A sampling pump that can dissolve solids into a liquid is needed
Thread Content
The experiment requires heating a solid reactant with a boiling point of 180 degrees Celsius to a liquid state, and then adding this liquid in a measured amount to the reaction. It is usually plunger pumps and cross-flow pumps that operate in a liquid state; solid thermal melting is rare. I would appreciate it if those who know could tell me which brands are available
I didn’t understand; please explain it more clearly.
It is capable of pumping in samples with a melting point of 60–70 degrees Celsius, and the pump needs to be able to maintain heat.
