Horizontal Laminar Flow Hood for Bench Top Experiments

Fully equipped with advanced sensor technology, full set of filters, stainless steel tray, and UV lighting

The Ossila Horizontal Laminar Flow Hood has been meticulously crafted to provide a sterile environment where you can conduct your experiments easily and reliably. The benchtop design and horizontal laminar air flow diminish the risk of contamination and are suitable for a wide range of experiments. It is the perfect choice if you are conducting bench top or small-scale experiments.

Standing apart from other systems, laminar flow hoods from Ossila arrive complete with compatible HEPA filters, sensors, control systems, and tray. Easily assembled on site, the Ossila Horizontal Laminar Flow Hood benefits from worldwide shipping and our free two-year warranty.

Equipped with advanced environmental sensors and innovative software, laminar flow hoods seamlessly track temperature, pressure, and particle concentrations within the workspace. Continuous monitoring provides live insights into the conditions within the hood, while ensuring the motor runs at peak efficiency. This results in a decrease in energy use, a quieter workspace, and extended filter life. When paired with the eco-friendly lighting and energy saving modes, our horizontal laminar flow hood cuts down on operational costs and is more environmentally conscious.

In the horizontal configuration, the filter is positioned at the back of the hood and air flows parallel to the work bench. Any contaminants which enter the hood are swiftly removed through the front panel, with minimal disturbance to samples on the bench.

The Ossila Horizontal Laminar Flow Hood comes flat-packed and is also configurable as a vertical laminar flow hood depending on your preference and requirements

What is a Horizontal Laminar Flow Hood?

Laminar flow hoods are dedicated spaces with significantly fewer airborne contaminants. This is important in many areas of research, including:

  • Semiconductor fabrication
  • Thin film electronics
  • Medicine
  • Microbiology
  • Any research where the presence of external particles on the samples are unwanted

Laminar flow hoods work by filtering air through a high-efficiency particulate air (HEPA) filter, which captures any particle contamination. All air that enters the flow hood is therefore free from dust or other particles. In a horizontal laminar flow hood, this filter is placed at the back of the cabinet. Filtered air is expelled directly towards the outside environment, effectively removing contaminants.

Why Choose a Horizontal Laminar Flow Hood?

Significant Protection from Contamination

Horizontal laminar flow hoods offer a high level of protection against sample contamination. Air flows parallel to the work bench, continuously removing dust and other particles from the hood. This minimizes the risk of your samples being compromised by unwanted particles in your workspace, such as dust on gloves or stray materials.

Reduced Risk of User Contamination

Placing your hands into a horizontal laminar flow hood does not interrupt the laminar flow. Dust and impurities on your hands or gloves are quickly pushed out of the workspace. User contamination is greatly reduced as a result, when using the horizontal configuration.

Smooth Air Flow at Bench

Horizontal air flow is less likely to create turbulence near the work bench, unlike air flow in the vertical laminar flow hood. If you are consistently working on the bench top, the horizontal configuration will protect your samples effectively without disturbing them. When making media plates or working with small-area thin film samples, you may therefore require a horizontal laminar flow hood.

Low Operating Costs

With smart air sense technology, the Ossila Horizontal Laminar Flow Hood offers enhanced efficiency and reduced energy expenses. While actively reviewing the air purity in the hood, the system will alert you to its current state and the degree of HEPA filter saturation.

Beyond this technology, the hood boasts a range of energy-saving features. These include low-energy lighting, infrared motion sensors that activate standby mode, UV LED with adjustable timers, and back pressure sensors to track filter saturation. Collectively, these features ensure minimal power consumption.

Laminar Flow Hood Sensors

Smart Sensor Technology

The Ossila Horizontal Laminar Flow Hood integrates an array of environmental sensors. The system offers pressure and temperature readings, passive infrared motion detection, and laser scattering for airborne particle counting. Collaborating with our advanced smart air sensing technology, these sensors preserve consistent, superior air quality within the hood.

Continuous air quality management not only ensures compliance with stringent ISO standards, but also actively tracks filter saturation. This alerts you to upcoming HEPA filter replacements, streamlining system maintenance.
