I am trying to find a cheap Chinese manufacturer of sterile bioprocessing bags up to 1,000mL in volume. There are a number of these available from name brands such as Sartorius Flex-Boy and Labtainer but they are expensive at about $25 per bag. I am wondering if there is a manufacturer in China that can make a similar product but at much cheaper price. I have tried to look on Alibaba but can't seem to find any but that may be the search terms i am using though.
I just want a few contact details for manufacturers.
