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.
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.
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.
