Equipment+-+Laminar+Flow+Hood

"Glove boxes are considered "old tech". To retrofit a glove box into a laminar flow hood, simply cut out the back panel, replace with a similarly sized HEPA filter and build a 6"-deep plenum behind the filter. A squirrel cage blower is mounted on top, forcing air into the plenum. Air is forced through the filter. Downstream from the filter, a ster ile wind flows in which inoculations can be conducted." - Stamets
