HiSi beakers
Beakers give a wide, stable base. Choose the 15" Double U Perc Beaker for a mid-size piece, the 16" Double Bell Perc 2.0 Beaker, the 19" Triple Bell Perc 2.0 Beaker, or the tall 21" Triple Mushroom Perc Beaker.
HiSi Glass
Curated by the Angies Boutique buyers. HiSi scientific glass: thick 50x5mm beakers and straight tubes with bell, U and mushroom percs, plus HiSi step diffuser downstems and drain bowls.
HiSi Glass: Bell Perc Beakers, Straight Tubes, Downstems & Drain Bowls
HiSi Glass makes scientific water pipes built around stacked percolators: bell percs, U percs and mushroom percs that split smoke through several chambers for a smooth, filtered hit. The big pieces use heavy 50x5mm tubing with ice pinches and splash guards, and the beakers we carry come with a HiSi step diffuser downstem and drain bowl (check each listing for what is included).

HiSi straight tubes
Straight tubes clear fast and take up less table space. The 16" Jr. Triple Bell Perc 2.0 Straight is the compact option on 44x4mm tubing, while the 21" Triple U Perc Straight and 22" Triple Bell Perc 2.0 Straight are full-size 50x5mm tubes. See more on Scientific Glass and Water Pipes & Bongs.
HiSi downstems and drain bowls
HiSi step diffuser downstems come in 4.0", 5.5" and 6.0" lengths for replacing or upgrading a stock downstem. The HiSi Drain Bowl, 14mm has an 8-hole design that keeps ash out of your water. More on Downstems and Bowls & Slides.
HiSi percolators explained
| Perc | How it works | Feel |
|---|---|---|
| Bell perc | Smoke pushes down through a bell-shaped chamber and out through slits around its base | Smooth, steady bubbles |
| U perc | A U-shaped tube with slits that spreads smoke across the water | Quick clearing with good diffusion |
| Mushroom perc | A dome-capped perc that bounces smoke through the water | Heavier filtration |
| Double or Triple | Two or three percs stacked in one tube | More filtration, slightly more drag |
More percs means cooler, more filtered hits; fewer percs means an easier pull. A double perc is a good middle ground for daily use.
Caring for HiSi glass
- Fill water just over the bottom perc and the downstem slits.
- Clean with warm, not hot, isopropyl alcohol and fine salt, shaking gently so it reaches every perc chamber.
- Avoid sudden temperature changes, especially when using the ice pinches. See Cleaning Supplies.
