OZONE FREE BOX
 |
The Ozone Free Box™ has been specially
designed to prevent the destruction
of Cyanine 5 by ozone. Cy5 destruction has been
reported after 10-30 seconds exposure to ozone levels
above 5-10 ppb*, especially during array washing, drying,
and scanning.
(* ppb: parts per billion).
|
Ozone effects on microarray data quality:
• Strong reduction of spot intensities (degradation
of the Cy5)
• Reduction of Cy5/Cy3 ratio
• Erroneous analysis
• Impact on the budget for microarrays
The Ozone Free Box™ destroys ozone during the
hybridization, washing, drying and scanning steps.
With our innovative technology using a catalyst filter,
we guarantee a level of ozone lower than 1ppb with the
door closed and lower than 5ppb with the door open. The
objective of anti-ozone treatment is to achieve a concentration
lower than 5ppb to achieve the best possible signal intensities.
Ozone Free Box™ is composed of a transparent PMMA
box, a catalyst filter unit and a high precision ozone
detector. |

fig.1: Catalyst Filter
The filter is made of aluminium with deposit of manganese
oxide (MnO2 ).
Manganese oxide is the chemical compound MnO2, commonly
called manganese dioxide. The black filter is used as
a catalyst. Our design (fig.1) significantly increases
the destruction of ozone (> 99%) with an airflow of
only 1.5 m/s. |
 |
 |
The tests on the side have been made in
parallel using identical protocols.
Microarray 1 was hybridized and scanned in ambient laboratory
air (Fig. 2), while the other was processed in an environment
without ozone (Fig. 3).

fig.4: The Ozone Free
Box™ is equiped with a high-precision sensor with
a high resolution (±1 ppb) fixed inside the box
and connected by a cable and an RJ 45 connector to a
digital display located in front of the filter catalyst
unit.
fig 5: The control panel is equiped
with a digital display which indicates the level of
ozone in real time.
An alarm can be programmed via the control panel to
notify users when ozone levels are in excess of 5 ppb.
