Pipetting is not practical or convenient for aseptically filling or emptying large culture vessels.

As a result, pouring is often used but this increases the risk of contamination. To solve this problem Corning has developed Aseptic Transfer Caps for filling disposable 1L, 2L and 3L Erlenmeyer and 500mL and1L Spinner Flasks. These new transfer caps will both reduce contamination and enhance the productivity of your cell culture operations.
