3. Product Description
The single block (N2400-4001) and dual block (N2400-4002) units use interchangeable heating block
modules for a variety of applications, including restriction digests, denaturing DNA, BUN, melting agar,
coagulation studies, in-situ hybridization and Hot Start thermo-cycler reaction, as well as having the ad-
ditional function of being used as a water bath. All models incorporate a PID controller for easy tempera-
ture selection, rapid heat-up, and excellent stability. Temperature may be set in 0.1 ºC increments, from
5 ºC above ambient to 150 ºC. The timer can be set from 0 to 999 minutes for the user’s convenience.
