BMB-II-"Laminar-S."-1,2 SAVVY SL CYTOS Class II

Article  2Е-B.013-12


Biological safety cabinet Class 2  Cytos  is designed for work with cytostatic and cytotoxic agents.

The cabinet Cytos provides product, operator and environment protection for work with agents of biosafety levels 1, 2 and 3.

Application of the Microbiological Safety Cabinet 

  • Personnel protection from exposure to antineoplastic (cytostatic and cytotoxic) compounds when working with such;
  • Aseptic preparation of the antineoplastic (cytostatic and cytotoxic) products
  • Physical isolation (containment and controlled removal from the work zone) of pathogenic biological agents (PBA) and microorganisms to prevent airborne infection of the staff and contamination of the air in the work room and to protect the environment.
  • minimization of risk of contamination and cross-contamination of the product;

  • the cabinet is used to equip individual work places in medical, pharmaceutical and other institutions working with pathogenic biological agents and microorganisms;
  • the necessity of the cabinet connection to the exhaust system is determined individually by the exploitation organization judging on the analysis and assessment of the risks. In case of the cabinet connection, it must be provided the exhaust ventilation system capacity of 750-1000 m3/h.
  • If the cabinet is used for work with pathogenic biological agents (PBA) and high-risk (especially hazardous) microorganisms, a corresponding protective (antiplague) coverall shall be used.

Key Benefits 

  • Extra measures for operator and environment protection are provided in Cytos cabinet. Four intermediate cylindrical HEPA filters H14 are installed parallel to each other and located under the work chamber worktop. FILTER REPLACEMENT IS PERFORMED WITH WORKING FANS through the work chamber without additional dismantling of the cabinet. Therefore it minimizes the risks of personnel and environment contamination.
  • The table top is a quick-removable tray to ease up the collection of spilled materials, the tray under the table top prevents liquid leakage inside the cabinet.
  • The system of monitoring the cabinet's operating modes warns the operator about the air flow imbalance in the work chamber with an audible-visible alarm.
  • A unique pull out UV-unit is included into the basic configuration. 

Standard Features of the Microbiological Safety Cabinet

Work Chamber

  • power-driven sliding fron sash made of laminated safety glass;
  • side windows made of tempered glass;
  • slanted front surface of the cabinet;
  • work chamber LED lighting;
  • two electric sockets in the work chamber (in the right part of the rear wall);
  • airflow laminarization screen made of polymer micromesh;
  • removable tabletop (operating middle section, two side sections and one rear section) made of mirror stainless steel (AISI 304);
  • work chamber tray made of stainless steel (AISI 304);
  • removable armrest made of stainless steel (AISI 304)

UV unit

  • pullout (when inoperative, is stored outside of the work chamber under the tabletop);

  • metal grille protecting the UV lamp;
  • dampers against any impact upon lowering the work opening screen.

Ventilation System

  • three fans in the upper filter fan unit and three fans in the lower filter fan unit ensuring airflows inside the cabinet

Supply and Exhaust Air Filtration System:

  • the inner and exhaust airflows pass two-stage filtration ensured by:
  • one supply HEPA filter H14 located above the work chamber;
  • four parallel preliminary cylindrical HEPA filters H14 located under the tabletop;
  • one exhaust HEPA filter H14 located in the upper ventilation chamber.

Exhaust Hood

  • removable exhaust hood for connecting the cabinet to the active exhaust system;
  • joint clearance in the exhaust hood preventing any impact of the exhaust system on the cabinet operation.

Control System Components

  • microprocessor control system;
  • touchscreen control panel;
  • airflow sensors;
  • front sash and UV unit position sensors;
  • individual fuse for power supply to the main functions of the cabinet (fan, lighting, UV lamp);
  • individual fuse for electric sockets of the work chamber;
  • fixed power cord

Additional Components:

  • caster wheels for cabinet relocation;
  • screw supports for cabinet fixation at operating site.

HEPA Filter Integrity Testing Components:

  • outlets located in the left part of the rear wall for testing the supply and exhaust HEPA filters as well as preliminary HEPA filters.
