How to Perform a Self Audit Before a Vaccine Storage Regulatory Audit

Posted by Mike Blazes on 22 November, 2017

Vaccine storage is vital to maintaining the accuracy and efficacy of the vaccines administered today. Whether it be in a doctor’s office, medical research facility, hospital or outpatient clinic, vaccine storage requires reliable monitoring  to verify the correct temperature and environmental conditions. Vaccines can be ruined due to careless handling, and without proper monitoring could be administered ineffective. Regulatory organizations perform standard audits to examine procedures for vaccine storage. To ensure your storage methods meet required guidelines, follow these five steps.

1. Timing. Before you even begin the storage methods of vaccines, establish a schedule for ordering, whatever type of vaccines it might be. For instance, vaccinations for the flu season can begin as early as August. If you are a healthcare provider, determine when you will begin to administer the vaccine and build out a calendar from that. Vaccines have a shelf life, and their efficacy diminishes beyond it; ordering a supply of vaccines to sit on the shelf for an extended period won’t bode well.

Why Calibration is Key

Posted by Mike Blazes on 26 October, 2017

Calibration is one of those elements of lab management that is all-encompassing. Wherever there are processes monitoring temperature, testing that relies on controlled environments or storage of sensitive materials, samples or lab equipment, calibration is at the core. Why? Because it is what the ensures the validity of key instruments such as thermometers that produce the results, that maintain the integrity of samples and reliability of equipment. And, since temperature is one of the most universal and impactful parameters in a laboratory, the calibration must be done correctly and consistently. The temperature in a laboratory setting may influence:

  • Test results;
  • Effectiveness and stability;
  • Accuracy and precision;
  • Shelf-life and efficacy;

What’s The Fuss About Humidity?

Posted by Mike Blazes on 29 September, 2017

In order to understand why monitoring humidity is important, you need to understand what humidity is. Humidity is the amount of water vapor present in the air referred to as absolute humidity. Water vapor is the gaseous state of water and is invisible to the human eye. Relative humidity is how saturated a space or a gas is with water vapor. It is the most commonly used measure of humidity and is generally expressed as a percentage with the symbol “%rh.” 

When people say the humidity bothers them more than the heat, they are referring to the fact that when there is a lot of water in the air, it feels thicker and hotter and less comfortable. Relative humidity is affected by the dew point temperature which is basically a measure of how much moisture is in the air. You have probably heard meteorologist talking about the dew point in weather forecasts.

The Highs and Lows Of Barometric Pressure

Posted by Paul Atwell on 12 September, 2017

What goes up must come down? Not exactly how barometric pressure works but it is a good starting point to understanding barometric pressure and how it affects our surroundings. So what is it?  A barometer measures the air pressure in the environment. You may hear meteorologists talk about barometric pressure in their forecasts because they use it as predictor for future weather patterns. For example, low-pressure weather systems usually lead to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. * Air temperature and altitude impact barometric pressure.

High Barometric Pressure

When the barometric pressure is high, temperature conditions tend to be more comfortable as the amount of oxygen in the air is stable. As air higher in the atmosphere falls, it warms and expands. The expansion of the air in the falling air mass tends to lower its humidity, which reduces or prevents the formation of clouds. Because of this effect, areas of high pressure often have clear, dry weather.**

Low Barometric Pressure

The higher the altitude, the lower the atmospheric pressure, which means the amount of oxygen in the air decreases. That is what mountain climbers need to be careful of the altitude because it will impede their ability to breath easier due to the lack of oxygen. Low barometric pressure actually means the air pressure is rising.

Humidity Monitoring Buyer's Guide

Posted by Sarah Sameei on 21 August, 2017

Have you ever wondered why your hair becomes frizzier and curlier in humid weather? The answer to the question above is humidity. Apparently, chemical makeup of human hair is very sensitive to ambient hydrogen. So sensitive, in fact, some gadgets used to measure humidity -- called hygrometers -- rely on hair for their readings. 

So why does humidity make hair frizzy? When hydrogen bonds form between the proteins and water molecules in your hair, it will become curly and frizzy.

Cryogenically Frozen: Who's Frozen? Who's next?

A growing number of people are making the decision to be cryogenically frozen after death in order to receive a second chance at life. Despite the fact that no method of revival from being cryogenically frozen exists to this day, these individuals are hoping that advances in future medicine and technology will allow them to be revived and cured of conditions that killed them.

Looking at current research, this topic is certainly controversial both in and out of the scientific world. Many scientists claim that cryonics is founded on false promises and unprovable nonsense. Whereas others claim that death and aging will be looked upon in the future as primitive and unnecessary experiences.

