"This design passes the flame test as shown in the picture above, even when it's not turned all the way up to max flow rate. "----"I purchased an expensive Met One laser particle counter to test filters for this project, and PROVE that they were working as expected. As far as I know, I am the first person to describe such a low cost laminar flow hood and also provide analytical testing showing that it works."----"I want to show video proof that the design works flawlessly, and I can tell you already that is the case as I've already made numerous agar dishes with a 100% success rate and even exposed open agar dishes to the flow for 5 minutes before closing them and waiting to see what would grow on them (nothing did!). That combined with the Met One particle count results are pretty irrefutable proof."
I have not tried it, but would if my situation 'allowed' it
If I were to do it I would use a hot knife cutting tool or hot knife cutting tool foam
( from amazon) also listed under or hot knife cutting tool plastic --as a Possible alternative to rotary cutting tool --May be less likely to crack the tote. If one does this, use outside because of fumes from melting plastic.---
