Selecting Scientific Refrigeration Equipment

Scientific refrigeration equipment includes refrigerators and freezers used to store vaccines, pharmaceuticals, biological samples and similar temperature-sensitive products and specimens for healthcare, R&D and related applications.  Scientific refrigerators and freezers have critical performance requirements generally unmet by residential and commercial refrigeration systems.  For this reason they are highly recommended to protect contents that lose potency or are otherwise compromised by what are called temperature excursions above or below recommended storage settings. Therefore, selecting scientific refrigeration equipment for your needs is key.

Correct storage temperatures are usually recommended by professional or government organizations.  The CDC, for example, recommends in its 2016 Vaccine Storage and Handling Toolkit that frozen vaccines be stored between -50⁰ and -15⁰C (-58⁰ and + 5⁰F); refrigerated vaccines should be stored at 2⁰ and 8⁰C (36⁰ and 46⁰ F).  Vaccine manufacturers indicate correct storage temperatures that should apply along what is called the “cold chain” extending from the … Read the rest

Vaccine Refrigeration - 10 Essential Items to Consider

Proper vaccine refrigeration is not a hit-or-miss proposition.  Each year there are reports on how improper vaccine storage or other mishaps relating to vaccines result in loss of potency.  This necessitates locating and revaccinating those who have received compromised inoculations plus the associated cost and inconvenience.  Proper vaccine storage is also a critical element for complying with government-funded Vaccines for Children (VFC) programs.

Vaccine manufacturers are careful to note the proper storage temperatures for their products along what is called the cold chain of custody between manufacturing and inoculation.  But manufacturers have little influence on the equipment used by healthcare facilities to maintain these temperatures.  The CDC (Centers for Disease Control and Prevention) has stepped into this by issuing its 2016 Vaccine Storage and Handling Toolkit to provide comprehensive information on this vital activity.    The Toolkit also covers in detail the importance of staff training and written standard operating procedures … Read the rest

How to Comply with CDC Vaccine Storage Temperature Monitoring

Digital data logger for vaccine storage

Digital data logger for vaccine storage

One of the recommendations found in the CDC’s Vaccine Storage and Handling Toolkit is the use of digital data loggers along with audio and visual alarms to log internal storage temperatures and sound alarms if temperatures fall outside set limits.  Vaccine storage units that otherwise comply with CDC’s high/low temperature alarm recommendations may not be equipped with the all-important ability to record temperature history.  Instead they rely on personnel manually recording internal temperatures twice daily*.

Temperature Chart Recorders

Automating temperature monitoring can be achieved with the use of temperature chart recorders.  These are attached by wire to temperature sensors placed in glycerin or glycol-filled bottles positioned in the refrigerator or freezer.  The liquid “insulates” the sensor from spikes that occur when the unit’s door is opened to place or retrieve vaccines and other pharmaceuticals or samples. A disadvantage of … Read the rest
