Price to be confirmed

Vertical and horizontal laminar flow hood for perfect clean air

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


The Ossila Laminar Flow Hood has been designed from the ground up to provide the simplest experience for working in clean and sterile environments. Behind the design of the system is the need to ensure consistently clean air, free of dust and microbial contaminants. To do this we have developed our new smart air sensing technology that monitors the current particulate count within the air stream of the laminar flow hood. Using pressure, temperature, humidity, and particle count data the smart air sensing software controls the rate of air exchanges within the hood to ensure that the air that is present is always clean.

The smart air sensing technology can also ensure that the motor operates only at the speed that is needed to provide clean laminar air. This allows the system to use much less power while maintaining the same air quality, reduces the noise of the system, reduces the number of filter changes required, and keeps energy usage to a minimum. Additionally, the laminar flow hood comes equipped with state of the art UV and white light LED lighting for further reduction in power consumption, along with IR motion detection to enter the system into power saving modes when not in use. This means that the Ossila Laminar Flow Hood not only keeps the air you are working in clean it also minimises operational costs, and helps to reduce overall carbon emissions.

Unlike other laminar flow hoods, the Ossila system comes fully equipped with filters, sensors, control electronics, and tray. With fixed rate worldwide shipping, our free two-year warranty, and free online support, the Ossila Laminar Flow Hood is the best choice for your research.

What is a Laminar Flow Hood?


Laminar flow hoods are dedicated spaces which are used to provide an environment to work in where the presence of air borne contaminants are significantly reduced. This is of importance for areas of research such as semiconductor fabrication, thin film electronics, medicine, microbiology, or any other 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 filter (HEPA filter). Contaminants present in the air are captured within the fibres of the filter and the air that is expelled is free from air borne particles. The laminar flow hood gets its name from the fact that the air expelled from the filter is at a low velocity and retains a laminar profile across the length of the cabinet.

The laminar flow present within the hood provides additional contamination control. The first way it does this is that it flushes out contaminants present within the hood when first turned on. Secondly, it also ensures that no air from outside the hood encroaches inside by eliminating the presence of vortices that could cycle outside air into the hood carrying particulates within it.

Greener Science

Greener Science

The incorporation of smart air sensing software allows the Ossila Laminar Flow Hood to reduce power consumption compared to a standard laminar flow hood. Reduced motor speeds are not the only power saving feature implemented in this product. Our filter saturation monitor can tell you when to change filters, reducing strain on the motor; the white light and UV LED's allow for low power high efficiency lighting; our motion sensors allow the system to enter a low power mode while not in use. All of these features work together to ensure that power is not wasted.

With the particle filtration offered by the Ossila Laminar Flow Hood, the system can achieve air cleanliness values as low as ISO Class 3. The smart air sensing technology provides constant monitoring of particulate count within the laminar flow providing instant feedback on the current ISO classification of the air you are working within.

What is Laminar Air Flow Used For?

Access to environments where the air is free of both physical particulate contaminants as well as microbial contaminants is essential in many areas of research and manufacturing. The presence of either particulates or microbes, even in minute quantities, can have a dramatic impact on the the data produced in research or the yield in a manufacturing process. Undertaking work within a clean environment free from any potential source of contamination is therefore essential. Laminar flow hoods are an essential tool in clean environment working. They provide a workspace in which clean air is constantly passed over the area you are working within. This air is at an elevated pressure compared to the air outside the hood ensuring that contaminated air from outside the work space is unable to re-enter the hood protecting what you are working on. In addition, laminar flow hoods are designed to ensure that the air present within the hood retains laminar characteristics. This means that the air present is not turbulent and does not form vortexes which could cause pockets of stagnant air for contaminants to form, or allow for recirculation of contaminated air back into the hood.

Thin Film Electronics

Modern thin film electronic devices are a huge field in research and manufacturing. A variety of electronic devices can be fabricated using thin films of materials stacked on top of each other. With each layer typically only being tens of nanometres thick. This allows researchers to observe unique properties of the materials that are only present in these constrained dimensions.

Processing of such devices in a clean environment is critical to achieving high performances and for obtaining high yields within manufacturing. The presence of airborne contaminants that could settle onto the surface of these devices often result in complete device failure as they are orders of magnitude larger than the device themselves.

The Ossila Laminar Flow Hood with its high capture efficiency HEPA and ULPA filters can ensure minimal airborne particulates are present in your working environment. Giving you the tools you need to push device performance even further.

Microbiology Research

Sterility of equipment and the environment is fundamental in undertaking any form of microbiological research. Everything from the initial preparation of growth media and plates, to the incubation environment are periods in which contamination could occur. Ensuring any environment in which you expose your sample, or work within, is sterile is key to making sure your samples are protected.

The Ossila Laminar Flow Hood with its smart air sensing technology can monitor the amount of airborne particulates present within the laminar flow hood. Giving you an instant readout of the air quality. Allowing you to have the peace of mind that the environment you are working it will not introduce unwanted contamination into your work.

Wafer Fabrication

Wafer fabrication involves the production of precise circuitry on the surface of semiconducting wafers. These circuits can be as small as tens of nanometers in size. To achieve such small features a range of processing techniques are used to pattern the surface. This patterning process is extremely sensitive to the presence of any particulate contamination.

With ULPA filtration the Ossila laminar flow hood can provide you with an environemnt where the air cleanliness is as low as ISO Class 3. Giving you air with extremely low particle counts allowing you to undertake steps of wafer fabrication, assembly, and encapsulation.

Medical Research

The production of pharmaceuticals is mostly handled via batch production via highly specified formulations. However for certain paitents due to highly specific needs sometimes medication must be tailored. Similarly in research the small scale production of pharamecuticals and the unoptimised dosages often means tailored batches are required. In these circumstances pharmaceutical compounding procedures should be followed to ensure no contamination occurs.

Laminar flow is essential for ensuring no contamination of the work area and the samples. The Ossila Laminar Flow Hood provides clean air up to ISO class 3 ensuring minimum primary engineering controls for handling. In addition, the optimised hood and plenum structure ensure laminar unidirectional air flow across the hood. And with our advanced air collimating filters unidirectional flow can be maintained over longer distances and recovers faster upon disturbance.

Manufacturing

For the final assembly of electro-optical, opto-mechanical, and general photonics parts the use of a cleanroom environment is important. Often, these components use sealed systems where the combined properties of the optical, mechanical, and electronic components. Once sealed these parts are protected from external environments, however what is sealed within remains. Assembling the components together within a cleanroom environment ensures that no particulate materials are trapped within once sealed.

Ossilas Laminar Flow hood provides a clean work area that can be easily used for the assembly. Ensuring that no dust contaminants can impact upon your final assembly once finised. With variable cleanroom classification control you can create the environment you need for each process, keeping your costs to a minimum.
