Use Lab Refrigerators and Lab Freezers to Avoid Vaccine Spoilage

Correct storage is vital to protecting vaccine potency.

According to recent reports, of the billions of dollars of vaccines shipped annually to healthcare providers, tens of millions of dollars worth are lost due to improper storage.  These substantial losses occur because of a failure to maintain the critical “cold chain” that originates at the point of manufacture and ends just prior to vaccine administration by healthcare providers.  Laboratory refrigerators and laboratory freezers are vital links in the cold chain.

Correct Refrigeration is Crucial

Vaccine manufacturers provide explicit instructions on correct storage temperatures – either refrigeration or freezing – essential to safeguard the potency of their products.  It is the responsibility of healthcare provider organizations – from clinics to hospitals – to ensure these temperatures are maintained.  Laboratory refrigerators and laboratory freezers are the answer.   Equipment such as the microprocessor-controlled Nor-Lake Premier line scientific refrigerators and scientific freezers available from Tovatech are especially designed for vaccine storage.  Refrigerators can … Read the rest

Forensic Refrigerator has Lockable Compartments

9-compartment forensic storage refrigerator

9-compartment forensic storage refrigerator

Health practitioners, law enforcement agencies, defense and prosecuting attorneys know the value of properly handled and preserved forensic evidence to identify victims and suspects and to help build cases leading to verdicts by jurors.  Procedures for the proper storage of these samples have been established, and proper refrigeration is a key element in many of these procedures.

Evidence such as blood and tissue samples that require refrigeration can be safely stored in a forensic laboratory refrigerator now available from Tovatech. It has 6 compartments 8-1/4”h x 9”w x 13”d, 2 at 11”h x 9”w x 7”d and one at 8-14”h x 9”w x 13”d.  Each compartment has its own combination lock to help protect against unauthorized access.  Totaling 10 cubic feet of storage space the 56-inch high forensic evidence refrigerator has a 2-foot square footprint and additional storage shelves in the reversible door.… Read the rest

How to Use Your Lab Refrigerator for Proper Flu Vaccine Storage

With the 2010-2011 flu season upon us the Centers for Disease Control and Prevention (CDC) recommends a flu vaccine as the first and most important step in protection.  But protecting the vaccines against degradation is also important and is accomplished by proper storage in vaccine refrigerators. Through the Advisory Commission on Immunization Practices (ACIP) the CDC recommends that the flu vaccine is stored at 35°F to 46°F and should not be frozen.  If the vaccine is frozen it should be discarded.

The selection of a vaccine refrigerator should not be taken lightly by healthcare facilities that store and administer flu vaccine. Residential refrigerators generally do not possess the control and monitoring features available in Norlake Premier auto-defrost laboratory refrigerators available from Tovatech.  These units feature a digital LED display microprocessor temperature controller that can be set between 35.6°F and 50°F.  Vaccine protection is further assured by an audible and … Read the rest

Protect your Investment in Lab Refrigerators and Lab Freezers

Scientific lab refrigerators and lab freezers are substantial investments necessary to insure compliance with storage regulations for pharmaceuticals, vaccines, enzymes, blood, plasma, cultures and similar products.  If these units malfunction due to improper operation and maintenance, your organization is not only subject to being cited for non-compliance by the FDA and/or other regulatory authorities but also the financial loss of the contents in the lab refrigerator or lab freezer.

While lab refrigerator and lab freezer manufacturers such as Norlake Scientific provide detailed instructions on the proper setup and use of these units, operating procedures should be detailed in your company’s operations manual to govern their use and maintenance during their service life.  As one example, floor plan reconfigurations in your lab or manufacturing facility may change, resulting in the lab refrigerator or lab freezer being moved.   Wherever they are relocated, care must be taken to insure the move is … Read the rest

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

Laboratory Refrigerators: Automatic or Manual Defrost?

Cold-storage solutions for costly laboratory samples are not found at a local appliance store, but instead are the result of careful purchasing decisions based on the value of the products being stored. The price of poor laboratory refrigeration was dramatically demonstrated in a December 4, 2007, USA Today article reporting that it accounts for a big part of the $20 million in waste incurred by the federal Vaccines for Children program.… Read the rest
