The special stain kits are not $1000.  Yes it takes approx. 1 hour or more
for the more complicated stains, and you can stain only 20 slides on each
module. But, you can stain a multiple staining procedures at the same time,
(GMS, Retic, PAS and many others).  Being a walk away system this allows you
to do other things while your slides are staining.  My technician love ours.
I did an extensive cost analysis before we bought the system and found that
it was less expensive when you consider hands on tech time.

There was a comment from last week that I just can't let go off. Robin F
told that a lab payed $1000 for a (one!) special stain kit from Ventana.
My, it sounds grotesque. That is around the amount I spend yearly on powder
and regents for special stains (well not totally, but close enough). Also, I
have heard that a run with 20 slides takes around one hour - in that time I
can stain 50-100 slides with various special stains. Doesn't sound optimal
to me.
Usually the dyes last for one week (with a daily top-up), and the powders
are almost of eternal life. So why accept these expensive kits with an
expiry less than 9 months?
Is it low volume labs that benefit from this kind of automation?
I welcome technical improvements and automation, but this, I do not know who
benefits besides from the vendor......?
Other opinions most welcome. Andrea.
