Introduction de produit

The smallest retained biosafety pass box provides a 457 mm cube for hand-carried loads. Its closed-loop HEPA circuit cleans chamber air without drawing from or exhausting to the adjoining rooms, reducing disturbance to their pressure balance.

Key Features

Compact load volume

The chamber suits small sterile samples, carriers and supply packs.

Room-pressure isolation

Closed-loop airflow avoids a continuous exhaust path between adjacent spaces.

Stainless material choice

304 or 316L construction can match the cleaning environment.
