General-purpose research equipment comes with features designed to serve various functions, such as cooling, heating, mixing and temperature management, required to conduct experiments and research. Drying ovens are available in various types, such as a compact desktop type. In addition, there are standard type ovens that can be used for a wide range of applications and automatic ovens that serve as dry heat sterilizers. Water purifiers are also a type of general-purpose research equipment. There are high-performance water purifiers with reduced TOC, microcontroller-enabled water purifiers with a small footprint and products that can be connected to a faucet to obtain pure water. Heating equipment is also a typical example of general-purpose research equipment. Heating equipment includes products that can reach the maximum temperature in about 30 minutes, products that can heat up to 300°C and products with an aluminum plate.
