I have a used VWR Mini Vortexer.
$80.00 Free shipping (original $375)
This is NOT a stir plate it is a vortexer. It has the flat plate adapter for smaller flasks beakers.
I used it to stir white labs yeast tubes. Was going to keep to make a yeast library in test tubes then use it to resuspend the yeast before I pitched. Anyways, first PM, its yours.
Thanks for your interest, I get a lot of used lab equipment and new glass ware Ill post more up when I clean my garage out..
