Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but this should not be interpreted as of the present utility model
The scope of above-mentioned theme is only limitted to above-described embodiment.
As Figure 1-3, a kind of chemical experiment reagent rack, including support 1, LED light 2 and indicating member 4, support
1 is provided with the positioning hole for holding test tubes 3, and LED light 2 is located at the side of support 1, positioning hole correspondence position；Indicating member 4
Positioned at the bottom of support 1, the bottom correspondence position of test tube 3；Indicating member 4, including supporting plate 41, spring 43 are sequentially provided with from top to bottom
With bottom plate 42, the top of spring 43 is connected with supporting plate 41, bottom is connected with bottom plate 42；The side of supporting plate 41 is provided with guide rod 44, leads
On bar 44 sliding block 45 is slidably provided with the correspondence position of supporting plate 41；Sliding block 45 accesses LED light loop with supporting plate 41,
When sliding block 45 contacts with supporting plate 41, LED light is in the conduction state.The position of sliding block 45 is set according to warning value in advance,
When amount of reagent is less than setting value in test tube 3, spring 43 moves upwards, and supporting plate 41 contacts with sliding block 45, LED light loop
It is in the conduction state, remind operating personnel to pay attention to underdosage, avoid influenceing to test.
