We’re delighted to announce the launch of our ULT Freezer Range – available in 80L and 208L capacities – designed and developed in line with MHRA guidelines to give you confidence at the lowest temperatures.
What are Ultra-Low Temperature (ULT) Freezers?
ULT Freezers are designed to store biological samples, vaccines and research materials at ultra-low temperatures, typically around -86°C. At these extreme low temperatures, degradation is halted, meaning samples can be preserved safely for extended periods whilst biological activity is halted. This makes ULTs essential for:
- Biopharmaceutical companies
- Academic and Research institutions
- Hospitals and Clinical Labs
- Biobanks and Repositories
- Government and Public Health Agencies
- Contract Research Organisations (CROs)
Critical samples stored at these temperatures includes:
- RNA and DNA samples – these are highly sensitive to temperature fluctuations and require stable, low temperatures to prevent breakdown
- Protein and enzyme preparations – for pharmaceutical formulation and biochemical research
- Vaccine storage – includes mRNA-based vaccines which require ultra-low temperatures to ensure efficacy
- Microbial strains – includes bacteria, fungi and viruses used in research
- Clinical trial samples – where long-term stability is essential for accurate testing results
- Tissue samples and cell cultures – for applications including cancer research and drug research and development
Designed and developed for confidence at the Lowest Temperatures
Available in both 80L and 208L capacities, our ULT Freezers have been designed in line with MHRA guidelines to ensure reliability from installation. Key Product features include:
- Powerful & Efficient Cooling – Patented dual-stage cooling systems delivers stable, ultra-low temperatures
- Premium Build Quality – Stainless Steel Interior and copper tubing for maximum durability and hygiene. Inner doors help maintain stable temperatures.
- Smart Safety Features – Built-in alarms for temperature changes, power failures and sensor issues – so you’re always in control.
