Vitawworth, a poultry expert at the University of Wisconsin, used the method of transplanting right ovary to make hens produce two eggs per day. After years of research, Vitavos found that although there are many follicles in the ovary of hens, only the follicles in the left ovary can develop into eggs one by one, but the right ovary is already degraded and it has not been able to develop follicles into eggs. . This is why the hen can only produce one egg at a time. He then performed surgery on the hen and transplanted him with a right ovary. In this way, the follicles can develop into eggs one by one in the transplanted right ovary. Since then, hens can produce two eggs a day. What's more interesting is that these eggs are sometimes produced once. After the hen has achieved two eggs per day by transplanting the right ovary, the egg production can be greatly increased. Erlenmeyer flasks are widely use in cell suspension culture, medium confifiguration, mixing and storage.It is suitable for culturing cell lines with high oxygen requirements. It can also be used to culture bacteria, fungi and animal and plant cells in suspension. Compared with culture flasks, dishes and spinner flasks, it requires less work and is an economical solution. Cell Culture tool ideal for media preparation, mixing and storage.Reduces the chance of experimental personnel being infected during bacterial culture work. erlenmeyer flask bulk,erlenmeyer flask for bacterial culture,flask erlenmeyer,Erlenmeyer Flask,cheap erlenmeyer flask Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yypcr.com
