Further, reinforcing prop is additionally provided with, described reinforcing prop extends upwardly to from hole position bottom through support piece center
Support bottom.
Further, the height on described support side be support bottom to hole position upper limb height 1 to four/3rd/
Three.
In above-mentioned technical proposal, the notch depth of described card interface is 0.5 ~ 1.5cm.
As a kind of effective embodiment, the hole position installation test tube capacity of described rack for test tube is 30-50mL.
Further, there is the cue mark of test tube capacity on the non-interface of described rack for test tube.
As another effective embodiment party's mode, the hole position number of described rack for test tube is 8-15.
The utility model at least has following usefulness：
1. by the rack for test tube group of the rack for test tube of a variety of different sizes, in combination formation relative securement, suitable pair
Various ingredients Standard Stock solutions collect；, can be by the rack for test tube of different size for the Standard Stock solutions group of different capabilities
Hole position lay regular, and it is convenient that liquid level flushes sampling operation；It is sampled, during mark-on, test tube open height is consistent, nothing
It need to be had enough to meet the need between multiple rack for test tubes, operation is more convenient, reduces error；
2. another rack for test tube card interface is inserted into by clamping block by the clamping block of any rack for test tube and makes clamping build
Mounting means of the end in hole position, the cambered surface of clamping block header can be bonded quantitative test tube, avoid quantitative test tube displacement, work as setting
When cambered surface radius is slightly less than test tube radius, test tube top pressure cambered surface, while avoiding quantitative test tube from rocking, clamping block and card can be made
Interface engagement is more close.
3. by adjusting the height at support bottom and hole position bottom, the installation of the quantitative test tube of different size can be met, rationally
, the hole position installation test tube capacity of rack for test tube is 30-50mL, can meet the use of the most of experimental implementations in laboratory.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more easily understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining that this practicality is new
Type, it is not used to limit the utility model.
Embodiment
Such as Fig. 1, a kind of combined quantitative rack for test tube, it has 11 hole positions 1, and each test tube hole position 1 is in single-row arrangement, and
Four identical support pieces 4 are provided with each hole position 1, each support piece 4 is in cross from the bottom centre of hole position 1 to the inwall of hole position 1
Shape radiation is arranged and upwardly extended, and extremely engages to form support bottom 41 with the inwall of hole position 1, and is in lower recess, with examination in backing
The arcuation that bottom of the tube matches；Reinforcing prop 5 is additionally provided with, described reinforcing prop 5 is upward through the center of support piece 4 from the bottom of hole position 1
Extend at support bottom 41；Support bottom 41 continues up extension with the inwall joint of hole position 1 and forms sheet support side 42, support side
Breach, which is formed, between 42 and support bottom 41 accommodates area.
Such as Fig. 2-3, the area maximum two relative side of rack for test tube interface (2,2 ') parallel each other, two relative side
The card interface 31 and clamping block 32 of pairing are correspondingly arranged on, the described head end both sides of clamping block 32 are protruded to the left and right, and laterally
Face is in cambered surface 321；Described card interface 31 is formed down breach from the upper edge of hole position 1；The clamping block 32 of any rack for test tube passes through
Clamping block 32 is inserted into another rack for test tube card interface 31 and the head end of clamping block 32 is located in hole position 1.
As an improvement, the notch depth X of described card interface 31 is 0.5 ~ 1.5cm, in card interface 31 and the phase of clamping block 32
After mutual grafting, clamping block 32 can fully go deep into hole position 1, can reduce the slippage probability of card interface 31 and clamping block 32, when setting
The radius of cambered surface 321 for putting the head end lateral surface of clamping block 32 is slightly less than the corresponding radius for quantifying test tube, and with the examination of corresponding installation
