Abstract
Provided is a watch glass. A round hole with the diameter as 1cm is arranged at the bottom of a recessed portion of the watch glass, and a glass nozzle is arranged at the lower end of the round hole. The length of the glass nozzle is 1cm. The watch glass is simple in structure and practical in function. In the process for heating and dissolving a sample, liquid reagent can be added directly without opening the watch glass when the reagent is required to be added, so that the watch glass is convenient, saves time and facilitates operation.
Description
Technical field
The utility model relates to a kind of surface plate.
Background technology
At present, surface plate is as requisite glass wares in the assay process, and it mainly is to cover at beaker to prevent that solution from splashing when the heating for dissolving sample, plays the effect of lid.The original surface ware is glassware, toroidal, the centre is slightly recessed, in heating for dissolving sample process, cover surface plate after, if when adding liquid reagent, the surface plate of must moving away one by one, loaded down with trivial details, time-consuming.
