Applicable for Upstream + Downstream

Portable dual-laser spectrometer


The DUPLA system is incredibly versatile and open to a wide range of applications due to the integration of multiple laser lines in a single device that doesn’t require any user manipulation.

Multi-channel raman device

The DUPLA system’s long-term operational stability makes it the most appropriate companion for general material characterisation and reaction monitoring processes.

A single laser line may not be adequate, and multiple readings may be required. The DUPLA multichannel device offers adaptability when productivity and multipoint data access are essential because it does not require any user manipulation while in use. The device can be connected to two independent fibre probes, giving users the option of simultaneous or independent operation.

In addition to the standard standalone lab bench device in white, we also provide a rack version in black that can be mounted in a cabinet for industrial use.

Please note that for the DUPLA system to function, two independent fibre probes are needed. In addition, the DUPLA system cannot be used with the NEEGALA probe.
