Description

异形离心管
技术领域
本实用新型涉及一种异形离心管。
背景技术
离心管在医学、生物学、物理、化学等各领域，以及在众多产业中应用广泛。目前离心管的管体都是一旋转体，即各处的横截面为圆形，而且管体绝大部分为圆柱体。这种圆形横截面使得离心出来的物质分布仍较为分散，聚集度不高，不利于后续的收集。而且对于微量颗粒物质，圆形横截面的离心管不易确定其聚集的大致部位。
实用新型内容
本实用新型所要解决的技术问题在于：提供一种异形离心管，其结构简单，且能避免离心出来的物质分布较为分散，聚集度不高的问题。
为解决上述技术问题，本实用新型所采用的技术方案是：一种异形离心管，具有一管体，所述管体为具有非圆形的横截面的非旋转体，所述横截面靠一侧处具有一个狭窄的聚集区。
优选地，所述管体横截面为三角形，所述聚集区为三角形的任意一个顶角区域。
优选地，所述管体横截面为椭圆形，所述聚集区为椭圆形的长轴方向上任意一端的弧顶区域。
优选地，所述管体横截面为半椭圆形，所述聚集区为椭圆弧的弧顶区域。
本实用新型的有益效果是：本实用新型异形离心管的管体为非旋转体，其横截面不是圆形，而是各种异形的横截面，例如：椭圆形、半椭圆形或者三角形等，具有一个狭窄的聚集区，能够使离心后分离出来的物质更集中地聚集在离心管的聚集区部位，更便于收集，对于微量颗粒物质，用本产品离心后更易确定其大致部位，收集更方便。本实用新型异形离心管可广泛应用于生物学、医学、物理、化学等学科领域科学研究和各产业，只要是从溶液中通过离心的方法沉积某种颗粒物质，均可用到本实用新型异形离心管。
附图说明
图1为现有离心管的横截面示意图。
图2是本实用新型一种异形离心管的横截面示意图。
图3是本实用新型另一种异形离心管的横截面示意图。
图4是本实用新型又一种异形离心管的横截面示意图。
下面结合附图对本实用新型做进一步描述：
具体实施方式
如图2所示，本实用新型提供一种异形离心管，其包括一管体，所述管体为具有非圆形的横截面的非旋转体，其可以设计成各种异形的横截面，在横截面的靠一侧处设有狭窄的聚集区。
所述管体的横截面可以有多种变化，如图2所示，所述管体的横截面为三角形，所述聚集区为三角形的任意一个顶角区域。
如图3所示，所述管体的横截面为椭圆形，所述聚集区为椭圆形的长轴方向上任意一端的弧顶区域。
如图4所示，所述管体的横截面为半椭圆形，所述聚集区为椭圆弧的弧顶区域。
在实际制造时，根据市场需求，确定异形离心管的尺寸和所用材料(如金属，高分子材料等)，然后造模铸出即可。为提高异心离心管的安全性能，应通过实验确定每种产品的最大承受力和其它各种物理性能参数。
而在使用时，将本实用新型异形离心管放置在常规离心机转子的样品桶(圆桶形)，平衡，固定即可。或者放置在与异形离心管配套的样品桶。离心时，溶液中的颗粒物质在离心力的作用下，将集中于某一点，而椭圆形或者半椭圆形或者近椭圆形的弧顶区域或者三角形的顶角区域为颗粒物质在小范围内聚集提供了物理空间。假设离心机的转子中心位于图中所示离心管的左侧的某一点，则如图2至图4所示，离心后颗粒物质集中沉积于异形离心管的右边，图中以细点来表示离心后沉积的颗粒物质，与图1所示的现有圆形横截面的离心管相比，颗粒物质的沉积更为集中，便于后续的收集。
