Liquids can be sucked into a collection bottle by using a vacuum pump to create low pressure in the bottle. Sufficient vacuum in the collection bottle is essential to support aspiration, but should not be so deep to risk evaporation of solvents. Adjustable suction power (and hence vacuum level) enables sensitive or powerful aspiration as needed. For optimum operational safety and convenience, self-closing quick couplings and a liquid level detector at the bottle are helpful. All components in contact with aspirated media should have high chemical resistance and be autoclavable. Depending on aspiration safety protocols, a collection flask made either of polypropylene or glass may be preferred.
