You mean like the kind you glue acrylic with? What do you consider good results? What is the plastic glue bottle made of? What does the surface of the mercury look like inside that plastic glue bottle? Is there just a little bit of gray film on top?

Mercury will combine with anything that is even remotely chemically reactive with it and contaminate the mercury. There are very few plastics that are not. Even the plastic bottles that dentists used to get "triple distiller mercury" in for tooth fillings was reactive with mercury. That may be fine for an amalgam, but not for mercury that has to remain the highest purity possible.

If I am remembering correctly high purity polyethylene is one of the few that are not. I would find it hard to believe that a disposable glue bottle would be made of that. And that does not even start to consider the metal needle that is supplied with a disposable bottle.

All the materials a mercury dispenser is made of... the ones that come in contact with the mercury... must be completely un-reactive with the mercury over long periods of time.
