Most of the glass tanks are Pyrex glass. Breakable but tougher than regular glass
I didn't break a single one.![]()
...but the glass is so thin it breaks if you stare at it.
I have one tank I simply refuse to use anymore. The Serpent SMM is a nice single coil tank, but the glass is so thin it breaks if you stare at it. Now I know why they included 2 spares instead of one. That's still not enough as every time you clean it it's time for another. I'm really gentle and take care of my equipment, but that design was just plain bad.
I have used my Serpent SMM all day every day for a bit over a year and only broke 1 tank. I was taking it off the mod to clean it, and dropped it from about chest height on a tile floor. That would have broken any tank. Still, it didn't shatter it just cracked and started leaking through the crack.
Now I will say that I >THINK< I heard somewhere that they changed the glass that they used in later production runs to something more durable. So maybe you have one of the earlier runs? If so maybe try some aftermarket glass.
