Handheld Raman Spectrometer 

Serstech Arx+

Serstech Arx+ is a revolutionizing instrument, introducing SharpEyeTM – a patented autofocus technology for handheld Raman instruments. Serstech Arx+ will make it easier to identify and verify substances.

Serstech Arx+

Serstech Arx+ is packed with new features, simplifying the workflow when verifying substances at incoming goods inspection. Serstech introduces SharpEyeTM, a patented autofocus technology that improves the signal quality dramatically. With the new and powerful algorithms, Serstech Arx+ finds precise results for both single substances and for complex mixtures.

Serstech Arx+ is compliant with Title 21 CFR part 11 and equipped with an integrated barcode reader which makes it possible to tie a measurement to a container by scanning barcodes or QR codes. Specifically developed for the Pharma industry.

New UX. Serstech Arx+ is built on a modern software platform, putting usability and algorithms in focus. The brand new graphical user interface is easy to navigate and new features such as Guided Scan and the Quick Access feature make it possible to get precise results, faster. The new algorithms result in fast and precise identifications of both pure samples and complex mixes of substances. The results are presented in a simple way, making it possible for almost anyone to interpret and use. Decision support in seconds.

Truly handheld. Serstech Arx+ is lighter and smaller compared to previous Serstech models and yet – even more powerful. Serstech Arx+ lets you get focused on what is important and make decisions based on reliable measurement results – wherever you are.

Easy to use. Serstech Arx+ is easy to understand and gives accurate responses in seconds. Connect it wirelessly or via cable to ChemDash for reporting and management of users, measurements and libraries. Serstech Arx+ has been designed from the ground up to support a highly efficient workflow!
