超滤器是生化制药和研究生物大分子的常用设备。我们自行组装2.5L超滤器,经使用研制小牛胸腺肽,证明性能可靠,效果良好,设备易得,成本低。所用器材:ZY-2.5型正压过滤器(上海医药工业研究院实验药厂、宁波市姚江过滤器厂)、ZD-2型调速振荡器(江苏金坛环保仪器厂)、WM-4型无油气体压缩机(天津医疗器械二厂)各一台,压力表(5
Ultrafilters are common equipment for biopharmaceutical and research biological macromolecules. We assemble 2.5L ultrafilter by ourselves. After using calf thymus, we proved that the performance is reliable, the effect is good, the equipment is easy to obtain and the cost is low. Equipment used: ZY-2.5-type positive pressure filter (Experimental Institute of Shanghai Pharmaceutical Industry Research Institute, Ningbo City, Yaojiang filter plant), ZD-2 speed oscillator (Jiangsu Jintan environmental instrument factory), WM-4 Oil-free gas compressor (Tianjin Medical Devices Factory) each one, pressure gauge (5
