TwinFlow Heavy Duty Double Percolator Glass Bong — 30cm

Built for customers who want more filtration without moving up to an enormous glass piece, the TwinFlow Heavy Duty Double Percolator Glass Bong combines a substantial 30cm borosilicate glass body with two separate percolator stages. The straight chamber, wide base and built-in stem create a clean, purposeful design with plenty of visible glasswork.

Double Percolator Two filtration stages positioned through the main glass chamber.
30cm Heavy Duty Body A substantial full-size bong rather than a compact tabletop piece.
18.8mm Joint Larger glass connection specified by the supplier.
Two percs. Two filtration stages.

The defining feature of the TwinFlow is its double percolator system. Instead of relying on a single water chamber, airflow travels through two separate perc stages before reaching the upper tube, increasing contact with the water along the way.

Stage One The lower perc begins the diffusion process inside the main water chamber.
Stage Two A second perc adds another filtration point before airflow enters the upper chamber.
Heavy Duty Glass Supplier specifies heavy-duty borosilicate glass construction for the main body.
Built-In Stem Integrated stem keeps the profile clean and reduces unnecessary removable sections.
Assorted colours: supplier imagery shows blue, clear, dark green/teal and light green accent options. Select the available colour option when ordering.

Double percolator filtration

A standard bong generally relies on its main water chamber for filtration. The TwinFlow adds two dedicated percolator stages, dividing airflow into smaller bubbles and increasing its interaction with the water before it reaches the mouthpiece.

That makes this a useful step up for anyone comparing a basic straight glass bong with a more advanced double percolator bong.

Why choose the TwinFlow?

  • Twin perc system: two separate filtration stages rather than a single perc.
  • 30cm height: substantial full-size proportions without becoming excessively tall.
  • Heavy-duty borosilicate glass: robust glass construction specified by the supplier.
  • 18.8mm joint: larger fitting than many compact 14mm glass bongs.
  • Built-in stem: gives the bong a clean one-piece main body.
  • Wide glass base: provides a stable footprint for the tall cylindrical chamber.
  • Glass bowl included: supplied with a standard removable glass bowl.

A proper step up from a basic bong

At 30cm tall, this is considerably more substantial than the 16–20cm compact pieces. More importantly, the extra size is actually being used for filtration: the tall chamber houses the two separate perc stages rather than simply adding an unnecessarily long neck.

Heavy-duty borosilicate glass

The supplier describes the TwinFlow as being made from heavy-duty borosilicate glass, a material commonly used for quality glass waterpipes because of its durability and resistance to temperature changes.

Care & cleaning

  • Empty used water after each session.
  • Remove the glass bowl before deep cleaning.
  • Rinse the main chamber regularly with warm water.
  • Use an appropriate glass bong cleaner for heavier residue.
  • Ensure cleaning solution reaches both percolator stages.
  • Rinse both chambers thoroughly after cleaning.
  • Allow the bong and bowl to dry fully before storage.
