Through letting in cold and hot source (cold water, hot water or hot oil etc.) circulation heating or cooling reaction in the cavity to pressing from both sides cover and lower half bottle, the constancy of system temperature makes the reaction accurate, and easily control makes experiment reaction convenient operation, and is safer simultaneously, practical, also can carry out the series heating to the flask that the several needs the heating even, also can reduce the cost of heating like this.

In the flask, the distance between the jacket and the outer side wall of the lower bottle body is equal.

In the flask, an elastic sealing element is arranged between the first flanging and the second flanging.

After the upper bottle body and the lower bottle body are fixed, the elastic sealing element can increase the air tightness of the joint of the upper bottle body and the lower bottle body.

In the flask, the adjusting bolt is made of a plastic material.

The adjusting bolt is made of a plastic material, and cannot damage the flask made of a glass material.

In the flask, the upper half bottle body and the lower half bottle body are both in a semi-spherical shape.

Because the stress distribution of the spherical reaction cavity in the space of 360 degrees is the best and the most uniform, the internal pressure which can be accepted by the main body can be maximized, and the bearing pressure of the glass reactor is improved.

In the flask, the surfaces of the first flanging and the second flanging are frosted surfaces.

The surfaces of the first flanging and the second flanging are frosted surfaces, so that the first flanging and the second flanging can be attached more tightly.

Compared with the prior art, the flask has the advantages that: the first flanging of the first bottle body and the second flanging of the second bottle body are firstly attached to each other, the contact area of the fixed positions of the first bottle body and the second bottle body can be greatly increased, then the first flanging and the second flanging are fixedly connected through the plurality of fastening devices, the fastening devices are convenient to disassemble and assemble, only the adjusting bolts need to be rotated, therefore, the stability of connection of the first bottle body and the second bottle body can be improved, the air tightness is guaranteed, and the first bottle body and the second bottle body are convenient to disassemble and assemble.
