Description
The GBS-1 Automatic Rotary Ampoule Flame Sealing Machine is a compact, high-efficiency thermal sealing device for glass ampoules and tubular glass bottles.
As a dedicated ampoule flame sealer, this unit runs on liquefied petroleum gas or natural gas to create concentrated heating flames. Its built-in air supply system maintains steady combustion and precise neck sealing, producing results matching full industrial automatic ampoule sealing equipment.
Built-in automatic bottle rotation delivers balanced heating across glass necks and cleaner, more uniform sealed finishes, with sealing quality comparable to large fully automatic machines.
This bench-top sealing unit targets laboratory scenarios and sees wide use in pharmaceutical research labs, hospital pharmacy preparation rooms, educational institutes and small-batch production lines.
Operation Guide for Gas Flame Ampoule Sealer
- Liquefied petroleum gas or natural gas generates focused sealing flame.
- A motor drives the ampoule fixture to rotate at a fixed constant speed.
- The ampoule neck heats evenly until glass turns soft and malleable.
- Operators stretch the softened glass with stainless steel tweezers.
- Secondary flame treatment smooths the bottle tip to remove rough crystal textures.
Operation Tips
For first-time use, slide bottles slowly into the fixture and guide them toward the flame zone. Check for off-center rotation and record the heating time needed for the neck to glow red hot.
Once the heated neck softens and sags downwards, pull the glass outward with tweezers. Do not remove the bottle from the flame immediately after stretching. Keep the tip under flame until all crystalline edges melt into a smooth rounded seal before taking it out.
Detailed, easy-to-follow operation manuals come standard with every unit after purchase.
