Vaccine protects us.

SAVE OUR VACCINES
According to the World Health Organization (WHO), there is over 50% vaccine wastage globally every year, in part because some points of vaccination, such as healthcare providers in poor or rural areas, may not have the resources to support cold chain requirements. Today, most of the vaccines developed in the west are messenger RNA (mRNA) vaccines. They are particularly vulnerable to degradation by enzymes and must be stored and shipped in subzero to even ultra cold environment. It thus poses a great challenge onto the cold chain of vaccine from transport, storage, continuous temperature monitoring to the last mile delivery before final administration.
Dry Ice is not the only choice. BocaPCM is a better alternative.
Some vaccines are based on a novel approach that targets the virus using synthetic mRNA to mount an immune response. mRNA tends to be more fragile, which requires storage and shipping at a very low temperature to maintain the vaccine’s stability. Although dry ice shares a fair part of cons, in some parts of this cold chain Dry Ice is the only choice, but not anymore when BocaPCM comes to the stage.
Dry Ice vs BocaPCM
| Compare Item | Dry Ice | BocaPCM |
|---|---|---|
Danger (Explosiveness) | When sublimating into gas, dry ice will blow off an airtight container. | Safe. BocaPCM is free of the danger of explosion. |
Storage | Dry ice will melt into gas even placed inside a freezer. Require special storage with ventilation and timely use. | PCM sheet or panel can be placed anywhere without undermining chemical nature and usage. |
Working
Temperature | For cool only (below zero degree Celsius) | Also for cold-to-cool (Above zero degree Celsius). A wide array of working temperature available, from cold to extremely cool. |
Disposal | Consumable. Need special treatment for leftover. | Reusable for years. |
Contamination | Cannot use for Seafood or flower, etc. | No contamination. |
Portablity | Not portable | Portable |
Challenges in Vaccine Cold Chain
Boca PCM COLD CHAIN
Temperature-controlled Storage Solution
To end the Covid-19 pandemic many kinds of vaccine have been developed and become available to the public. However, there are great challenges posed by the specific cold storage and logistics requirements for these precious but extremely vulnerable gems. With our unique and leading thermal storage technology powered by Phase Change Material (PCM), Boca developed the BocaPCM Temperature-controlled Storage Technology which provide an ultra-cold solution to help and support the world in its mission to get past this pandemic. We have prepared technically and materially for the cold chain challenge and honorable to introduce our Ultracold Series PCM that reaches as low as -86℃. Besides this achievement, we have also prepared specific PCM for preserving a temperature level of -50℃.
We have developed a series of PCM for different temperatures at ultra-cold level. Take a look at one of our experiment for -50 ℃ level:
PCM Cold Chain Application
Utracold Storage Container
Application 2: Boca PE-50 Panel
NEW! Maintain the ambient temperature of a freezer at -50℃ ~ -40℃ for 24 hours for power outage. Recover to optimal storage temperature very soon, PE-50 is an economical option for cooling redundancy to help ensure the safe, secure and reliable long-term storage of your priceless and irreplaceable biological samples, vaccines or lab contents.
Simply freeze the PE-50 panels 2 to 3 days inside your cold storage cabinet beforehand, you no longer have to worry about risking your biological samples like DNA, RNA, proteins, cell extracts, or reagents for thawing damage at a sudden power outage.
Recover to optimal and stable ambient temperature very soon. Ensure the viability of your precious samples. Optional temperature mapping device is available for real-time monitoring and gauging of temperature data in the emergent event of power outage or malfunction of cooling system.
Features：
*In the event of power outage/malfunction of cooling system, maintain cabinet temperature at -50℃~-40℃ for 24 hours.
*Working for various temp control configurations, just equip appropriate quantity of PE-50 panels.
*Chemicals stable. Panels durable and reusable for 5 years.
Here is the temperature curve of a 780L Stirling SU780XLE refrigerator:
*Discrepancy may be observed among the data gathered from different brands of refrigerator. Just apply appropriate quantity of Boca PE-50 panels as per kinds of cold storage configuration and various temperature demands.
*Fitted with optional temperature recorder which maps temperature curve under any emergency circumstances.
The Mechanism behind ULT Preservation：
When temperature starts to rise due to power outage, the Boca Phase Change Materials inside the PE-50 Panels will absorb a great deal amount of latent heat during the phase change from solid to liquid state. This process helps preserve the Ultra-Low Temperature (ULT) storage environment for vulnerable samples and prevent accidental thawing damage.
| Items | Parameters |
|---|---|
Model | PE-50 |
Pull down Temp & Time | Place PE-50 panels inside an ULT freezer and wait for 2-3 days for a stable -70℃/-80℃ ambient environment. |
Temp Preservation Duration | Place enough PE-panels inside an ULT Temp freezer. After their temperature pulled down, the cabinet can be preserved at a stable -50℃ to -40℃ for 24 hours in the event of power outage or malfunction of cooling system. |
Is PE-50 panel reusable? | Yes, good for 5 years except human damage. |
