Eisco Premium Spectrum Tube Power Supply
The 26 cm spectrum tube power supply is designed for gas discharge experiments. It provides a high voltage output (approximately 5000 volts) suitable for lighting gas discharge spectral lines in connected tubes. The unit is CE, CSA, and CUS approved, meeting common electrical safety standards. Tube sockets are spring-loaded for easy placement and removal, with shielding to protect users from accidental contact. This setup is ideal for classrooms and lab demonstrations where safe operation is a priority while observing gas emission lines.
Eisco Krypton Spectrum Tube, 26cm
Designed for clear spectral observations, this krypton spectrum tube features a larger viewing area and high-clarity bright lines. When used with a compatible spectrometer and a diffraction grating around 5000 lines per inch, it offers optimum line resolution. The tube integrates with a purpose-built spectrum power supply and benefits from guidance on cyclic operation to extend tube life, suggesting operational patterns like 30 seconds on, 30 seconds off for extended use.
Yantra 110 V AC Spectrum Power Supply Kit
This kit includes an intensity-control powered spectrum supply and a complete set of 22 spectrum discharge tubes with unique gases. The package covers gases such as carbon dioxide, nitrogen, oxygen, neon, argon, chlorine, and more, providing a broad range of spectral lines for comparative study. The kit is designed for learners who want hands-on access to multiple gas emissions and the ability to adjust light intensity during observations.
Nitrogen Spectrum Discharge Tube
The nitrogen discharge tube offers a non-toxic option with a straightforward form factor (approximately 10.25 inches long). It supports observation of nitrogen emission lines under appropriate excitation and is suitable for foundational spectroscopy practices. Its dimensions and safety attributes make it a practical addition to student labs seeking consistent nitrogen spectra without complex setup.
Yantra 22 Set Spectrum Discharge Tube Kit
This collection provides a 26 cm spectrum tube with a central 10 cm capillary to aid wavelength observation, plus side electrodes for conductivity. The kit uses glass that remains transparent and heat-resistant, valuable for spectral studies. The 22 gases included offer a broad spectrum of emission lines, enabling students to compare line positions, intensities, and spectral patterns across different substances. The kit complements a student-grade spectrometer and standard diffraction gratings for effective analysis.
Eisco Oxygen Spectrum Tube, 26cm
This oxygen spectrum tube shares the high viewing area and clarity found in Eisco’s line, designed to deliver bright-line spectra at appreciable intensities. When paired with a compatible spectrum power supply and a student-grade spectrometer, users can observe distinct oxygen emission lines and compare them with other gases under identical experimental conditions. The documentation emphasizes a structured approach to cycling operation to protect tube life while obtaining reliable data.
Eisco Nitrogen Spectrum Tube
This nitrogen-focused tube complements the oxygen and krypton options by offering robust nitrogen emission observations. The product highlights a design that emphasizes clear line visibility, with a recommendation to use a power supply tailored for spectrum tubes to maximize intensity and stability of observed lines. It serves as a practical, non-toxic option for classroom demonstrations and basic spectral analysis.
Buying Guide
Key purchase considerations help buyers select the most suitable gas discharge spectrum kit for their needs:
- Gas variety vs. single-gas emphasis: Kits range from single-gas tubes to multi-gas sets. Decide if you need broad spectral comparisons or focused study on one gas.
- Power supply compatibility and safety: Look for CE/CSA/CUS ratings and shielded tube sockets. Ensure the supply voltage matches your region (110–120 V or other).
- Tube size and viewing area: Many 26 cm tubes offer larger viewing areas; larger diameters can ease alignment with a spectrometer.
- Spectrometer compatibility: Confirm the diffraction grating density (e.g., around 5000 lines per inch) and ensure the setup matches your instrument’s capabilities.
- Operating instructions: Some tubes benefit from cyclic operation (e.g., 30 seconds on/off) to extend life. Follow the manufacturer’s guidelines for best results.
- Safety and maintenance: Use appropriate eye protection and ensure shielding is intact. Handle glass tubes with care to prevent breakage and exposure to gases.
- Educational depth: Kits with 22 gases or varied options provide richer demonstrations, enabling comparisons of emission patterns across elements and compounds.
- Budget and space: Consider your lab or classroom space, storage needs, and the total number of tubes and power supplies included.
When comparing products, assess how each option aligns with your learning objectives: whether you prioritize a broad gas catalog, higher clarity in spectral lines, ease of use in a classroom setting, or compatibility with existing spectrometers. The selections above provide a spectrum of choices—from complete power-supply kits to focused gas tubes—to support practical spectral analysis and observation.
