Description
Sigma 4-5KL is a benchtop refrigerated centrifuge designed for laboratory separation tasks that require controlled cooling. Operating at 200 V and 50/60 Hz, this compact floor- or bench-friendly unit supports routine sample processing in clinical, research and industrial environments where temperature-sensitive materials must be centrifuged under defined conditions. As a refrigerated table-top model it combines cooling capability with the convenience of a space-saving benchtop footprint, making it suitable for laboratories that need reliable cold centrifugation without a large floor-standing system. The Sigma 4-5KL belongs to the established Sigma centrifuge range and is intended for everyday use with compatible rotors and accessories according to laboratory protocols. Powered for 200 V mains supply at both 50 Hz and 60 Hz, it fits common laboratory electrical infrastructures. Ideal for workflows involving temperature-critical samples, the instrument provides a practical refrigerated centrifugation platform for facilities seeking a dedicated benchtop cooler centrifuge from manufacturer Sigma for standard laboratory applications.

What is this article?
Sigma 4-5KL, refrigerated benchtop centrifuge, 200 V, 50/60 Hz is the article on this page. Luminix Health distributes Sigma for laboratory use. It sits in Circulators, chillers & thermostats, inside Heating, drying & cooling, in Lab instruments.
A circulator or thermostat holds a bath liquid at a set temperature and pumps it through a jacket. A chiller is the same idea aimed below ambient. The temperature range, the cooling power and the pump flow are the three numbers. The fluid has to match the range.
Temperature equipment either holds a set point or drives a sample toward one. An oven dries. A furnace reaches the temperatures of ashing and melting. A bath surrounds a vessel with water or oil. A circulator moves that fluid. An incubator holds the mild warmth of a culture. An autoclave uses steam under pressure to sterilise. The number that matters is the temperature the article actually reaches, not the number painted on the dial. Temperature is part of the international system kept by the BIPM and compared by EURAMET.
