3M™
brand MonitorMark™ Time Temperature Indicators
Providing a visual history of time temperature exposure
MonitorMark™
Time Temperature Indicators not only signal when a threshold has
been exceeded, but provide an easy-to-read visual signal to estimate
the minimum amount of time a product has spent above the threshold
temperature.
MonitorMark™
indicators features a high contrast indicator that turns blue as
a result of exposure to rising temperatures. The indicator is irreversible,
providing a permanent record of temperature exposure even after
temperatures return to acceptable levels.
Placed
inside secondary shipper boxes of temperature-sensitive products
during shipment and storage, the indicators provide information
to assist in estimating time and temperature exposure.
 3M™
Freeze Watch™ Indicators
Providing a visual indication of freezing temperature
exposure
3M™
Freeze Watch™ Indicators are ideal for monitoring pharmaceutical
products -including vaccines, medicines and chemicals -that run
the risk of being damaged when exposed to freezing temperatures
during shipment and storage.
The
patented design of Freeze Watch indicators consists of highly sensitive
indicating liquid inside a specially designed ampule. When exposed
to freezing temperatures, the ampule fractures, releasing a liquid.
The liquid irreversibly stains a paper behind the ampule, indicating
that product has been exposed to unacceptable temperatures so product
quality testing should be performed.
Freeze
Watch indicators are available at two temperature levels, -4°C
(25° F) and 0°C (32°F), to accommodate differing product
sensitivities.
ColdMark™
Freeze Indicators
Monitor Control
With Just a Glance
ColdMark™
Freeze Indicators put you in control even after your product
has been shipped. With ColdMark, your customer know at a glance
if the product has been exposed to abusive temperatures during shipping
or storage. The ColdMark indicator accurately shows if your product
has been exposed to cold below 32°F / 0°C. (Other response
temperatures are also available.) Importantly, ColdMark is guaranteed
to work within plus or minus 1 degree of its response temperature,
the highest level of accuracy available in the industry. ColdMark
Freeze Indicators are a strategic, value-added plus for your product,
providing a permanent record that assures your customers of consistent
quality.
