Dear Anita,

I addressed this point to Beth & HistoNet on the 18 August, we have been
fitting these controls to cryostats for over 20 years, they are fitted to
our clinical & research cryostats and they do not suffer from temperature
loss on the anti-roll plate, which would defeat the benefit of these
controls.

Best Regards
