How to Clean the Laminar Flow Hood


Cleaning Ossila Vertical Laminar Flow Hood

To ensure the cleanliness of your laminar flow hood, it is essential to use the following steps:

  1. Begin by applying a disinfectant spray to the air at least 10 minutes before commencing any work. This step serves to neutralize charges on colloidal particles, causing them to precipitate from the air.
  2. Immediately before commencing cleaning, thoroughly spray the hood's surfaces with a suitable cleaning solution, such as a 70% ethanol solution or an 80% isopropanol solution.
  3. Use a clean room tissue or a microfiber cloth to wipe down all surfaces. It is crucial to start with the cleanest areas and progress towards the dirtier sections to prevent the spread of contaminants. In the case of a vertical laminar flow hood, begin by cleaning the back wall. If using a horizontal laminar flow hood, the ceiling panel should be addressed first.

  4. Clean the side walls by moving your cloth or tissue from side to side, working from top to bottom.
  5. Always leave the floor panel to be cleaned last. Again, follow a motion from the back to the front. During this phase, make sure to change the cloth or tissue regularly.
  6. It is vital not to attempt to clean the filter panel, as this could disrupt the laminar flow hood's functionality and contaminate your workspace.

How to Assemble the Vertical Laminar Flow Hood

Our laminar flow hoods arrive flat-packed. This gives you the flexibility to set up your unit in either a vertical or a horizontal configuration, and switch between them if needed.

Assembling your laminar flow hood in the vertical configuration is easy and can be achieved in six main steps.

Replacing Your Laminar Flow Hood Filter

Clean and sterile environments are required in many areas of research. Laminar flow hoods play a crucial role in creating these environments. They rely on high performance filters to remove particles from the air before it flows through the workspace. Laminar flow hoods use pre-filters and high efficiency particulate air (HEPA) filters to create an environment with very low levels of contamination.

It is important to know when and how to replace these filters, without risking contamination to the environment.
