The ZK-8 Liquid Suction Vacuum Pump is a compact and efficient aspiration system designed for precise and safe removal of liquids in laboratory environments. Ideal for routine lab work, the ZK-8 provides quiet operation, adjustable vacuum control, and a built-in collection system — making it perfect for cell culture, microbiology, and filtration applications. Equipped with an oil-free diaphragm pump, the ZK-8 ensures maintenance-free performance, while the chemical-resistant components make it suitable for handling corrosive fluids and biological waste. The integrated 1L or 2L autoclavable collection bottle includes an overflow protection system, helping to prevent contamination or equipment damage. Its lightweight, benchtop design is ideal for any lab needing clean, efficient, and reliable liquid suction without the use of external vacuum lines.
