WARNING: CARE MUST BE TAKEN WHEN SEALING AMPOULES AMPULES BECAUSE GLASS REMAINS HOT AFTER SEALING

Ensure valves are shut
Connect the gas and compressed air and set pressures
Open the gas and air valve and light flame
Adjust gas and air to obtain a flame with inner cones of approximately 5 mm and the ends of the flame just overlapping
- Note: If the flames curl up there is too much gas
Adjust the height of the ampoule ampule rest so the flames play onto the narrow part of the neck of the ampoule ampule where the seal is to be formed
Place the ampoule ampule in the flames and rotate the base of the ampoule ampule slowly
When the glass stem starts to glow red, use tweezers to hold the top of the ampoule ampule whilst still rotating the base. Draw off the top as the glass softens. Practice will be needed to form a good seal.
