Thermocyclers, Ericomp

You can get a demo machine for a few days. Before settling on an
Ericomp SingleBlock (the 96 well/microplate model), I spent a week
using a demo Ericomp TwinBlock and an MJ Research PTC100-96V. I
liked both machines; what convinced me to go with Ericomp was the
included in-sample temperature probe and the 3-year warranty. Plus
their pricing is pretty aggressive. Also, I needed a machine in a
big hurry, and the West Coast rep (Chris Alvis) did me the huge
favor of getting me my cycler in record time (this reminds me that I
still owe him a thank you for letting me make some important

More to your point: What I liked about the TwinBlock I demo'd were:
(1) the in-sample temperature probe seemed to increase the
consistency of my reactions slightly (maybe this was wishful
thinking?); (2) having two separate blocks holding two different
tube sizes turned out to be more useful than I would've initially
imagined -- if I had had the money, I would've strongly considered a
two-block system. (3) programming was reasonably easy (still not
great, but a big step ahead of my old Coy). What I didn't like so
much was the noise level (the fans in the Twin are something else);
some minor quibbles with the fit and finish of things (there is a
screw in front of the block that pushes up the gasket and prevents
easy seating of a microplate without a bit of crimping.
Nevertheless, the machine did well enough, and I bought its little
brother and 4 months later am still pretty happy with it (by the
way, we're talking about the thermoelectric models here). 

No connection with Ericomp and views are mine, not UCLA's, etc.,
