ELODIZ DUPLA™ Raman
The ELODIZ DUPLA™ is the second compact multi-laser system from our line of Raman devices. The product provides long-term operational stability 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. Two 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.
Along with the stand alone laboratory bench device (white) we also offer a rack version (black) which can be mounted in a cabinet for industrial application.
DUPLA™ system requires 2 independent fibre probes for operation.
