19BT78 is a lower hemispherical heating mantle and SDC temperature controller with digital Fahrenheit display and K-Type thermocouple designed to heat 1000 ml round bottom glass flasks. Great for use with basket ring stands, this low-watt density heating mantle is an ideal alternative to traditional Bunsen burners. The knitted heating element is capable of temperatures up to 842° F (450° C). SDC benchtop digital controllers are easy to use and programmable with a self-contained, plug-and-play design.

About Lower Hemisphere Heating Mantles
The Cary Company's heating mantles offer uniform heat distribution for round-bottom flasks. Lower hemispherical heating mantles are an excellent alternative to heating methods with an open flame such as a Bunsen burner.

These heating mantles feature a uniform, low-watt density knitted and braided heating element capable of temperatures up to 842° F (450° C). The multi-stranded resistance wire offers increased durability and flexibility. Lower hemispherical heating mantles are ideal for use with a basket ring stand.

About BriskHeat® SDC Benchtop Digital Temperature Controllers
BriskHeat® SDC benchtop digital temperature controllers are affordable and compact controllers for a wide range of general-purpose heating applications. Ideal for applications requiring automatic control, these digital controllers are easy to use and programmable with a self-contained, plug-and-play design.

SDC temperature controllers feature password protection for additional security and a sensor break operation option. These controllers have an audible alarm that can be programmed for high or low range. Models come with either a Fahrenheit or Celsius display. The Fahrenheit models offer a temperature control range from 32° F to 999° F and the Celsius models have a 0° C to 700° C. Accuracy is +/- 1% full span.

Each benchtop digital temperature controller comes with a factory installed sensor input. Thermocouple options include a Type-J or Type-K sensor. These benchtop temperature controllers are ideal for indoor use with an operating temperature range of 32° F to 158° F and a storage range of -4° F to 176° F. Relative humidity should be less than 80% in non-condensing temperatures.