 Nevertheless, reading more about the people who have already endured the deep freeze is certainly interesting and slightly bizarre.

Five Cryonically Frozen People

1. James Bedford

Bedford, a psychology professor at the University of California, is the oldest cryogenically frozen human being on earth. He died on January 12, 1967 due to kidney cancer and became the first person to enter cryonic suspension. This was a huge milestone for the cryo-community and January 12th is regarded amongst the community as “Bedford Day”.

2. Ted Williams

Williams, an American professional baseball player and member of the hall of fame, is currently the most famous cryogenically frozen person to this day. After dying of cardiac arrest, his original wishes to be cremated were overlooked as his son produced the controversial cocktail napkin on which Williams said he wanted to be preserved with his family.

5 Steps to Protect Liquid Nitrogen Dewar Contents

Posted by Mike Blazes on 05 July, 2017

 For the long-term storage of sensitive biologicals, the liquid nitrogen dewar is a system that provides the optimal environment of a stable, low-temperature necessary to maintain the life of delicate cells. The dewar is a non-pressurized vessel that is specifically designed and made of materials that have the ability to withstand the extreme temperatures associated with liquid nitrogen. Liquid nitrogen is odorless, colorless, tasteless, and nonirritating; therefore, it has no warning properties and must be carefully handled. With a boiling point at a low temperature of -196˚C, liquid nitrogen is considered a cryogenic liquid and can be used to store organisms with limited life spans.

 With cryopreservation being possible due to liquid nitrogen, medical procedures and research can be further advanced with biologicals like stem cells, tissues, and other samples being kept alive forever in liquid nitrogen dewars.

Here are five steps to protect your liquid nitrogen dewar and its contents:

  1. Use a reliable temperature monitoring system. In order to stop any biochemical reactions that could result in cellular degradation, most sensitive biologicals should be maintained at very low temperatures within the dewar. Lower storage temperatures such as -196˚C enable organisms with limited life spans to remain alive forever. The most effective method to guarantee the safety and consistently low temperature of the dewar’s contents is to implement a dependable liquid nitrogen temperature monitoring system.
  2. Always Keep the dewar upright. The dewar should remain in an  upright position at all times to ensure safe storage. Tipping the dewar over or laying it on its side could result in spillage of liquid nitrogen. Damage to the dewar or to any materials stored within could occur as well.

LN2 Dewars: Covering Your Cryo-needs

Posted by Mike Blazes on 27 June, 2017

Dewars and Cryopreservation

Liquid nitrogen is a unique substance that can be both harmful and helpful to mankind. As a liquid that exists at a very low temperature of -196˚C, liquid nitrogen has the ability to freeze human flesh rapidly. Despite the dangers of frostbite, over-pressurization, and asphyxiation, liquid nitrogen can be used for various other needs such as medical procedures, food preparation, and cryogenics. Liquid nitrogen can be stored in a dewar, a non-pressurized vacuum container that can maintain a consistent temperature allowing the nitrogen to remain in liquid form. Dewars range in capacities from 3 to 300 liters.

When liquid nitrogen is placed within a suitable dewar, the process of cryopreservation is possible. Cryopreservation allows for the preservation of biological constructs at very low temperatures used to form cryogenic liquids. At such low temperatures, any chemical activity that might cause damage to delicate biologicals is halted. Reaching low temperatures without the formation of ice halts any additional damage to the living organism, allowing the organism to live forever and be used as needed.

The Importance of Properly Storing and Handling Vaccines

Posted by Sarah Sameei on 07 June, 2017

Measles. Mumps. Smallpox. Polio. Diphtheria. Tetanus. Yellow Fever. Influenza. Hepatitis.

Imagine a world where all children of the present day commonly suffered from these diseases. The vast majority of them would be blind, deaf, or unable to live independent lives due to various disabilities resulting from these and other diseases. Great care would have to be taken in this hypothetical world to not get sick. And still that probably would not be enough to prevent illness.

The world would look vastly different.

Thankfully, these eliminated diseases are no longer a major concern in an ever-increasing share of our present world thanks to one of the most important inventions of all time: the vaccine.

People rely on vaccines to ensure that they will not have to endure many diseases or resulting disabilities in their lifetime. A bothersome scenario is a population that thinks it is receiving immunization, but is left further vulnerable to diseases. This is what happens when a population thinks it is being safe and a vaccine, that could have been either improperly stored or mishandled, is no longer effective.

Properly Storing Vaccines
Technology has had a huge impact on the effectiveness of vaccines. Thermometers have especially undergone the shift from consumer technology, simple digital home devices, to healthcare technology, information technologies used to enhance and optimize processes and improve care.
