Draw back plate moves, so that spill elastic sponge clamps volumetric flask, can effectively prevent from into volumetric flask toppling in beaker
During liquid, somewhat volumetric flask will be done fall by imprudence, makes the failure of an experiment, as preferable, can replace slack adjuster
The baffle plate of base side, by the regulation of two slack adjusters, spill elastic sponge can be more efficiently adjusted, and then press from both sides
Tight volumetric flask, simultaneously for glass containers such as the single port bottle for holding liquid, there-necked flasks because bottom is spherical, therefore it can also be placed on
It is clamped on base.
General principle of the present utility model, principal character and advantage has been shown and described above, it is new not departing from this practicality
On the premise of type spirit and scope, the utility model also has various changes and modifications, and these changes and improvements both fall within requirement and protected
The scope of the utility model of shield.
