This is a jar full of only water (liquid and vapor). It boils at any temperature when you apply something cold enough to the top, like ice.

I put water in a jar and sealed it while it was boiling, and now it boils at any temperature. Super fun demo to try.

Now I wonder if the pressure inside is low enough that you could reach the water’s triple point If you cool it down to 0,01°C

Yes definitely. The pressure will drop along the vapor pressure curve all the way to the triple point, gently boiling all the way if you remove the heat from the vapor and not directly from the water.
