Laboratory Project >> 
Professional laboratory design and construction company, successful partners have quality supervision, measurement, schools and other units.

 
Our implementation of the the FS209E U.S. federal standard, ISO 14644-1 international standard, GB50073-2001 national standards, the pharmaceutical industry clean room cleanliness standards GMP-97 and the national GMP, the QS regulatory requirements to provide customers with a professional air purification systems and laboratory engineering design, construction, testing and technical support services, according to the customers the technical requirements for clean room systems and planning and design of the actual site conditions, construction and production of professional cleaning equipment [main products include: dust in addition to the electrostatic purification equipment, automatic / cargo Airshower , pass box, clean benches, purification production line, HEPA Fan Filter Unit (FFU), dust collector, mobile self-purification, clean lockers, dehumidification purification machine, modular air handling units and other purification equipment and high efficiency filter, medium filter, sub-high efficiency filter, primary filter, smoke and air filter, etc.].

 


Biological safety cabinet installation


A biological safety cabinet, if the trachea and water pipes should be installed.


2, when closed within the exhaust manifold and the shaft of the multiple biological safety cabinets exhaust riser connected manifold should be used backflow prevention device, and from the riser entrance up stretching at least 0.6M.


3 biological safety cabinet is installed in place before connecting the exhaust pipe to cope with the high efficiency filter installed border and the entire filter surface scan leak. When zero leakage of the exhaust device to deal with the leak of the filter surface.


4, the manual in the use of pressure regulating valve constant air volume system, when multiple safety cabinet exhaust parallel, the whole system after installation in a safety cabinet should be re-balanced, using pressure-independent air volume balancing valve can not do this balance.


5, biological safety cabinets installed and leak detection should be carried out following site inspection.


① Level II safety cabinet is installed, the operating area of ​​the air flow rate should be testing, should recognize the results of the current national standard biosafety laboratory construction holding technique specification requirements.


② The I, Class II safety cabinets installed for the inspection of the work window airflow direction should confirm all point to the cabinet air flow through the entire operation.


③ I, class II safety cabinet installation should be working window air speed test should confirm that the results meet the current national standard biosafety laboratory construction holding technique specification requirements.


(4) grounding device, grounding line resistance test should confirm that the resistance of the grounding of the branch circuit wiring and socket does not exceed the design requirements.
