Cytology Ozone Free Box
 
Continuous protection from ozone throughout preparation, hybridization, washing, drying and scanning
 
Cytology Ozone Free Box
 
Features
  • Protects fluorochrome dyes from ozone degradation
  • Provides continuous protection for every step of microarray work
  • Swing up door for ease of access to all microarray equipment
  • Automatic air curtain protects box contents when door open
  • Ozone level below critical 5ppb even with door open
  • Ozone stabilised at 1ppb when door closed
  • 2 programmable ozone alarms can be set to warn if levels are rising and if critical 5ppb level has been breached
  • Airflow of 1.5m/s can be boosted to cope with rising ozone levels caused by outside pollution or by equipment in the box
  • Available in 2 standard sizes to cover virtually every microarray platform configuration
  • Optimised to house scanner, hybridisation station, mini centrifuge, hybridisation cassettes, wash stations and hotplates in a single protected enclosure
 
Applications
Analysis of:
  • DNA

Description
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 ozone achieved.

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 year

Instantaneous Monitoring of Ozone Levels
 
Cytology Ozone Free BoxCytology Ozone Free Box
 
High-precision sensor is connected by a cable and an RJ 45 connector to the digital displayThe 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.
 
Results
 
Cytology Ozone Free BoxPlot 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.
