在野战条件下,将按规定制备的注射液装入容量为20升的大玻璃瓶中。为了用野战药房过滤器进行过滤,把原液从大玻璃瓶中分装在5升的小玻璃瓶里,大玻璃瓶的底部安有导管。但这种装置存在着严重的缺点:大玻璃瓶没有刻度,并由于弯月面过宽,要想标示大玻璃瓶里所制备的液体是否达到所要求的容量是很困难的。 In field conditions, the injection prepared according to regulations into large capacity glass bottles of 20 liters. In order to filter with a field pharmacy filter, the stock solution was dispensed from a large glass bottle into a 5-liter glass vial with a catheter at the bottom. However, this device has the serious disadvantage that large glass bottles are not graduated and because the meniscus is too wide, it is difficult to indicate whether the liquid prepared in large glass bottles has reached the required capacity.
