Hi,
I found these little circle caps/membranes(?) in my lab, they are stored in an odourless liquid that is not water (I tried mixing some in and could see the fluids mixing). I work in a biochemistry lab that primarily does protein expression in bacteria and yeast, purification, and UV-Vis spectroscopy. Does anyone know what these are?
Possibly a microdialysis cassette, although I have not seen one like this before. Is there a membrane on each side of the hole?

The white one looks like magnetic beads used in mixing on magnetic stirrer.
Look like end seals with opening (fits around a pipet) for dialysis tubing.
This could be two micro-dialysis chambers swimming in a beaker with fluid. The fluid is stirred with a magnetic flea to accelerate the dialysis process.
Adam B Shapiro Engelbert Buxbaum Randolph B Caldwell I think you are all correct, they‘re probably microdialysis cassettes. I can’t find their exact make online, but at least this places them! Thank you for your answers!!
You can make such cells easily from an Eppendorf vial and a piece of membrane (doi:10.1016/S0003-2697(02)00639-5)
