Laminar Flow Hood


The laminar flow hood, also known as a clean bench, provides a working environment with low levels of airborne contamination.

Our laminar flow hoods deliver consistently clean air, free of dust and contaminants, to protect your experiments. New smart air sensing technology monitors and provides live feedback on air quality, using pressure, temperature, and particle count data.

Ideal for a range of applications in which the sterility, integrity, and purity of your samples and workspace are critical. We have created a versatile and interchangeable clean air system that can be adapted to your research needs on any lab bench. And if you need support, our laminar flow hood resources are available to provide troubleshooting tips, application guidance, and maintenance advice.

Horizontal Laminar Flow Hood

Horizontal Laminar Flow Hood

Creates a sterile environment with minimal levels of sample contamination for small-scale, benchtop experiments. Horizontal air flow reduces the risk of user contamination and maintains smooth air flow throughout the workspace. The system includes everything you need to get started, even our smart air sensing technology.

From $3,125 ex. VAT
Vertical Laminar Flow Hood

Vertical Laminar Flow Hood

Compatible with a wide range of bulky equipment to provide a simple-to-use sterile working environment. Vertical air flow improves user protection and reduces sample cross contamination. Smart air sensing technology, UV and white light LED lighting, and IR motion detection give you complete control over your environment.

HEPA Filters for Laminar Flow Hoods and Clean Rooms

HEPA Filters for Laminar Flow Hoods and Clean Rooms

Replacement HEPA filters available in three sizes for laminar flow hoods and clean rooms. The H13 grade filters capture up to 99.99% of particulates and meet ISO Class 5 Standards for air cleanliness.

From $207 ex. VAT
Laminar Flow Hood Pre-Filters

Laminar Flow Hood Pre-Filters

Traps larger particles and prolongs the life of your high efficiency filter. Our pre-filters are rated to F5 filtration class and can filter out around 95% of particulates, with a high capture rate for larger particulates. Available in pre-cut sheets for convenient replacement, or on the roll in bulk at a discounted price.

Are Ossila Laminar Flow Hoods Sterile?


We tested the sterility of our horizontal laminar flow hoods. Our results show the workspace within the hood has significantly less contamination than the external lab environment. Working within an Ossila laminar flow hood provides:

  • A sterile workspace for up to 24 hours using both laminar air flow and UV sterilization.
  • A reduced contamination rate, compared to a regular lab when working with sensitive samples.
  • A cleaner worksurface, after sufficient disinfecting and UV lamp exposure, than a normal lab bench.
