CTH

Biohazard Safety Cabinets (BSC) are used in all those situations where it is necessary to protect the operator and the environment from harmful effects deriving from the uncontrolled spread of airport contaminants and, in equal measure, until no environmental interference of a microbiological nature involves and compromises the product during its manipulation.

Normally used in hospital pharmacies, oncology department, day-hospital and pharmaceutical industries.

For a correct use and application of the cabinet here described, it is necessary to refer to the appropriate standard norm and rules in force in the country where the cabinet is used. The main standard for product in Europe is a German Standard DIN 12980.

 





CTH C2 produced by ALS is a triple absolute filter cabinet and it is defined:

Class II as designed with a frontal working opening for the aspiration of 30% of the total air involved, at a minimum velocity of 0,40 m/sec., and the remaining 70% is recirculated through a HEPA filter in the working chamber with a laminar flow velocity between of 0,25 and 0,5 m/sec (as defined by DIN 12980 and by EN 12469).

 

Specifications

 

  • External structure in epoxy powder coated cold-rolled steel for excellent corrosion resistance to the attack by aggressive common chemicals.
  •  Rear wall in stainless steel AISI 304 L, designed to conform to requirements and pass the “cleanability test” according to EN12469:2000.
  • Work surface in stainless steel AISI 316L in one piece (or by sections upon request) which are easily removable for carrying out routine cleaning and/or autoclaving sterilization procedures; closed or perforated on request.
  • Work chamber in single piece AISI 304 stainless steel for the best cleanability.
  • Front window: Stratified hinged safety glass to give easy access to large items. It is provided with gas springs to keep it open during maintenance or sanitization operations.
  • Re-circulating and extractor fans: two centrifugal fans direct driven motor (main and exhaust), with protection factor IP-55, controlled by two automatic independent speed-flow rate regulators and microprocessor system to keep constant airflow, showing laminar flow and protection barrier work conditions.
  •  Filtration: H14 HEPA/ULPA filters with an efficiency better than 99,995 % MPPS (EN-1822). Third bank of class H14 HEPA/ULPA filters with easy replace system is positioned beneath work surface built for handling cytotoxic drugs
  • Operation Condition: Air cleanliness in Class ISO 3 as per ISO EN 14644-1.

 

The user-friendly practical keyboard and the rear-lit LCD will continuously display all required data keeping the user constantly informed of the cabinet conditions in operation
