BD Falcon 15 mL conical centrifuge tubes deliver reliable performance for equine semen collection and processing. Made from high-clarity polystyrene with dark blue printed graduations and a white writing patch, they support accurate measurements and easy labeling. A polyethylene plug-seal screw cap provides a positive seal over the full circumference, while medical-style packaging better assures sterile presentation. Sterilized by gamma irradiation and nonpyrogenic, this 50-pack on rack is ideal for veterinary, horse, and equine breeding labs.
