|Studies have shown that fluorescent dyes commonly used to label samples are destroyed by ozone levels above 5 ppb (parts
per billion) within 10 to 30 seconds of exposure.|
It is therefore important that ozone concentration is kept below this level during sample preparation, hybridization, washing,
drying and scanning. The Cytology Ozone Free Box limits ozone to very low levels through fast and highly effective ozone destruction
(> 99%), providing an ideal workspace for every stage of microarray work which may be compromised by ozone.
Our innovative technology uses transparent PMMA to create a sealed enclosure large enough to accommodate all the relevant equipment,
a catalytic converter unit to destroy the ozone and a high precision ozone sensor to provide control and to confirm the low level of
The Cytology Ozone Free Box even keeps ozone below 5ppb with the swing up door open, allowing operators easy access to equipment
without compromising test results.
|Efficient and Fast Ozone Destruction|
|The Cytology Ozone Free Box operates by using an air circulation loop which forces the enclosure air through a highly
efficient catalytic converter, converting ozone (O3) into oxygen (O2)|
The advanced design ensures that 99% of ozone is destroyed with an airflow of just 1.5 m/s
Utilising the most powerful catalytic monolith technology produces an ozone level lower than 1ppb with the door closed and lower
than 5ppb with the door open. The catalytic filter is formulated so that it does not create any dust or powder, making the unit
ideal for use in clean rooms
Under normal atmospheric and temperature conditions, the lifetime of the catalytic filters is estimated at between 6 month to 1
|Instantaneous Monitoring of Ozone Levels|
|High-precision sensor is connected by a cable and an RJ 45 connector to the digital display||The control panel features a digital display showing ozone levels in real time.|
An alarm can be programmed via the control panel to warn users when ozone levels exceed 5 ppb.
There is an optional feature available to also show temperature and humidity levels in real time.
|Plot of ozone
concentration (ppb) versus time (min( inside the Cytology Ozone Free Box under different conditions.|
Starting from an ambient concentration of 23 ppb, ozone levels in the enclosure are reduced to less than 1 ppb in under 3 min.
Even with the door open, ozone levels usually do not exceed 5 ppb.

dust with AlphaLite ® lightweight knitted wipers constructed of 100% continuousfilament polyester. The wipers are highly
adsorbent making them ideal for spill control whilst their ultralow particulate and extractable levels make them eminently suitable
for use in cleanrooms; in fact they are supplied in Solvent-safe Bag-Within-A-Bag® cleanroom packaging.|
|Clean the far reaches of the Box with the ClipperMop which uses standard AlphaLite ® wipers.|
These are securely fastened to the head by non-abrasive polyethylene clips without releasing particles, fibres or dirt.
The mop has a flexible polyester pad for better wiping efficiency, an adjustable telescopic handle and a low profile swivel head
assembly which allows access to hard-to-reach areas.
