Work sterile in plant tissue culture with laminar flow hoods

There are millions of particles floating in the ambient air. They may contain microbes such as viruses, bacteria, fungi and many more. Eventually, those floating particles will land on objects and create contaminations. For this reason, it is necessary to ensure clean and sterile airflow over tools, containers and specimens using proper air treatment equipment. In this case, laminar flow hoods, also referred to as laminar flow cabinets, are a must-have for any plant tissue culture laboratory as working sterile is the key for a successful operation.

How does a laminar flow hood work?

A laminar flow hood takes the ambient air and moves it through a pre-filter which will stop large particles. After that, a HEPA filter will remove most, if not all, contaminant particles from the air. Consequently, the filtered air is blown into the working space laminarly. The positive air pressure prevents contaminants from getting into the working space.

Airflow direction

  • Horizontal air flow hoods filter the air from outside the hood and blow the clean air from the back of the hood towards the operator. Undoubtedly, this type of laminar flow hood should not be used while working with hazardous or infectious materials since it does very little to protect the users.
  • Vertical air flow hoods not only filters the air from outside the hood, but also recirculates and filters the air from inside. Clean air is blown downward over the work space from the top. This direction of air flow protects both the users and the specimen thanks to the complete circulation of air within the work space.

For plant tissue culture purposes, people usually prefer horizontal air flow hoods because this will create a flow over the workspace and blow all the ”dirt” out of the cabinet. In addition, lab operators rarely have to work with hazardous materials. Due to the additional safety measures, vertical flow hoods tend to be more expensive in comparison to horizontal cabinets.

Standard laminar air flow cabinet

Our standard horizontal air flow cabinet features a minimalistic and clean design, while still offering all the advanced sterilization functions:

  • In-house developed accurate airspeed measuring system
  • Automatic airflow compensation
  • Built-in UV light for post-operation sterilization

Aside from those functions, our flow hoods guarantee a better HEPA filter life by using a combination of pre-filter and a recirculating system that recycle clean air in the back of the hood.

Advanced laminar air flow cabinet

On top of all features found in the standard version, the advance version of our horizontal air flow cabinet offers better build quality and automated features:

  • Motor-controlled window blind
  • Safety switch for UV light when front shutter-blind is open

Biosafety cabinet

The biosafety cabinet is our most advanced flow hood. As a vertical air flow cabinet, it provides optimal protection for both specimens and users. Therefore, the users have little contact with the airflow within the working space. We highly recommend customers who work daily with harmful material to use a biosafety cabinet.
Customers who purchase this model also enjoy all the features found in the advanced horizontal air flow cabinet, on top of the extra protection.

All our cabinets are available in three sizes:

  • 120 cm
  • 150 cm
  • 180 cm

Furthermore, these cabinets come with support stand.
