test tube volume marking

[zorin]

Hay there!

we would like to mark laboratory test tubes with two lines which are representing volume. Do you have an idee if there exist some maschine / tool for test tube marking with some engraving / marking possibility.
We use test tubes only once and throw them away after.

Does sombody hase such experince / idee?
Buying test tubes is too expennsive!

Any idee sufggestion is welcome!
thanks

There are probably dozens of choices, given that this is the first hit on Google:

The biggest questions are:
> how accurate?
> how permanent, given a one-time use?

Seems to me that you should get them pre-marked from an OEM.

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

Perhaps it would be better to use an accurate dispenser to fill the tubes rather than fill to a line.
