According to the AABB, whole blood should be stored between 1⁰ and 6⁰C.  Storing blood at the correct temperature in a small medical or healthcare clinic blood bank is facilitated with a new 4.2 cubic foot undercounter glass door blood bank refrigerator available from Tovatech.  Safe storage is enhanced with the unit’s digital LED display microprocessor temperature control range from 2⁰ to 8⁰C, an audible and visual hi/lo temperature alarm and remote alarm contacts.  The lock and magnetic gasket-equipped self-closing glass door allows healthcare providers to check contents without opening the door, which admits ambient air.

The Nor-Lake NSBR041WMG/0 undercounter blood bank refrigerator features a continuous content temperature display and is shipped with a free-standing temperature chart recorder and chart paper.  The sensor access port also allows fitting of auxiliary monitoring and alarming devices as described in our post on alarming system options.

The four sliding drawers in the auto-defrost refrigerator for blood banks have a combined storage capacity of 88 blood bags.  The aluminum interior is easily cleaned and the base mounted forced air front breathing refrigeration system allows the cabinet to be enclosed on two sides.  Its air cooled condensing unit is equipped with a filter screen, also for easy maintenance.

Blood Bank Refrigerator Temperature Settings

A recent post by Williams Laboratories looked at the importance of the temperature set on blood bank refrigerators.  It noted that most equipment offered provides a temperature range of 2⁰ to 8⁰C and a factory set temperature of 4⁰C – as does the Norlake undercounter model.

But an important consideration is how long it takes blood in a blood bank refrigerator to warm to the upper limit when the blood bag is transported and dispensed.  A graph provided with the post shows that the time it takes blood to reach the upper 6⁰C limit when stored at 4⁰C is approximately 3 minutes.  Compared to this relatively short time limit, if blood is stored at 2⁰C the transport time to reach the 6⁰C limit is approximately 7.5 minutes.

While this makes a strong case for storing blood at the lower temperature there is a reason why the industry standard is 4⁰C.   The typical temperature uniformity in these refrigerators is ±1⁰C.  This means that if the thermostat is set to 2⁰C with ±1⁰C uniformity the inside temperature might reach the lower limit of the acceptable range or 1⁰C.  Setting the thermostat at 2⁰C and the low alarm to 1.5⁰C may also cause the alarm to go off at 2⁰C.

About Rachel Kohn

So how did an MIT Ph.D. end up selling refrigerators? When I figured out that a lot more scientists buy lab refrigerators than innovative leading-edge instruments. I hope that my many years of lab experience will help you find the right equipment for your work. Before co-founding Tovatech I worked in business development and project management at Smiths Detection, Photon-X, Cardinal Health, and Hoechst Celanese. And before that I spent 12 years as an R&D chemist at Hoechst Celanese and Aventis working on advanced drug delivery systems, polymer films and membranes, optical disks, and polysaccharides. Some day, eventually, I’ll make enough money to develop an innovative technology that will change the world. Read More
