How Testo is supporting critical infrastructure

The Testo Saveris data logger is used by the University of Technology
Sydney (UTS) to maintain optimal storage environments for their biological research
programmes.

As an institution offering more than 130 undergraduate and 210
postgraduate degrees in information technology, pharmacy, and biological
engineering research, UTS is required to pay attention to climate control
guidelines. The storage of pharmaceutical and biological materials isn’t as
simple as putting them in a facility closet with little-to-no air control
functions.

The World Health Organisation stipulates a number of facility climate
requirements for adherence by companies; these standards are stringent, and
define the type of temperature loggers that organisations should use.

UTS’ role in pharmaceutical, biotechnological and scientific assessments
has made indoor climate administration a priority for the institution.

University Technical Service Support Manager Philip Lawrence explains
how Testo’s Saveris data logger assists him in maintaining optimal storage
environments.

As Technical Support Manager in the Faculty of Science, Philip is
responsible for cross facility operations and projects such as the alarm systems,
field vehicle fleet, centralised glasswash, cryostorage facility and the superlab
teaching facility.

Temperature monitoring was required at the UTS facilities because their insurance
for perishable goods was contingent upon having alarms set for their temperature
monitoring system. They, therefore, rely on early detection of critical storage
problems that allow them to respond to and correct equipment failures and save their
precious samples.

The UTS facilities have multiple temperature parameters for their
samples because of their medium and long term storage requirements. Medium term
storage requires live cells to be stored below -50°C to prevent deterioration.
UTS uses a -80°C freezer for the purpose, leaving room for temperature drift
without losing cells.

For long-term storage of biological samples, UTS puts cells and nucleic
acid samples in liquid or vapour phase nitrogen as they need to be kept below
the glass transition temperature of water (below -135°C), ensuring that
molecular motion stops and all biological enzymes that might damage the samples
cease to operate.

UTS also operates incubators running different temperature set points to
cover diverse research requirements from biomedical cell culture and
cryostorage to aquatic algae and corals. Numerous biological samples are stored
at -200°C, -80°C, -20°C and 4°C temperatures.

Philip comments that the Testo Saveris temperature logger enables them
to set up new equipment on an alarm in a matter of minutes and gives them direct
control of the alarm set points as well as provides instant feedback of all
aspects of the system. This allows them to quickly test, troubleshoot and
correct problems without depending on other departments in the University.

For highly critical temperature storage, the Saveris provides rapid
alarms and also allows them to review temperature history for each incubator.
For less-critical systems, the device is used to monitor refrigerator power
supplies.

Philip concludes that the Testo Saveris temperature logger has made the
monitoring and troubleshooting of their critical storage practical and easy
even across multiple facilities that require different types of monitoring.
