The ESAW Spectrum Tubes (SW-2886 Series) are high-quality evacuated glass discharge tubes designed for physics and chemistry experiments. Each straight-form tube measures 20 cm in length with metal cap electrodes at both ends, and includes a 50 mm fine central capillary that highlights the discharge effect clearly.

These tubes are filled with different gases or vapors, making them ideal for studying spectral lines, atomic structure, and discharge properties:

• SW-2886/1 – Oxygen

• SW-2886/2 – Helium

• SW-2886/3 – Nitrogen

• SW-2886/4 – Ammonia Vapours

• SW-2886/5 – Carbon Dioxide

• SW-2886/6 – Iodine Vapours

• SW-2886/7 – Water Vapours

• SW-2886/8 – Mercury Vapours

• SW-2886/9 – Neon

Use Cases

• Students: Learn spectroscopy, electron discharge, and energy levels.
