you say you have broken glass basters before? was it during the blast? What happened. I have been blasting for a little over a year now and have only used glass twice.
We have our own tubes made out of heavy walled borosilicate tubing (Pyrex), and when we first started making them, I broke four tubes at the injection nozzle, because of the embrittling effects of the R-600 butane refrigerant chilling of the glass.
We changed the injection end design to maintain uniform thickness and a full radius on the closing end, so as to more evenly distribute expansion and contraction stresses.
When the glass is embrittled by temperature, it doesn't take much of a wiggle at the injection port to flake off a piece of the glass, unless the injection port is designed to minimize effect.
A stainless turkey baster doesn't suffer from the same pitfalls, so you might check it out. If you are willing to keep it free of oxidation, copper also works well without breaking.
I use all three. Hee, hee, hee............
Second to improper annealing, uneven wall thickness is the biggest weak point in homeade glass stuff.
The one I bought is thin, but was made for high temp applications. So far so good. Half dozen runs or so....cant remember....lol
It was 4 bucks...I pay $65 for a case of vector...:thinking:mad0229:
If it busts... it ok. I bought 6 of them...:winking0067:

What do you mean free of oxidation? How do you get around that problem?
Hey all I live in BC and developed a kick ass stainless extraction tube.I have receiver very good feedback as it is the third design so I have started to sell them and am doing quite good.
Not made with parts from hardware stores. never need to replace anything but butane. comes with screens. Unique designed for best end product.

thanks
so what do you do with the baster? does vector nozzle fit right on there or does one need to make something? what do you use for a filter?
