Abstract

本发明公开了一种采样皿，包括皿盖和皿体，所述皿体包括内侧壁，外侧壁，上皿底，下皿底和位于内侧壁和外侧壁之间的环形积水槽，所述积水槽底部设有微孔，所述微孔均为盲孔且环状分布在积水槽底部，所述积水槽中间同心设有两圆形隔条。该采样皿通过虹吸效应，来吸附固定收集产生的积水，从而避免了在使用过程中产生积水外流污染工作环境。

Description

一种采样皿
技术领域
本发明涉及培养用具技术领域，尤其是一种采样皿。
背景技术
采样皿是进行细菌或细胞培养使用最多的一种培养工具，传统的采样皿是由圆形的皿盖和皿体组成，在琼脂热浇铸成品后到使用采样皿期间，会存在以下问题：因为制作、存放、使用过程中的环境温度差异与水汽的挥发作用，可能会在采样皿内表面产生水汽或积露，对培养物的生长和培养物的观察均会造成不利影响；此外在使用过程中采样皿倒置时培养基会掉下来而且积露外流会对使用环境造成污染。
发明内容
为解决上述技术问题，本发明提供一种采样皿，避免使用过程中产生积水外流污染工作环境。
本发明采用的技术方案是：一种采样皿，包括皿盖和皿体，其特征在于，所述皿体包括内侧壁，外侧壁，皿底和位于内侧壁和外侧壁之间的环形积水槽，所述积水槽底部设有微孔，所述微孔均为盲孔且环状分布在积水槽底部。
优选的，所述微孔的直径不大于0.8mm。
所述积水槽中间同心设有两圆形隔条。
所述皿盖由盖顶和盖壁组成，所述盖顶与盖壁之间以圆角过渡连接。
所述皿盖内表面涂覆有疏水材料。
所述皿体的内侧壁向内倾斜。
优选的，所述内侧壁的倾斜夹角a范围为70°-85°。
所述皿底向上球面凸起。
所述内侧壁、皿底和积水槽内均涂覆有亲水材料。
本发明的优点如下：在积水槽内设置隔条和微孔，通过这种结构的虹吸效应，来吸附固定产生的积水；积水槽内涂覆有亲水材料，可加强对积水的吸附作用，避免了在使用过程中尤其在采样皿倒置时产生积水外流污染工作环境；皿盖内表面涂覆有疏水材料，可防止产生的水汽聚积在皿盖；盖顶与盖壁之间以圆角过渡连接，可以使产生的水汽更快地流向积水槽；皿体的内侧壁和皿底涂覆有亲水材料，可以吸附固定培养基，皿体的内侧壁向内倾斜一定角度可以防止在采样皿倒置时培养基掉落，皿底向上球面凸起的结构设计，可减小内侧壁和皿底的夹角，进一步防止培养基掉落。

具体实施方式
下面结合附图和具体实施例对本发明的技术方案作进一步的说明，但本发明的保护范围不限于此。
如图1，图2和图3所示，一种采样皿，包括皿盖和皿体，所述皿体包括内侧壁3，外侧壁4，皿底5和位于内侧壁3和外侧壁4之间的环形积水槽6，所述积水槽6底部设有微孔8，所述微孔8均为盲孔且环状分布在积水槽6底部，微孔8的直径不大于0.8mm，为了进一步加强对积水的吸附作用，积水槽6均涂覆有亲水材料，且在积水槽6中间同心设有两圆形隔条7，本实施例中微孔8均匀分布为内、中、外三环；两隔条7分别位于内环与中环、中环与外环之间且两隔条7之间的区域宽度小于其他两区域的宽度构成类似微槽的结构产生虹吸效应。
为了防止产生的水汽聚积在皿盖，本发明在皿盖内表面涂覆有疏水材料。
为了使产生的水汽更快地流向积水槽6，本发明皿盖的盖顶1与盖壁2之间以圆角过渡连接。
为了防止在采样皿倒置时培养基掉落，本发明中皿体的内侧壁3向内倾斜，皿底5向上球面凸起减小内侧壁3和皿底5的夹角，在内侧壁3和皿底5均涂覆有亲水材料，本实施例中内侧壁3的倾斜夹角a范围为70°-85°。
最后应当说明的是：以上实施例仅用以说明本发明的技术方案而非对其限制，对未脱离本发明精神和范围的任何修改或者等同替换，其均应涵盖在本发明的权利要求范围当中。
