How to Choose a Blood Bank Refrigerator

Calls for blood donors often intensify after local or regional disasters as public safety responders and healthcare facilities seek additional supplies from local blood banks.   A blood bank refrigerator performs an important function in maintaining the safety of blood according to regulations by the Food and Drug Administration’s (FDA) Center for Biologics Evaluation and Research (CBER).  Other standards organizations include the American Association of Blood Banks (ABBA) and the American Red Cross.

Section (h) of the FDA’s 21CFR640.4 relates to the storage of blood immediately following collection.  It states that unless the blood is to be used for platelets it should be placed in storage at temperatures of 1 to 6˚C (39 to 43˚F).

Primer on Laboratory Refrigerator & Equipment Validation

A controlled environment is critical to maintaining the potency and safety of pharmaceutical products across a supply chain stretching between R&D laboratories, manufacturing facilities, transportation and storage at healthcare facilities.  Examples of controlled environments include laboratory refrigerators, laboratory freezers, blood bank refrigerators, chromatography refrigerators, laboratory incubators, stability chambers and temperature test chambers.

Equipment such as this as manufactured by Norlake Scientific and offered by Tovatech is designed and constructed to comply with standards developed and promulgated by the FDA, the AABB, the Red Cross and other agencies.  Once the equipment is purchased, however, the facility operator assumes the responsibility of assuring it is installed and maintained according to FDA and related guidelines.… Read the rest

How to Choose a Laboratory Incubator

Laboratory incubators used in microbiology laboratories and other research and development applications provide an environment for growing cultures under controlled conditions such as humidity, temperature, and CO2.   Several regulations apply to operating a laboratory incubator so it is important to be certain that the laboratory equipment you buy is designed to meet your particular requirements.

Experts suggest that even before purchasing a laboratory incubator you should first consider what it will be used for and where it will be located.  So instead of buying an incubator and then trying to make it fit your process or needs, turn the procedure around.  This makes sense not only for assuring proper performance; it helps you pick a model that is most cost-effective for your needs.… Read the rest
