ELODIZ DUPLA Raman

The ELODIZ DUPLA Raman system is the only multilaser line of compact Raman devices to offer research-grade performance whilst maintaining ease of use. The product can detect low levels of signal and provides long-term operational stability features, that are required in a broad number of applications, which makes DUPLA the ideal partner for general material characterisation and reaction monitoring processes.

Often, the use of a single laser line might not be sufficient and multiple readings are necessary (e.g., teaching laboratories, quality assurance services or quality control support laboratories, scale-up process). Our multichannel device, which does not require any user manipulation during operation, offers versatility where productivity and multipoint data access is critical. 2 independent fibre probes which can be connected to this device provide a choice of either simultaneous or independent operation.

Why work with complicated modular DIY setups or waste resources on multiple units? ELODIZ multi-laser lines (NEEGALA™ & DUPLA) allow expansion of operations while reducing the need for complicated or cumbersome devices.

DUPLA system requires 2 independent fibre probes for operation.

NOTE: NEEGALA™ probe is not compatible with DUPLA system.
