A labtop cooler -20 is a type of portable refrigeration device used in laboratory settings to store and transport temperature-sensitive samples or reagents. The “-20” in its name refers to its capability to maintain a temperature of -20°C, which is a commonly used temperature for storing and transporting materials that require ultra-low temperature storage.

These coolers are designed to be compact and lightweight, making them ideal for use in the field or in laboratory settings where space is limited. They typically have a small refrigeration unit, which is powered by an AC adapter or a battery, and are designed to maintain a constant temperature of -20°C to keep samples or reagents cool and protected.

Labtop coolers -20 are commonly used in a variety of laboratory applications, including storing biological samples, vaccines, and other temperature-sensitive materials that require ultra-low temperature storage. The use of a labtop cooler -20 helps to maintain the quality and stability of samples and provides a convenient and portable solution for maintaining a controlled temperature in the laboratory.
