Just make sure that all of your test cylinders are of one design or the other.
Mixing them will add variability to an already highly variable assay.

  I believe (at least in the past) I purchased cylinders from VWR with the
beveled edges.  I have found that the cylinders from A. Farmer were of higher
quality (dimensions, finish, etc.).

For those of you doing cylinder-plate assays,

Is there a difference between using stainless steel (SS), beveled-edge
cylinders versus SS flat bottom cylinders?

We can get flat bottom SS cylinders from Arthur Farmer.  Does anyone know of
any sources of the SS beveled-edge or flat-bottom cylinders?

Thank you,
