A labtop cooler is a portable refrigeration device used in laboratory settings to keep samples, reagents, or other laboratory materials cool. Labtop 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, usually between 2°C and 8°C, to keep samples or reagents cool and protected. Labtop coolers are commonly used in a variety of laboratory applications, including transporting and storing biological samples, vaccines, and other temperature-sensitive materials.

They can also be used to keep laboratory equipment, such as centrifuges or spectrophotometers, at a constant temperature, ensuring consistent and accurate results. The use of a labtop cooler helps to maintain the quality and stability of samples and provides a convenient and portable solution for maintaining a controlled temperature in the laboratory.
