目前国内高等师范和理工科院校在有机合成实验中普遍采用标准磨口中（常）量有机合成制备仪。它体积大，耗用试剂较多，实验时间长，而且与当前的教学及教材不相适应。个别院校采用微量制备仪，虽可克服常量存在的缺点，但产量又太少，附属设备须全部更换，另外需购买大型检测设备；我们有鉴及此，设计了一整套少量化制备仪，从根本上解决了大和小的问题，又较适应教材，而又优于教材，节约了实验费用，缩短了实验时间，达到了教学目的
At present, domestic normal colleges and universities of science and engineering in the organic synthesis experiments commonly used standard grinding mouth (normal) amount of organic synthesis preparation instrument. It is bulky, consume more reagents, long experimental time, and with the current teaching and teaching materials do not meet. The use of micro-preparation apparatus in individual institutions can overcome the shortcomings of the constant, but the output is too little. All the auxiliary equipment must be replaced. In addition, large-scale testing equipment should be purchased. In light of this, we have designed a set of small- From the fundamental solution to the problem of large and small, but also more suitable materials, but better than teaching materials, saving experimental costs, shorten the experimental time, to achieve the purpose of teaching
