Laboratory freezers provide indispensable storage space for everything from bulk reagents to delicate tissue samples. Lab freezers can be chest format or upright. They are typically equipped with adjustable shelves designed to accommodate multiple types of sample containers. Programmable thermostats and temperature monitor systems, as well as alarms that sound in cases of power failure are common features. Standard freezers maintain a temperature just below freezing. Ultra low freezers, capable of temperatures of -80 degrees Celsius or lower, are available and often used for high-value samples. Freezer prices can vary widely depending on the temperature model. General-purpose freezers may fall in the low $1,000 range, while higher-end ULT and cryogenic freezers can cost upwards of $30,000 and more.
