Supplier: Thermo Scientific
These biological safety cabinets offer high levels of safety for users and product. They are ideal for use in fields such as biotechnology, microbiology, research, laboratories, pharmacies and hospitals. They are compliant with safety levels 1 - 3 as required in microbiology, biotechnology and gene technology applications.

  • Aerosol-tight electric front window provides ease of sealing for fumigation and a clean sterile environment when the window is closed
  • Sash opening: 254 mm
  • Main and exhaust HEPA filter 99.999% efficiency for 0,3 µm particles (type H14 according to EN 1822) pre-stage filter 85% efficiency for 5 µm particles

Their ergonomic design allows unobstructed, all-round visibility with frameless front window and transparent glass side windows. The front opening is over 250 mm to enable convenient handling. Corners on the inside are rounded and windows can be folded up completely for easy cleaning. Air supply and exhaust is controlled automatically by the ventilation system. The display on the back wall of the workspace is placed at eye level, so that all parameters and operating functions can be monitored comfortably. Optional connections for gas or other media are provided on the side or rear walls. These cabinets are equipped with ergonomically designed arm rests.

With advanced internal airflow and motor technology, HERAsafe® KS cabinets offer optimal energy efficiency, operation and serviceability. At full speed the motors consume 60% less energy than standard cabinets. To further conserve energy, the intelligent speed control automatically reduces blower speed to 30% when the window is closed. This technology extends HEPA filter life while ensuring a sterile working environment and saves energy to minimise operating costs.

Certifications: Certified according to EN NF 12469.
