Is this septum suitable for injection? Can I use this flask for microbial culturing to prevent gas exchange.
1 answer-
The septum used with this product is sold under Catalog No. 27177. This type of septum is suitable for sampling with a needle, but septa typically are replaced after puncturing in highly sensitive analytical applications to ensure reproducibility.
The cap and septum in this product form a gas-tight seal, making it suitable for preventing environmental gas exchange in microbial culture experiments.Helpful?
