How To Collect And Preserve Tissue Samples
In general, the collection and storage of biological samples for advanced genetic manipulation and research often requires the collection of ultra-low temperature equipment to store and delay bioprocessing in blood and tissue samples. The primary mission of extracting and preserving this DNA is necessary to study the sample population.
Although biological iced tissue specimens are collected for molecular research and clinical studies, conservation can also be used to understand the science of biological samples. The process of preserving animals, skins, or liquids for long-term storage requires specialized collection, statistical analysis, and research procedures.

Biological materials must be stored for a certain time at a certain temperature. In general, products that are stored for a short period of time should be frozen for a long period of time or refrigerated in order to be used quickly. While some shipping containers use dry ice to control temperature, the Stirling Ultracold ultra-low temperature freezer is ideal for storing samples in almost any application.
Insulated cold chain conveyance containers often rely on a combination of high-quality insulation and phase change materials for thermal protection and transport of temperature-sensitive biological products from production to patients. For ultra-cold storage requirements, dry ice is often used as a phase change agent as it sublimates at -70 °C.
Freezing of whole specimens should be avoided when histopathology is required "because it causes multiple artifacts". Since storage for a shorter period of time does not require treatment intensification, immediate preservation of DNA samples may be the simplest procedure. If the sample is to be stored for an extended period of time, it should be stored in an ultra-low freezer such as the Stirling Ultracold.
