Cora 5001 is a Raman analyzer for the quick and reliable identification of substances based on their unique chemical fingerprint. Choose the Fiber model for flexible analysis outside the instrument via a probe or the Direct model which analyzes samples in a closed compartment and has a laser Class 1 for the safest use. The guided analysis procedure means Cora 5001 is suitable for operation by personnel with minimum training. The small footprint and battery option make these benchtop Raman instruments versatile tools for analytical tasks in-house or in the field.

Key features

Easy and safe – excellent user guidance and laser Class 1

Easy and safe – excellent user guidance and laser Class 1

The handling of the Cora 5001 Raman spectrometers can be learned within minutes, even by inexperienced users. Your new employees or students are able to perform Raman spectroscopy measurements within a very short time. In contrast to many handheld instruments, the Cora 5001 Direct Raman instruments provide extra safety due to specified laser Class 1. The laser can only be activated if the measuring chamber is closed and therefore poses no threat to people working in close vicinity to the device.

No sample preparation – accessories for every sample type

No sample preparation – accessories for every sample type

Regardless of whether the sample is a solid, liquid, or powder, Cora 5001 has the appropriate sample holder for it. You can use vials with various diameters and shapes (round, square, rectangular) or directly analyze solid samples (pills, sample carriers, etc.). Equipped with magnets, the holders are quickly and precisely positioned in the instrument, allowing for immediate sample measurement without refocusing.

Versatility in a nutshell – one instrument, many samples

Versatility in a nutshell – one instrument, many samples

Do you work with fluorescing substances or many different samples? To cover the widest range of samples and account for possible fluorescence the “dual-core Raman” option gives you two different wavelengths in one instrument. Each Raman core is a fully equipped independent optical spectrometer system. Hop from one wavelength to the other at the click of a button without alignment or recalibration and analyze the whole range of substances.

Maximum robustness – no moving parts

Maximum robustness – no moving parts

The Cora 5001 series of portable Raman spectrometers is unaffected by shocks and vibrations and ready to work with you in the warehouse or in a busy laboratory. There are no moving parts and all sensitive optical components are protected within the optical bench which is a solid block of machined aluminum.

Autofocus – gets the strongest signal for reproducible results

Autofocus – gets the strongest signal for reproducible results

Manual focusing on thin or opaque samples with a weak Raman signal can be tricky. The Cora autofocus feature finds the spot with the best Raman signal within seconds so you don’t have to worry about it. With Cora 5001 you scan, it matches, and the task is done.
