Cool Pharmacy Tech – PowderSafe Type A Enclosure

Every Friday I receive a weekly newsletter from And every Friday I spend a few minutes skimming over the newsletter looking for interesting things to read. Yesterday was no different.

I still find extemporaneous compounding interesting and like to keep up with what’s going on when I can. Like most newsletters this one contains a little advertising scattered throughout the document. I typically don’t pay much attention to the advertisements, but this week one of the advertisements caught my attention. It was for the PowderSafe Type A Enclosure by AirClean Systems. It’s basically a small tabletop laminar flow hood used for extemporaneous compounding.

Compounding pharmacies make a lot of custom medications from powdered ingredients. Depending on the physical properties of the powder being used they can be quite “fluffy” and generate a lot of particulate matter in the air. And the last thing you want to do is spend your days breathing in various powders that may ultimately lead to problems.

From the AirClean Systems website:

AirClean® Systems PowderSafe™ Type A enclosures provide an effective and safe environment when using powder weighing equipment in conjunction with toxic compounds or chemicals. SafeChange™ technology minimizes the threat of exposure to toxic powders during pre-filter replacement. The electrostatically charged pre-filter is easily bagged out under negative pressure.
