Ultra Yield 125mL Flask

Ultra Yield® Flasks are sterile, single-use shake flasks engineered for max oxygen transfer and high-density growth. Their high-aeration geometry, used on standard orbital shakers, drives faster cultures and cleaner downstreams. Pair with AirOtop® Enhanced Seals or Vented Screw Caps; with Plasmid+® Media, customers have reported plasmid yields up to 610%. Key features
