I was not knocking your glove box - at all. More power to you.

After fooling with a glove box, I built this big puppy.

Contam rate is about the same, but it sure is a lot more comfortable to work in. But, it takes up as much room as an office desk & is not very portable.

What is funny. I get about a 5% contam rate working in a well sanitized bathroom, using Oust, a mask, gloves & hair cover. With the glove box or flow hood, the contam rate lowered to around 2%.

All in all, a well sanitized bathroom, with heat vent closed, good procedures & equiptment is ALMOST as effective as a glove box, or flow hood (at least for me).
