The Labculture Reverse Horizontal Flow Cabinet (RHL) protects the operator and the laboratory environment from particles, aerosols, powders and allergens. The large volume of horizontal inward airflow provides equivalent protection with superior access into the work zone compared with Class I Microbiological Safety Cabinets, fume cupboards or related containment devices. This cabinet does not provide protection against chemical vapors nor protect the product from exposure to contaminants. Suitable applications include animal handling (where product protection is not required), powder containment, sputum induction and others.

Key Benefits:
  • Advanced airflow monitoring
  • Conveniently large work opening
