Frequently asked questions
When should I choose -86 °C storage instead of -20 °C or -40 °C?
ULT storage at around -80 °C is typically selected when long-term sample stability is critical. The choice depends on sample type, required storage duration and internal quality protocols.
How do I determine the right freezer capacity?
Consider the number of storage boxes or racks, expected growth in sample volume and how frequently the freezer will be accessed. Selecting sufficient capacity helps maintain an efficient and organized workflow.
Which monitoring and alarm options are important for ULT storage?
Many laboratories require configurable alarms, temperature logging and connectivity to external monitoring systems. Share your monitoring requirements with us so we can advise on suitable configurations.
Are these ULT freezers suitable for biobanking applications?
Yes, Vestfrost ULT freezers are commonly used in biobanking environments. Proper internal organization and defined handling procedures are key to effective long-term sample management.
