How to Use the Pneumatic Trough Glass 125mm

1. Confirm the approved experiment method, gas type, and required accessories before use.
2. Inspect the glass trough for cracks, chips, sharp edges, or instability.
3. Place the trough on a flat, stable laboratory bench away from bench edges.
4. Add water only to the level required by the practical method.
5. Set up compatible gas jars, covers, delivery tubes, and supports as directed by the teacher.
6. Collect gas only under supervised and ventilated laboratory conditions.
7. Use a suitable safety screen for demonstrations involving reactive materials such as alkali metals.
8. Empty, clean, dry, and store the trough after the practical is complete.

Safety note: Wear goggles, gloves, and a lab coat during gas preparation experiments. Do not use the trough with pressurised, toxic, flammable, corrosive, or unknown gases unless the method is approved and supervised. Alkali metal demonstrations must be carried out only by trained staff using a safety screen.

Care & Maintenance

• Wash the trough after use with a suitable laboratory cleaning method.
• Dry the glass fully before storage to reduce residue and contamination.
• Store away from impact, heavy loads, and abrasive contact.
• Remove cracked, chipped, unstable, or heavily scratched troughs from service.
