Supporting Pharmaceutical Shipping with Dry Ice

Pharmaceutical products can travel hundreds or thousands of miles between the place where they are manufactured and the place where they are ultimately used. Throughout that journey, some products must remain within tightly controlled temperature conditions.

That makes shipping part of the product-handling process.

Vaccines, biological samples, temperature-sensitive medications, and other pharmaceutical products can be affected when proper conditions are not maintained during transportation. A package may only be in transit for a day or two, but those hours matter when the contents depend on temperature stability.

Dry ice provides a practical cooling solution for pharmaceutical shipments that require very low temperatures. Its ability to maintain extreme cold without electrical refrigeration has made it an important part of cold-chain logistics throughout healthcare, pharmaceutical, biotechnology, and research operations.

Why Dry Ice Works for Temperature-Sensitive Shipments

Dry ice is solid carbon dioxide with a surface temperature of approximately -109.3°F (-78.5°C). Instead of melting into liquid as it warms, it sublimates directly into carbon dioxide gas.

That property gives dry ice an important advantage in shipping. It provides intense cooling without introducing liquid water into the package.

For pharmaceuticals, vaccines, biological samples, and other sensitive materials, avoiding excess moisture can be valuable. nexAir specifically notes that dry ice’s sublimation can help eliminate the risk of contaminated meltwater coming into contact with sensitive pharmaceutical products.

Dry ice also works without electrical power, allowing appropriately designed shipping containers to maintain cold conditions while packages move between facilities.

Temperature Control Protects Valuable Products

Pharmaceutical products can represent a significant investment long before they enter a shipping container. Research, manufacturing, testing, quality control, and distribution all contribute to the value of the final product.

A temperature problem during transportation can put that work at risk.

Cold-chain planning is therefore about protecting both product integrity and the investment behind it. The required conditions depend on the specific product, and shipping procedures should always be based on the manufacturer’s handling and temperature requirements.

Where dry ice is appropriate, maintaining an adequate quantity throughout the expected transportation period helps support stable low-temperature conditions.

The cooling strategy needs to account for transit time, packaging, environmental conditions, and possible delays rather than assuming every shipment will follow the ideal schedule.

Dry Ice Supports Pharmaceutical and Biotechnology Research

Dry ice is important before pharmaceutical products ever reach commercial distribution.

Research laboratories use it to preserve biological samples and temperature-sensitive materials. Biotechnology and pharmaceutical operations may need to move research materials between laboratories, testing facilities, clinical sites, and other locations while maintaining low temperatures.

A compromised research sample can represent weeks or months of work.

Reliable dry ice supply therefore supports both pharmaceutical shipping and the larger research process behind pharmaceutical development.

nexAir’s dry ice solutions serve healthcare clinics, research facilities, and other life science applications where temperature control matters.

Shipping Plans Need to Account for Sublimation

Dry ice does not remain solid forever.

Because it sublimates continuously, pharmaceutical shippers need to account for how much dry ice will remain throughout the expected transit period.

That means the amount packed at the beginning of a shipment should be based on the packaging system, required temperature, travel time, environmental conditions, and other relevant factors.

Unexpected delays also need consideration.

A shipment scheduled to arrive overnight may encounter transportation or weather disruptions. Cold-chain planning should account for realistic shipping conditions rather than only the fastest possible delivery.

The goal is to maintain the required conditions until the product reaches the next controlled environment.

Different Dry Ice Formats Serve Different Needs

nexAir Carbonic supplies dry ice in several forms, including blocks, slices, pellets, nuggets, and Cryo Rice.

Those options allow customers to select formats appropriate for different applications and packaging configurations. Blocks can provide long-lasting cooling, while smaller formats can provide greater contact around products or fit differently within shipping containers.

There is no single dry ice format that is automatically best for every pharmaceutical shipment.

The product, packaging, duration, temperature requirement, and available space all influence the choice.

Application knowledge helps companies determine the approach that makes sense for their operation.

Reliable Dry Ice Supply Supports Reliable Shipping

Pharmaceutical cold chains operate on schedules.

Products may need to leave a manufacturing facility at a particular time, research samples may need to reach a laboratory quickly, and healthcare shipments may be tied to patient or clinical requirements.

Dry ice supply has to fit those schedules.

Because dry ice continuously sublimates, companies benefit from working with suppliers capable of providing dependable product when shipments are being prepared.

nexAir Carbonic manufactures and supplies dry ice for healthcare, research, food, shipping, and industrial customers. That regional supply capability helps businesses throughout the Southeast plan dry ice availability around their operational needs.

Emergency Planning Matters Too

Cold-chain operations should also consider what happens when normal systems are disrupted.

A refrigeration failure, power outage, severe weather event, or transportation delay can create an immediate need for additional cooling.

Dry ice can provide temporary cooling without electrical power, making it useful as part of emergency temperature-control planning.

nexAir identifies emergency applications including protecting medicines and other temperature-sensitive materials during power outages and infrastructure disruptions.

For pharmaceutical operations, having a plan for obtaining additional dry ice can provide another option when normal refrigeration or transportation does not go according to plan.

Safe Handling Is Part of Dry Ice Planning

The properties that make dry ice effective also require proper handling.

At approximately -109.3°F, direct contact can cause cold injury. As dry ice sublimates, it releases carbon dioxide gas, which means appropriate ventilation and handling practices are important.

Shipping applications also need to follow requirements applicable to the product, package, transportation method, and destination.

Employees working with dry ice should understand the material and follow appropriate procedures for handling, storage, packaging, and transportation.

Cold-chain performance and good handling practices should always go together.

How nexAir Helps

nexAir Carbonic provides reliable dry ice supply for pharmaceutical, healthcare, research, food, transportation, and other temperature-sensitive applications.

Available formats include blocks, slices, pellets, nuggets, and Cryo Rice, giving customers options for different cooling and shipping requirements.

nexAir also provides consultation, training, and application support through nexAir KnowHow. For pharmaceutical and biotechnology organizations that also depend on specialty gases, nexAir supports high-purity gases, NIST-traceable calibration mixtures, and custom-engineered blends through ISO/IEC 17025:2017-accredited laboratories in Memphis and Atlanta.

Together, those capabilities allow nexAir to support several parts of pharmaceutical and life science operations—from analytical work in the laboratory to temperature-sensitive materials moving through the cold chain.

Helping Customers Forge Forward

nexAir customers Forge Forward by building dependable temperature control into pharmaceutical shipping.

Reliable dry ice supply, appropriate formats, careful planning, and experienced support help businesses protect temperature-sensitive products as they move between laboratories, manufacturing facilities, distribution points, healthcare providers, and other destinations.

Pharmaceutical shipping may happen outside the laboratory or production facility, but it is still part of protecting the product.

When temperature matters, the cold chain matters too.
