This item is next up on the list of @Beakers labware to be auctioned (proceeds to family).
It’s in Bend & Heavy!!
Can’t find exact specs on it.
My new cryogenic immersion chiller used from ebay just got here today. My poly foam bath pan meant for cryo apps using alcohol got here too but my methanol is a few days out. So I dumped what rubbing alcohol there was into the pan and fired it up. As soon as the rubbing alcohol froze onto the finger the temp reading on the chiller went to -76C or so. The unit has a setpoint but it measures the coolant. Apparently when the ice forms around the cold finger it causes the coolant to get real cold.
Methanol should be in soon. This bath froze on the finger at around -30C owing to the 70/30 iso to water mix. Check out frozen rubbing alcohol! The frozen vapor was gently lifting off the surface of the liquid where water in the air cooled and condensed.
Is this cool or what?
