Ni-Cr string for spectral analysis

Product Code : SCL-OS-12852

The Ni-Cr Wire for Spectral Analysis by Educational Instrument is a practical spectroscopy accessory for chemistry and physics laboratories. Nickel-chromium wire is commonly selected for flame-test work because it withstands repeated heating better than ordinary metal wire and can be cleaned between demonstrations.

This product supports hands-on learning in spectral analysis, analytical chemistry, and atomic physics. It may be used with suitable burners, sample salts, a spectroscope, diffraction gratings, or related optics apparatus when the lesson requires observation of emission colours and spectral behaviour.

Key Features

How to Use the Ni-Cr String for Spectral Analysis

Cut or select the required length of Ni-Cr wire as instructed by the teacher or laboratory manual.

Hold the wire with suitable tongs, a holder, or an insulated support.

Clean the wire by heating it until no visible colour contamination remains.

Dip or touch the cooled wire to the prepared sample according to the experiment procedure.

Place the sample-bearing wire carefully in the flame and observe the colour produced.

Use a spectroscope, spectrometer, grating, or prism setup if the experiment requires spectral line observation.

Record the observed flame colour or spectral pattern and compare it with the lesson reference table.

Safety note: Use this wire only under teacher or laboratory supervisor guidance. Heated Ni-Cr wire can cause burns. Wear eye protection, avoid inhaling fumes, and handle chemical samples according to the laboratory safety sheet.

Care & Maintenance

Clean the wire after use to reduce cross-contamination between samples.

Store the wire in a dry, labelled container away from corrosive chemicals.

Do not touch hot wire directly; allow it to cool before storage.

Discard damaged, heavily corroded, or contaminated wire according to laboratory rules.

Frequently Asked Questions

What is Ni-Cr wire for spectral analysis used for?

Ni-Cr wire for spectral analysis is used to hold small samples in a flame so students can observe flame colours or emission behaviour during spectroscopy experiments.

Why is Ni-Cr wire used in flame tests?

Ni-Cr wire withstands repeated heating and can be cleaned between samples. This makes it practical for supervised classroom flame-test demonstrations.

Can this wire be used in school laboratories?

Yes. It is suitable for senior school and college laboratories when used under teacher supervision with proper flame and chemical safety procedures.

Does the product include a burner or spectroscope?

No burner or spectroscope is confirmed here. The included quantity and accessories should be confirmed before ordering or final website upload.

Can this wire be used with an optical bench setup?

Yes, it may be used as part of a broader spectroscopy demonstration with an optical bench, spectroscope, prism, or diffraction grating where the experiment design requires it.

Is any certification supplied with the Ni-Cr wire?

No product-specific certification is confirmed. Certification or compliance details should be added only if the supplier provides verified documentation.
