摘要
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。
The normal-quantity production sets used in organic chemosybnthesis experiment in most teacherscolleges and universities consume quite a lot of reagents and take long operatiog hours. Some colleges use micro-quantity sets, but the products are of so small amount that they have to be examined with auto analyzers, which means that all the already existing auxilaiaies have to be changed. To solve this problem, the authors have designed a series of small-quantity production sets, whcih can save experimental expenses and operatiog hours.
