模擬血液濃縮液（不染色）- 1加侖

We use this for our annual mass-casualty drills, and the fact that it doesn’t stain scrubs or the gym floor is a lifesaver. Mixed up a whole gallon in about five minutes and the color stayed consistent through two hours of sweaty role-play.

Mixed this concentrate to the exact ratio on the label and the color and viscosity were spot-on for our trauma drills. The non-staining claim held up even on white uniforms after a full afternoon of bleeding-control practice, which saves us a ton of laundry hassle.

The non-staining claim is the real deal—I sprayed this on a tourniquet trainer and it wiped off the floor with just a damp rag. The gallon size also means I've got plenty left for the next few drills.
