BMB-II-Laminar-S-1,5 with extended work chamber

Article 1E-B.007-15.0 

 This modification of the cabinet has extended height and depth of the work chamber.

Application

  • 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 laboratory environment;
  • minimization of risk of contamination and cross-contamination of the product;
  • the cabinet neither protects from toxic chemicals and radionuclides nor contains work agent odors;
  • possibility to work with small amount of toxic chemicals and radionuclides as well as to remove work agent odors in case of mandatory connection to an active exhaust system using an exhaust hood supplied upon customer’s additional request;
  • the cabinet is used to equip individual work places in medical, pharmaceutical and other institutions working with pathogenic biological agents and microorganisms

 WorkChamber

  • hinged front sash made of laminated safety glass; opening, closing and upholding is carried out by gas springs;
  • two dampers against front sash closing impact;
  • 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 left part of the rear wall);
  • airflow laminarization screen made of polymer micromesh;
  • air intake grille in the rear wall of the work chamber;
  • three-section tabletop made of 1.5 mm mirror stainless steel (AISI 304) with air intake grille in the front;
  • work chamber tray made of 0.8 mm stainless steel (AISI 304);
  • removable armrest made of 0.8 mm stainless steel (AISI 304)

UVUnit

  • 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.

Supply and Exhaust Air Filtration System

  • supply air coming into the work chamber is cleaned by supply HEPA filter H14;
  • exhaust air coming out of the cabinet is cleaned by exhaust HEPA filter H14;
  • three fans ensuring air supply into the cabinet;
  • one fan ensuring air exhaust from the cabinet.

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;
  • built-in power cord

Testing and Adjusting Components:

  • built-in outlets for sampling the air upstream of HEPA filters for their integrity testing (located in the right part of the rear wall).

Stand:

  • frame stand with footrest;
  • caster wheels for cabinet relocation;
  • screw supports for cabinet fixation at operating site.
