What do I use for culture vessels instead of test tubes and flasks?
Baby food jars make great culture vessels. They can be sterilized in a pressure cooker with the original metal caps or in a microwave with polypropylene caps. Various food containers, such as Gladware, can also be used as culture vessels and processed in the microwave. If you are not sure how a particular plastic will hold up in the microwave, be sure to do a test run and have a paper plate under the item.
