Top Loading Priorclaves

Vertical autoclaves can accommodate the tallest flasks, fermentors, and bioreactors at 1/3 the price of a comparable front-loading unit. Compared to similar-sized medical-grade rectangular-vessel units, cylindrical autoclaves are easier to operate, less expensive to maintain, and more reliable over a longer working life.


  • Easily accommodates the tallest flasks, fermentors, and bioreactors, they’re also excellent for waste processing, especially in large batches (pop the lid and drop in the bag, just like a trash can).
  • All top-loading sterilizers can be outfitted for “gravity” or vacuum cycles, with in-chamber or independent heating.
  • Includes a stainless steel load support plate and stainless steel mesh baskets for optimal steam circulation.
  • All models include the most current version of the fully-programmable Tactrol Control System.
