Slipping your children's teeth under the pillow for the tooth fairy may be a thing of the past. Now, thanks to LN2 freezer (liquid nitrogen) technology, companies are offering services to store baby teeth in case they are needed in the future to help treat or cure serious family medical issues.
The new technology allows companies to bank adult stem cells found in baby teeth and even in wisdom teeth. So instead of throwing those teeth away or having a dentist discard extracted wisdom teeth people can now store these precious dental stem cells that can be used for various dental and medical applications.
The lab harvests pulp and tissue that contains stem cells and then processes the cells for freezing. The cells are equilibrated with cyroprotectant and then placed in LN2 freezer storage units at the company. This will ensure long-term storage until the possible need by a healthcare provider.
The cost to store a tooth is just under $800 which includes the first year of storage after that fees fall about $10 a month to keep the tooth frozen.
As of right now there are no medical applications using dental stem cells but they are being used in studies. There is hope that one day – thanks to the help of LN2 freezer technology – doctors will be able to treat spinal cord injuries, MS (multiple sclerosis) and a variety of other issues.
So the next time the tooth fairy is in town, think about keeping that tooth instead of trading it in for a shiny coin. Who knows, that tooth may be worth someone's life down the road!

Use Princeton Cryo's High-Quality Cryogenic Equipment to Avoid Fines
Cryogenic freezing can certainly be dangerous. That's why we provide the best-quality cryogenic equipment possible to ensure the safety and effectiveness of all cryogenic freezing systems.
With our products you can avoid problems and fines like one large frozen pizza company who was cited for nine alleged safety and health violations. Of course, most of the fines were of a result of neglect of the company, but you can make the cryogenic freezing process easier with our products.
One of the citations was a violation of exposing workers to an oxygen deficient atmosphere.
"Employers are responsible for knowing the hazards that exist in their workplace and training workers in proper safety precautions such as air monitoring and respirator use," said Kim Stille, director of OSHA's Madison Area Office. "OSHA is committed to protecting workers, especially when employers fail to do so."
The fines totaled $76,300 after OSHA initiated an inspection of the pizza company's plant in June. The violations were issued when workers were exposed to an oxygen deficient environment during the freezing process of the pizzas in a liquid nitrogen cryogenic freezer. The cryogenic freezer created a hazardous environment due to the buildup of nitrogen gas; however, no injuries or illnesses were reported as a result of the conditions.
Other fines focused on the lack of training and implementation of safety equipment. These fines can greatly hurt any company that uses cryogenic equipment. That's why we, at Princeton Cryo, think it's important to use the best equipment in the market. We strive to create a safe environment no matter what the use of the cryogenic freezer.

The Useful But Dangerous Liquid Nitrogen
We've all heard the uses of liquid nitrogen and its unique properties that help scientists around the world discover new and amazing things. However, without the proper liquid nitrogen equipment and other precautions, the substance can quickly become very dangerous to those around the substance.
Recently, an astrophysicist in Egypt was cooling a charged coupled device camera for the observatory's telescope. He was carrying a cryogenic storage vacuum flask of liquid nitrogen which was to contain the heat coming off of the camera. The flask exploded, giving the astrophysicist severe chest and hand cold burns from the bursting liquid nitrogen.
Liquid nitrogen transfers to nitrogen gas of a rapid ration of 1:694, which is why the substance exploded. If you pour two gallons of liquid nitrogen into any warm vacuum it suddenly and immediately evaporates into a gas in front of your eyes. The properties of the substance are very dangerous for those who are unfamiliar with the safety precautions or liquid nitrogen equipment.
The gas is used for observatory and lab work but is more commonly used in refrigeration. Foods and goods can be transported around the world with the use of cryogenic storage. Liquid nitrogen is also vital in the cryopreservation of blood, reproductive cells and other biological samples.
It's also used in low temperature medical treatment in some dermatology cases. Also, construction companies may be able to use liquid nitrogen to freeze damaged water pipes and stopping water leaks during the fixing process. In the military, liquid nitrogen is used in heat-seeking missiles to prevent sensors from getting confused by their own heat signals or by the heat form the planes that are launching them.
There are so many applications of liquid nitrogen, but you need the proper liquid nitrogen equipment to ensure that the safety of everyone is preserved.

Types of biological materials that can be held in Cryogenic Storage
Cryogenic storage is very helpful when storing biological materials. Because a cryogenic freezer can freeze things at -150 degrees Celsius (refrigerated storage is about 5 degrees Celsius and typical freezer storage is about -20 degrees Celsius), it can store many biological materials without letting them go bad.
Some of the biological materials that can be stored are:
- Blood
- Plasma
- Bone
- DNA
- RNA
- Explant device storage (hips, mesh, etc.)
- Tissues and cell lines
- Agro and plant samples
- Pathology and legal specimens
- Stem cells and cord blood
- Fluids and urine
- Clinical supplies
- Serum
- Slides
This is just some of the things that can be held in cryogenic storage. The control of the temperature of valuable biological materials is very important. From storing sperm samples, blood samples to even ways of storing food, cryogenic freezing is one of the best ways to ensure pristine preservation.
Labs that have cryogenic freezers are more likely to have more beneficial biological samples and have more accurate tests for blood, DNA or other animal tissues. Thanks to cryogenic storage, biological materials can be held for a long time and won't spoil or deteriorate. This is important in guaranteeing to those who need biological specimens preserved.

Gordinier Cryogenic Tank Switcher
To work with the TEC 3000, Gordinier has developed a cryogenic tank switcher, but it only works with correct installation. If installed improperly, the cryogenic tank switcher can cause the cryogenic freezer to fire the hot gas bypass solenoid at all times when connected to the cryogenic freezer. This results in pouring liquid nitrogen onto the floor of the facility. The cryogenic freezer functions normally when the Gordineir equipment is installed properly.
In two seperate places, this tank switcher splices into the wiring of the TEC 3000. Between the controller and the 12 pin connector is the first place at the bottom of the TEC 3000. Between display panel and the RJ45 connector that plugs into the display is the second place is inside the controller. This version of Gordineir’s tank switcher only functions properly if a certified Gordinier technician installs the switcher. Chart MVE has said that the customer voids the 2 year warranty of the controller if a Gordineir switcher has been hooked up to one of Chart’s TEC 3000 units.

Cryogenic Temperature Sensor Probes
Although TEC 3000 use different temperature probes in liquid nitrogen freezers, the function is identical when compared to TEC 2000. The TEC 2000 uses only two wires and hence the temperature probe casing has a smaller diameter. On the other hand, the TEC 3000 uses three wire as a result it has a larger diameter (despite the fact that only two of those three wires are in use). They carry an accuracy of 0.12% in which both are 1000 ohm platinum RTDs. Keep in mind that the temperature with an precision of plus or minus 2°C is displayed by TEC 3000 controller.
