Best answer
Correct choice is (a) Pasteur pipettes

The best explanation: The sterile filters in mini fermenters are made from cut down Pasteur pipettes which are attached by silicone tubing to needles. The tubes (inlet and outlet) in the mini fermenters are shaped with sterile filters which have hypodermic needles and the tip of needles pass through septa.
