BMB-III-Laminar-S PROTECT VIS-A-VIS

Class III PROTECT VIS-A-VIS

 

Article 1Е-С.002-12.0

The cabinet is designed for operators working simultaneously opposite one another.

If connected to the individual active exhaust system, the cabinet could be used for protection from small amounts of toxic chemical substances and radionuclides.

The system of monitoring with the audio-visible indication system warns operator about the failure of working modes in the cabinet.  

 

 

Application of the Biological Safety Cabinet Class III:

  • Protection of an operator and environment from airborne infection when working with pathogenic biological agents (PBA) and microorganisms including highly (especially) hazardous pathogenic groups. 
  • Protection of the work agents inside the work chamber from external contamination.
  • If connected to the individual active exhaust system, cabinet can be used for work with toxic chemical substances and radio nuclides in low quantities and for odor removal from the work agents.
  • Cabinet is designed to equip workstations in the medical, pharmaceutical, and other institutes working with microorganisms of I-II-III-IV pathogenic groups and with parasitic disease agents 

Main Features

Chamber

  • The work chamber made of 1.5 mm stainless steel;
  •  Front sash can be lifted for equipment loading. It is made of triplex and is supplied with two glove ports. Sash is resistant to UV-light and disinfectant solutions.   
  • Each glove port is equipped with a butyl chamber glove and a silicon sealing O-ring. Features of the gloves: high impermeability (water, gas, vapor), used at wide temperature range, resistant to solvents and high-concentration acids, used for medical, pharmaceutical, chemical and biotechnological research.
  • Ten liter liquid gathering tray without draining neck is located in the bottom of the chamber.  
  • two work chamber LED lighting units;
  • Removable electrical sockets in the work chamber (on the left side wall);
  • UV light inside the chamber;
  • Pressure gauge of -500 Pa to +500 Pa .

Purification System of Supplied and Exhausted Air

  • Filtering system of the air supplied to the chamber has two steps: preliminary coarse filter G4 and plenum НЕРА-filter Н14 located above the work chamber;
  • Two-step filtering system of the air exhausted from the work chamber is executed through two consecutive HEPA filters Н14;
  • Supply and exhaust filtering module for removal of the air from the chamber is supplied with two fans. 

 

Pass Box

  • Outer panels of the pass box are made of metal covered with powder enamell;
  • Inner chamber is leak-tight and made of 1.5 mm stainless steel; 
  • Angular door location: outer door is in front, inner door is built into the side wall of the work chamber;
  • The doors of the pass box are equipped with latch handle made of 5 mm stainless steel;
  • The doors of the pass box are featured with electromechanical handle locks preventing simultaneous opening of both of the doors ;
  • Windows of the pass box are made of tempered glass.
  • LED lighting of the pas box;
  • UV light;
  • Pullout tray made of stainless steel ensuring easy transferring of the objects from the pass box into the work chamber;

Control System

  • Microprocessor control system of the electroautomatics;
  • Cabinet’s control unit is a  touchscreen;
  • Sluice control unit is a button box with indication of sluice’s doors and locks statuses;
  • Air balance parameters sensors;
  • Built-in power cord;
  • Separate safety devices for fans and removable sockets;
  • Switch for removable sockets unit installed in the work chamber 

Control Elements of Air Flow Parameters

  • Built-in air-sampling outlets for testing the HEPA filter integrity

Class III biosafety cabinet options

  • self-contained module for testing the glove integrity
