FAQs

Cryogenic storage is the process of preserving biological samples — such as stem cells, CAR-T cells, embryos, vaccines, plasma, and other sensitive materials. At ColdStash, our liquid nitrogen storage systems maintain temperatures as low as -196°C, ensuring maximum cell viability and biological sample preservation for long-term use. Cryogenic storage is essential in life sciences, biotech, and pharmaceutical industries where product integrity is critical.

ColdStash provides safe cryogenic storage solutions for:

• Cell and gene therapy products, including CAR-T cells

• Stem cells and cord blood

• Reproductive tissues (sperm, oocytes, embryos)

• Clinical trial samples, vaccines, and plasma

• Viral vectors and research materials

We serve biotech companies, pharmaceutical manufacturers, fertility clinics, hospitals, and research institutions worldwide.

While ultra-low temperature (ULT) freezers store samples at around -80°C, liquid nitrogen storage operates in the -150°C to -196°C range. These colder, more stable conditions stop molecular degradation, making LN₂ storage ideal for long-term biological sample storage. ColdStash LN₂ systems also operate independently of electricity, making them more reliable during power outages and superior for secure cryogenic shipping.

Yes,  we are embedded in several approved therapies. ColdStash’s secure/protective cassettes and canisters used in multiple clinical trials for these life changing therapies.

Our cryogenic shipping equipment consists of LN₂ shippers that maintain cryogenic temperatures for 5–10 days without electricity. This ensures cold chain logistics integrity during both domestic and international transport. Many companies add additional temperature monitoring, real-time tracking, and full regulatory documentation to ensure biological sample preservation from door to door.
