[Histonet] freezing in isopentane

[Steven Slap]

Hi HistoNetters

At risk of someone writing "nice ad" again, there is an instrument, the
"Clini-RF", from Bright Instruments, that would be very useful in resolving
some of these issues.  Instead of using liquid nitrogen to cool the
isopentane, the Clini-RF is a stand-alone freezer with a -80 degree tank
which can be used for direct immersion in isopentane.

Although this instrument is available from Hacker Instruments in the United
States, I get nothing except satisfaction from seeing it sold.

best regards,
