Still Air Workstation — 24" | Dead Air Box for Agar & Tissue Culture

There is nothing between a $75 tote bin and a $2,900 lab cabinet. This is that thing.

If you do sterile transfers, you already know the choice. You can hot-knife arm holes into a storage tote for forty dollars and live with a box that flexes, scratches and never quite seals at the lid. Or you can spend $1,600 to $4,450 on a bonded acrylic glovebox from a lab-furniture brand that freight-ships fully assembled.

The construction at the top of that range is quarter-inch plastic panels. That is what we cut every day. We flat-pack it instead of bonding and freighting it, which is where their cost goes and why we can land in the middle.

How a still air box actually works

It does not filter. It eliminates air movement. Airborne mould and bacterial spores are heavier than still air and settle out within a minute or two of the box being closed. A sealed enclosure with arm ports stops your own body plume and room drafts from carrying those spores onto an open plate while you work. That is the whole mechanism, and it is why the box has to be rigid and actually closed — a flexing tote pumps air every time you lean on it.

Specification

• ✅ External 24" W × 20" D × 20" H — fits a standard two-plate workflow with room for a burner or bead steriliser
• ✅ Polycarbonate, not acrylic. See the material note below — this is deliberate
• ✅ Two 6" gasketed arm ports in the front panel
• ✅ Lift-off top for full-width loading and wipe-down
• ✅ Coved deck with a wipe-clean floor and no trap corners
• ✅ Oversized, chamfered fastener holes and compression gasketing at every joint
• ✅ Flat-packed. Assembly is 60–120 minutes with the included hardware

Why polycarbonate, and why it matters more than the price

Your workflow is spraying 70% isopropyl on every surface, several times a session. Stressed acrylic crazes under IPA — fine hairline cracks that start at bolt holes and bracket joints, which is exactly where a panel-and-bracket design puts stress. Plenty of vendors sell acrylic gloveboxes anyway and let you find out. We build the wetted panels in polycarbonate, oversize and chamfer every fastener hole, and use compression gaskets rather than tight bolts. It costs us more. It is the difference between a box that lasts and a box that spiderwebs in a year.

Straight talk about what this is not

This is a dead air box — a still air workstation. It is not a biosafety cabinet. BSCs require NSF/ANSI 49 certification, HEPA filtration and validated airflow, and we carry none of those. We make no sterility, air-change or contamination-rate claims. If you are working with anything that requires containment rather than exclusion, you need a certified BSC and we will tell you that rather than sell you this.

Who buys this

Gourmet and specialty mushroom growers, plant tissue culture, cannabis TC, community and teaching labs, small biotech, reptile and insect breeders doing sterile work. If you want UV-C, ask — we can supply it as a kit, but read the note on panel life first.
