The Stuart Charcoal Gel transport swab combines a long narrow transport tube, fitted swab applicator and a short column of opaque charcoal-containing medium. It is a microbiology transport device—not a vacuum blood collection tube—and should be selected only when the validated protocol calls for Stuart with charcoal.

Product Highlights

• Stuart semisolid transport medium with charcoal.
• Long narrow tube format designed around a specimen swab, not phlebotomy.
• Fitted cap and applicator support closed post-collection transport.
• Swab tip, sterility, shelf life and pack quantity are confirmed by SKU.
