- High Intensity UV Lamp
- Large Cleaning Area
Available From £2500
The UV Ozone Cleaner is part of the Institute of Physics award-winning Solar Cell Prototyping Platform. It provides a simple, inexpensive, and efficient method of obtaining ultra-clean surfaces free of organic contaminants. The UV Ozone Cleaner can clean a wide range of substrates, such as quartz, silicon, gold, nickel, aluminium, gallium arsenide, alumina, and glass slides.
The UV ozone cleaning process can produce an atomically clean surface in only a few minutes. However, the substrate surface must be nominally clean beforehand. The cleaning rate of UV ozone using atmospheric oxygen at ambient conditions depends on the nature of the contaminant molecules, but is typically of the order of 0.1 - 1.0 Å/s. The exact exposure times and methods required to remove various contaminants will vary and should be determined empirically.

3.7 Health and Safety - Installation
High-intensity, mercury vapour lamps can generate extreme heat and temperatures. Furthermore, ozone is a powerful oxidising agent and can react explosively with combustible materials. Keep flammable materials a minimum of three feet away from operating equipment.
The UV Ozone Cleaner is intended for operation inside a fully functioning fume hood or fume cupboard only. There is no ozone filtration system incorporated into the UV Ozone Cleaner.
3.8 Health and Safety - Operation
|UV radiation can cause severe burns to the eyes and skin. An integrated safety interlock prevents the lamp from being powered on whilst the tray is open. As a precaution, never look directly into the sample chamber when the UV ozone cleaner unit is powered on.|
|Ozone is a highly reactive substance and can cause adverse health effects at the sites of initial contact: The respiratory tract, lungs — and at higher concentrations, the eyes. The principal health effects are caused by irritation or damage to the small airways of the lungs, and symptoms include coughing and a feeling of tightness in the chest. Uncontrolled exposure to high levels of ozone could lead to more severe health effects.|
|When operating the UV Ozone Cleaner, air flow in and around the unit must remain unobstructed to prevent the unit from overheating. If the temperature inside the sample chamber reaches above 60 °C, the unit will flash a high temperature warning and automatically switch off the lamps to prevent overheating. Allow the system to cool down to room temperature before resuming use.|
|. IMPORTANT NOTE: Excessive cooling will diminish the lamp’s operating voltage and effectiveness, whereas Inadequate cooling may cause damage to system components.|
|The UV Ozone Cleaner has a high voltage source. Do not attempt to open the unit.|
3.9 Health and Safety - Servicing
Service or installation work that includes integrating electrical components should only be performed by an Ossila engineer. Never alter the wiring of any purchased equipment. If changes are made, such alterations may damage the equipment, cause injury, or even death. At the very least, such alterations will void your warranty.
If the fuses located in the fuse drawer at the back of the unit need changing, the unit must be placed in a safe mode by switching the unit off and disconnecting the power cord from the power socket.
