Tabletop Ampoule Sealing Equipment Production Overview
The GBS-1 Automatic Rotary Ampoule Flame Sealing Machine is a compact and efficient ampoule sealing machine designed for thermal sealing of glass ampoules and tubular glass bottles.
As a professional ampoule flame sealer, the machine uses LPG (liquefied petroleum gas) or natural gas to generate a concentrated flame. The integrated air supply system ensures stable combustion and precise neck sealing, delivering results comparable to fully automatic ampoule sealing equipment.
Automatic bottle rotation ensures more uniform heating and a more aesthetically pleasing seal, achieving results comparable to an automatic sealing machine.
This tabletop ampoule sealing machine for laboratory use is widely applied in pharmaceutical research, hospital compounding rooms, educational institutions, and small-scale production environments.

How to use the Gas Flame Ampoule Sealer
The GBS-1 gas flame glass ampoule sealing machine operates using controlled thermal melting technology:
- LPG or natural gas generates a concentrated sealing flame.
- The motor drives the ampoule holder to rotate at constant speed.
- The ampoule neck is heated evenly until softened.
- The operator draws the softened glass using stainless steel tweezers.
- The flame smooths the tip for a clean, crystal-free finish.
This combination of uniform rotation and stable flame output ensures consistent sealing quality across batches.
Tip: When operating for the first time, slowly insert the bottle into the mold and push it into the flame. Observe whether the bottle rotates eccentrically and note how long it takes for the neck to become red-hot. Once the bottle neck begins to bend downward, use tweezers to draw the glass. After drawing the glass, do not rush to remove the bottle from the flame. Wait until the flame melts the crystallized tip at the top into a smooth finish before removing it.
★After purchasing the product, we will provide detailed and comprehensive instructions to guide you.
Ampoule Mold
The mold features four positioning screws with adjustable bottle clamping width for effortless insertion and removal. Through-hole machining minimizes eccentricity to the greatest extent.


Sliding rail
Push and pull back and forth. When pushed, it drives the flame's base to rotate the bottle; when released, rotation stops.
Driving Wheel and Driven Wheel
Contact rotation mimics the bottle rotation mechanism of fully automatic sealing machines, ensuring even heating of the bottle mouth for smoother sealing and results comparable to automatic sealing machines.
