in-take to fit.

 

This lab room is at another local institution and hosts an undergraduate Organic Chemistry course that works in microscale so the amount of fumes will be limited, but none the less best ventilated externally.

 

Hoping to get a lead,

Thanks,
