Remove trapped air in cylinder

[Andre_st]

Does anyone know how i can remove the trapped air in the top of the cylinder?
These cylinders are used for gases but are pressure tested with fluid. For testing, all air needs to be removed from the cylinder.

Fill while inverted.

The bottom of the cylinder has the same shape... so filling with the vessel upside down will also not work in this case

 

[3DDave]

Vacuum pump to remove the air and then fill with fluid.

There is usually an allowance for hydro of 0.1% air volume?

Or insert a U shaped tube / straw into the gap to get rid of the air.

I'm with LittleInch; J-shaped tube of correct radius, with cylinder slightly inclined from vertical to collect air to one pocket, should suffice.

I've gotten my share of blood draws, and the test tubes are evacuated so that it's easier to get blood from the turnip

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
