While dealing with the preservation of biological samples, it is important to note that the quality of the preservation will depend on the process employed. There are two main types of laboratory storage. These include physically held or more formally referred to as storage in liquid nitrogen. While stored in liquid nitrogen can keep samples intact, the sample must still be physically moved from the lab for analysis, and there is no guarantee that samples will be free of microbial contamination.

The second type of preservation is that of freeze-drying. This method involves the drying of samples in a low-temperature environment and involves physically moving the samples from the labs for analysis. The technology behind this method is called sublimation. The advantage of sublimation is that it doesnot require the selection of a specific culture medium and does not result in microbial contamination.

All of these methods have their pros and cons, so it is imperative that a study be performed on a lab to determine whether these procedures are suitable for the site. Lab components for experiments include pumps, conditioning and filtration systems, immunoassays, and gas chromatography. Research studies involve specialized equipment such as microscopes, and the management of these materials requires planning and handling.
