Image showing experimental set up for the ‘hoovering’ of conidia from Aspergillus fumigatus crossing plates. Note particularly: (A) A 1000‐µl pipette tip, allowing precise targeting of conidia; (B) Conical flask containing 2% trigene disinfectant, killing conidia that have been hoovered; (C) Conical flask containing isopropanol, killing any remaining conidia from (B); (D) Final tube connected to a 10‐µm filter (not shown), in order to trap any leftover conidia, leading to the vacuum tap. The airflow is in the direction of A‐D in all circumstances.
