Magnetic susceptibility balance

Submitted by Dave Finster / Wittenberg University on Mon, 03/29/2010 - 13:38

I am writing up a "wish list" for my inorganic chemistry lab.  I seek advice.  Johnson-Matthey has the magnetic susceptibility balance (MSB) that seems like "the standard" for educational lab.  Can anyone advise on getting the "Mark I" vs. the "Auto MSB?"  Also, do you know the approximate prices for each of these two instruments?
