Research Laboratory Freezers

Working in scientific and research laboratory fields often requires a safe and secure place to store different biological materials, products and samples. Temperature fluctuations can impact the viability of these sensitive materials, causing the shelf life to shorten, degrading biospecimens and even reducing a biological product’s effectiveness. It is very important to choose a high-performance freezer that can handle the requirements of your laboratory.

Ultra-low temperature (ULT) freezers are designed to provide a dependable solution for temperature control and preservation of research sample products. Stirling Ultracold provides dependable freezers that are designed to store specimen inventories at a wider temperature range between -20℃ to -86℃. These ultra-low freezers are ideal for preserving tissue samples, proteins, cells, enzymes, chemicals and other biological materials in a laboratory or onsite at a clinic.
