ることができない。 For example, to test for drugs contained in racehorse urine, the urine is placed in an organic solvent such as chloroform, stirred, the drug is dissolved in the chloroform, the urine and chloroform are separated, and then the drug is tested. The drug is extracted by drying (concentrating) the chloroform containing the drug, and the drug is analyzed by chromatography or the like. Here, a dryer is used to dry the chloroform in which the drug is dissolved, and this dryer includes a vacuum dryer that evacuates the inside of the sample tube containing the solution, and a dryer that evacuates the inside of the sample tube containing the solution. Thermal evaporation dryers that heat the sample tubes, flash dryers that blow airflow into the inside of sample tubes, etc. have been put into practical use. In a vacuum dryer or a flash dryer that blows an air stream perpendicular to the liquid surface, the solution bumps or scatters, and the solution adheres to the lid of the sample tube, resulting in loss of extract. Solution attached to the lid may cause cross-contamination if the sample tube is replaced. Furthermore, in a heated evaporative dryer, if the temperature is raised to speed up drying, drugs with low boiling points will evaporate, making efficient drying impossible.

チユーブ１４，１５に接続されている。 In FIG. 1, 1 is a sample tube containing a test solution 2 in which a drug is dissolved, and the sample tube is a heating tank to which a fluid heated to 50°C to 100°C is supplied. It is located within 3. A lid 5 is attached to the upper part of the sample tube 1 via an O-ring seal 4.
is attached, and an exhaust hole 6 and air flow supply holes 7 and 8 are bored inside the lid body 5. The exhaust hole 6 is connected via a tube 9 to an exhaust means 10 such as a rotary pump. Note that 11 is a cooling trap for trapping the evaporated solution. The air flow supply holes 7 and 8 are connected to tubes 14 and 15, one end of which is open to the atmosphere, via air filters 12 and 13, respectively.

冷却されて元の液体に戻される。 In the above-described configuration, a solution such as chloroform in which a drug is dissolved is placed inside the sample tube 1, and then a lid 5 is placed on the top of the sample tube 1.
is attached via an O-ring seal. In this state, when the inside of the sample tube 1 is evacuated by the exhaust means 10, the air is blown out into the sample tube from the air flow supply holes 7 and 8 due to the pressure difference between the inside of the sample tube and the atmosphere. . Note that the air supplied into the sample tube 1 from the air flow supply hole is filtered through air filters 12 and 13.
Dust etc. have been removed in advance by here,
The airflow blown out from both airflow supply holes flows into the sample tube 1.
The air flow supply holes 7, 8 are arranged so that they do not collide perpendicularly with the inner wall of the sample tube in either the longitudinal or lateral directions, but obliquely collide with the inner wall of the sample tube, as shown by the dotted line F in FIG. is bored in the lid body 5. Figure 2 shows
It is a view of the sample tube 1 viewed from above, and shows the relationship between the supply ports 7a and 8a of both airflow supply holes 7 and 8 and the flow F of the airflow. By colliding such an air flow with the inner wall of the sample tube 1, the solution inside the sample tube starts to rotate without scattering, and as the speed of rotation increases, centrifugal force causes the solution inside the sample tube to rotate along the inner wall. It rotates. This rotation stirs the solution, widens the vaporization surface, and actively evaporates the solvent. This evaporation of the solvent is further accelerated because the inside of the sample tube is evacuated to vacuum, and furthermore, the sample tube 1 is placed in the heating tank 3 and the solution is heated. Then the sample solution is dried. The evaporated solvent passes through the exhaust hole 6 and is supplied to the cooling fin 11 via the tube 9, and the evaporated solvent in the cooling trap 11 is cooled and returned to its original liquid state.

め、大気が汚染されるのを防止できる。 As detailed above, in the present invention, since the sample solution is blown with air so as to rotate inside the sample tube, the vaporization area of the sample solution can be widened, the solution can be constantly stirred, and the solvent can be efficiently evaporated and the sample solution can be dried (concentrated) quickly. Furthermore, since the atmospheric air is supplied to the sample tube based on the pressure difference with the outside generated by exhausting the inside of the sample tube, a high-pressure air supply means such as a compressor is not required, and
The exhaust means can be used to discharge the solvent vapor, thereby reducing the size and cost of the apparatus and improving the drying efficiency of the solution. Furthermore, since the sample solution rotates without scattering,
There is no risk of sample solution adhering to the lid, cross contamination, and sample solution being wasted. Furthermore, since the solvent vapor exhausted by the exhaust means is adsorbed in the trap, it is possible to prevent the atmosphere from being polluted.
更に、又、本考案の実施例においては、試料溶

For example, heating within the sample tube is not necessarily required. Furthermore, if the air blown into the sample tube is heated and dried in advance, the drying speed can be further increased.
