Is closed with a lid 11, and an exhaust hole 1 is formed in a side wall of the apparatus 1.
3, and an exhaust pipe 14 is connected thereto to discharge the solvent vapor to the outside. Therefore, since there is no need to plug and exhaust pipes for each test tube as in the past, there is no need for caps and exhaust pipes for plugging, which reduces the number of parts and makes the piping structure simpler. Is easier,
This can be manufactured at low cost. In addition, with the above-described configuration, a complicated cap attaching / detaching operation for each test tube is not required, so that the operation can be performed easily and quickly, and the solvent vapor can be discharged to the outside with a simple configuration.

The block 2 is heated, the block 2 is heated, the nozzle 6 is positioned above each test tube 4, the lid 11 is closed, and the evaporator 1 is sealed. In this case, since the upper part of the test tube 4 is open, the flexibility of the position of the nozzle 6 can be obtained.

And the effect of the liquid level drop is compensated for, so that the evaporation rate of the solvent 5 does not decrease, a substantially uniform evaporation rate can be obtained, and the solvent 5 can be evaporated to dryness quickly.

The solvent 5 can be reasonably and quickly evaporated to dryness. Therefore, if the maximum blowing gas flow rate at which the solvent 5 is not scattered to the outside is input by a program according to, for example, the liquid level drop of the solvent 5, the blowing gas having a flow rate corresponding to this is obtained, and the ideal solvent is dried to dryness.
