精子密度仪

How to use the Colormeter

如何使用密度仪

1. We are going to proceed to the counting of the doses with the colorimeter. For

that ,we willplace 10ml of the extendersolution in each bottle.

我们将用精子密度仪进行精液头份测算，

首先我们往每个比色皿里倒入10ml 的对比液（蒸馏水即可)

2. …and in one of them we will add plus 0.4ml of pure semen witha Micropipette

接着，往其中一个比色皿里，使用移液器加入0.4 毫升的纯精液。

3. We turn on the colorimeter (ON/OFF),place the bottle standard (the one thatonly has extender solution) …

按开关键（ON/OFF)，打开密度仪,然后放入比色皿（那个只添加了对比液的比色皿）确定黑色盖子已经盖好，三角箭头互相对齐

4.…and detrmine the value of reference (which will be 0,0) perssing the key board(ZERO)

紧接着按归零键（ZERO）归零确定参考值…几秒钟后会显示0.0

5. Next,we take off the bottle standard and replace it for the other one (the one that

has extender solution + semen ), previously well mixed, and press the keyboard(READ /DIRECT )obtaining a value .

接下来，取下标准比色皿，换上另一个（那个装有对比液和纯精液的）比色皿。然后按下（READ/DIRECT )键。

6.…after a few second appear one value (in the photo case )，Try to find theaprox .value obtained on the table.

然后一个数值就会出现在密度仪的窗口中,根据读取的数值，对照表格找出相近的数值。

一份合格的精液中应含有30 亿有效精子，精子活力在70%以上，每份稀释后总剂量在80ml 以上。由此我们可搭配出最合理的稀释倍数。
