The small one and the big one

The heating block NANOCOLOR® VARIO C2 enables the simultaneous digestion of up to 12 samples. For a higher sample throughput the NANOCOLOR® VARIO 4 is perfectly suited, as it allows up to 24 simultaneous digestions in two separately controllable heating units. Therefore, MACHEREY‑NAGEL offers the appropriate heating block to each user for routine analysis in the laboratory. The NANOCOLOR® heating blocks are equipped with lockable protective lids and a touch protection for increased work safety.

Extremely versatile and maximally secure

In addition to the preprogrammed temperatures and heating times, a large number of user-specific digestion methods can be stored. The USB and RS232 interfaces allow an easy connection to a PC and enable the convenient linkage to the NANOCONTROL® inspection equipment monitoring tools. The graphical representation of the heating curves enhances transparency about the temperature stability. The electronic overtemperature sensor protects the heating block from overheating.

Temperature testing and calibration

A temperature test can be performed using the NANOCOLOR® T‑Sets to safeguard results against authorities and supervisors. The free PC software of the heating blocks facilitates checking of temperatures and the creation of the respective reports. After measurement data transfer via the interfaces using the PC software, the testing certificate is created directly, which ensures a GLP-compliant documentation of all equipment testing.
