I bought these with the intentions of using them for dosing Trace elements that need to be shaken before dosed, but now that I'm breaking down my frag system, I no longer need these. They are both brand new, and have not been used for more than turning them on to test them. I also have two brand new 500ml beakers. One was used with rodi to test the stirrers when I first bought them.
$125 for all.
