在制剂中药液的过濾是个很重要的操作过程,它对制剂的質量有着直接关系。我們过去由于过濾不得法,所以在过滤的質量上和速度上都存在着問题,經过多次研究和試驗,利用垂熔玻璃漏斗安裝成簡易的自然減压过濾裝置。因此在过濾的質量和速度都显著的提高,現簡單的介紹如下: 一、裝置 1.垂熔玻璃漏斗:我們採用的是波蘭“jena”厂出品3号的,濾板直徑19cm(採用上海玻璃厂出品的4号或5号,“Pyrex”厂出品的M号,“jena”厂出品的3号或4号均可)。 2.橡皮塞:大小适宜,此漏斗管要粗些,中穿一孔恰能插入漏斗管,在旁側中部再穿一小孔使之成三通管,如圖1a。 3.細玻璃管:直徑2mm,長适宜,以安裝后紧接着滤板下面为度。兩端弯成直角,其一端由橡皮塞的大孔內向旁側小孔插出,如圖1 b。
In the preparation of liquid filtration is a very important process, which has a direct relationship between the quality of the preparation. In the past, due to the unfavorable filtration, we had problems with the quality and speed of the filtration. After many studies and experiments, we installed the simple natural decompression filter device with the frit glass funnel. Therefore, the quality and speed of filtration are significantly improved, is now briefly introduced as follows: First, the installation 1. Vertical melting glass funnel: We use the Polish “jena ” plant produced No. 3, filter plate diameter 19cm (using Shanghai Glass Factory produced 4 or 5, “Pyrex ” factory produced M, “jena ” factory produced 3 or 4 can be). 2. rubber plug: the size is appropriate, the funnel to be thicker, in a hole just inserted into the funnel, in the side of the middle and then wear a small hole so that the tee, as shown in Figure 1a. 3. Thin glass tube: Diameter 2mm, long suitable to install immediately after the filter plate for the degree below. Bent at both ends at right angles, one end of the large hole from the rubber plug to the side of the hole inserted, as shown in Figure 1 b.
