Scientifically Backed & Technologically Advanced:HB ULT Freezers

✅ Why Use ULT Freezers?

Across Africa, public health systems are facing mounting challenges:

• Recurring outbreaks of viral diseases such as Ebola, Marburg, and yellow fever continue to drive the demand for high-performance sample storage solutions.

• Vaccination coverage remains low, and the cold chain infrastructure for vaccines is urgently in need of upgrades.

• While molecular diagnostics (e.g., PCR testing) are becoming increasingly widespread, secure transport and storage of critical reagents remain severely inadequate.

Global research points to one consistent finding: the colder the storage temperature, the more stable the samples.

1. Significant improvement in virus storage stability

• A study in Merck's Bioanalysis (2022) tracking the long-term storage of 271 virus batches across varying storage temperatures clearly indicated that:

👉When stored at -70°C or below, viral titers retained more than 99% of their integrity after 10 years, and approximately 73% even after 30 years.

2. Superior storage stability for nucleic acid reagents and molecular materials

• Multiple studies published on SpringerLink further confirms that:

👉RNA samples are highly temperature-sensitive, with noticeable degradation observed at temperatures below -20°C. The optimal range for long-term storage lies between -70°C and -80°C.

👉Lyophilized reagents and proteins exhibited slower degradation when stored below -80°C, effectively extending their usable life by three to five times.
