Cleaning, maintenance and replacing, improve the flexibility of support frame.
Preferably, the bookcase body sliding is connected with the show window for opening and closing cupboard chamber, and the show window includes vertical direction
Upper sliding is connected to the cupboard frame of bookcase body and horizontal direction sliding is connected at least two blocks glass of cupboard frame.
By using above-mentioned technical proposal, in experimentation, a small amount of gas can flow from the condenser pipe mouth of pipe in condenser pipe
Go out to enter cupboard intracavitary, set show window gas can be prevented to be flowed into laboratory, it is to avoid harm staff is physically and mentally healthy, and
And need need to only to open corresponding glass when observing the condenser pipe of some position, without opening whole show window, it is to avoid cupboard
The gas of intracavitary is flowed into laboratory.
Preferably, the glass outer side is fixedly connected with handle.
By using above-mentioned technical proposal, it is easy to pull glass, reaches the purpose for being easy to observation.
Preferably, the bookcase body is provided with two support frames, two water supply installations, two dresses that supply water positioned at cupboard intracavitary
Setting in the both sides of two support frames.
By using above-mentioned technical proposal, the condenser pipe on two support frames can be connected respectively a water supply installation
（It is i.e. in parallel）, all condenser pipes use same water supply installation on relative to two support frames（Connect）, using two water supply
Condenser pipe work during device on two support frames and suspend without interference with having the advantages that to be easy to control.
In summary：The utility model has had the advantage that one is that instead of brandreth by support frame and clamp assemblies
Platform, is that bookcase body vacates big quantity space to place more condenser pipes and conical flask, reaches the purpose for improving conventional efficient；Its
Two is detect by two water supply installations of setting to sample in front two rows conical flask respectively, reach and are easy to control to carry out
The effect of experiment.
