Optimal thermocouple placement – Get perfect thermocouple placement every time, by using our distillation heads together with these thermowell adapters.
#4 Chem-Thread – For quick and easy insertion/removal of your thermocouple probe into the well.
Viton O-ring – Keeps the cap and seal of your thermocouples air-tight.
Increased surface area – The addition of the thermowell to the thermocouple will create more surface area for expanding vapors to cool and condense on.
American-made borosilicate glass – This glass can be subjected to repeated thermal stress with a greatly reduced chance of breakage.
Comes in two sizes – We carry both a 24/40 jointed thermowell and a 34/45 jointed thermowell.
