These versatile heating systems uniformly heat a wide range of test tubes simultaneously. Systems offer different combination of blocks for your specific needs. A complete heater system consists of a standard heater base and heating blocks (sold separately). Each block heater base features a stepless thermostat dial marked from 0 to 10 for repeatable settings. A separate power switch with power-on light operates independently of the thermostat dial.
Metal-sheathed safety heaters ensure temperature uniformity and rapid heating. Heater bases have steel housing with baked enamel finish, and include 6-ft, three-wire power cord; 115 VAC models include a plug.
