CHRONECT Robotic DHR is a special model of the series that has two injection heads. These two heads can be moved simultaneously. This makes the DHR the ideal system to create automation solutions for high throughput. The two injection heads can either be equipped with manual tool change, similar to the RSI, or with the possibility of automated tool change, similar to the RTC. All tools and options are available for the system. The DHR is deliverable in the lengths 120, 160 or 200 cm.

The absolute highlight of the system is the ability to move two injection heads simultaneously. To make this possible, the control software CHRONOS has been completely revised. The calculation of the timetable generates two independent timetables; for each injection head separately. This ensures an optimal use of the available resources.

In order to ensure process reliability during simultaneous work and to avoid problems in the process, the DHR has an integrated collision control. Resources shared by the two heads at the crosshead are constantly monitored. An injection head can only access it if the other head does not occupy this resource. This simplifies method development enormously, as the user does not have to consider the possibility of a collision when creating the method.

The DHR is an ideal platform for automation in chromatographic laboratories that require medium to high sample throughput.
