Cell Roll System

The optional cell roll system (shown installed within the incubator chamber) allows extensive production of monolayer cell cultures in standard roller culture vessels.

  • Improves oxygenation and exposure of the cells to the media growth area
  • Increases culture yields by the uniform temperature control and cellroller system's continuous, gentle rotation
  • Accommodates a cell roller up to 7 decks high with 5 positions per deck—maximum total of 35 positions or bottles.
  • Requires three tier models 4862 or 4868 to achieve maximum capacity:
  • three tier cell roller base (15 positions)
  • four add-on tiers (20 positions)
  • and a reinforced floor/ramp to achieve

Directed Horizontal Laminar Airflow System

  • Promotes ideal growth environment by releasing positive pressure feed plenum on the left side of the chamber and a negative pressure return plenum on the right side
  • The combination of airflow directs air across the surface of each solid shelf
  • Each shelf receives a consistent flow of conditioned air when filled with samples or equipment
  • Chamber contents will not block feed plenum
  • Minimizes risk of product desiccation and loss
  • The directed airflow saves time and money by minimizing the risk of product desiccation and loss

Applications for Heratherm Advanced Protocol Security Microbiological Incubators
  • Clinical and Medical labs: microbiological diagnostic testing
  • Pharmaceutical: quality control testing, safety and testing efficacy of manufactured products
  • Food: screening for bacterial contamination
  • Research and biotech labs: bacterial growth, gene expression studies, production of recombinant proteins


Directed airflow passes over the surface if each shelf, ensuring temperature uniformity throughout the chamber.
