ようになつている。[Prior Art] Generally, in the case of a rotary evaporator, a sample container such as a flask attached to a mounting part of a rotary drive device is rotated in a heating device such as a water bath or an oil bath while heating the sample inside the sample container. Separation and collection is now possible using a collection flask.
試料の回収を図る回収フラスコは、接続管の取
付部に対して360度いずれの方向からでも脱着が
可能なボールジヨイントタイプと軸心方向にのみ
脱着が可能なコーンタイプとがある。 There are two types of collection flasks used to collect samples: ball joint types that can be attached and detached from any direction within a 360 degree angle to the connecting tube attachment point, and cone types that can be attached and detached only in the axial direction.
ボールジヨイントタイプ及びコーンタイプは、
回収フラスコの口元フランジ部と接続管の取付け
フランジとを接合させクランプによつて結合を図

ようになる。 In the rotary evaporator configured in this manner, the clamp 57 is removed to release the collection flask 51 after the work has been completed. In this case, since the collection flask 51 rests on the support portion 73, there is no need to support the collection flask 51, and it can be easily removed by one person. Next, the fixing bolt 63 is loosened to leave the arm base 61 in a free state, and the collection flask 51 is pushed down against the spring 67 so that the mounting flange 53 and the mouth flange 55 are vertically separated. Therefore, by lifting the recovery flask 51 in this state, the flask 51 can be removed by one person.
The mounting flange 53 and mouth flange portion 55 in the uncoupled state with the clamp 57 removed are connected to the spring 67.
Since it is a cone type, it can be removed without any trouble because it can be separated vertically by the action of .

なる。 Next, when installing, after placing the bottom of the collection flask 51 on the support part 73, press the flask 51 downward against the spring 67, align it with the mouth flange part 55 and the mounting flange 53, and then manually Let go. At this time, the opening flange portion 55 and the mounting flange 53 are brought into a bonded state in which they are in strong contact with each other due to the action of the spring 67, so after the clamp 57 is mounted in this bonded state, the fixing bolt 63 is tightened. As a result, the mouth flange portion 55 and the attachment flask 53 are supported in a securely connected state.
