We are planning to purchase a new micro-balance for weighing of EA-IRMS
samples and other purposes. We will require readability of about 1-2 ug
(+/-2-4 ug). As these are quite costly (e.g. Mettler AX Series - >$14k
USD), and sometimes tricky instruments to maintain, I am wondering if any
Listmembers have recently researched new micro-balances and then made a
purchase decision. And if so, were you pleased with the performance,
stability, and reliability of the micro-balance you purchased? Was it
robust enough for a multi-user environment? Was the price negotiable from
the list price? Any models to avoid?
Any suggestions and advice are greatly appreciated.
